Mammals from Tamaulipas, Mexico
By
ROLLIN H. BAKER
Forming the northeastern border of Mexico, Tamaulipas extends
in an elongated, north-south direction from the Temperate into the
Torrid Zone and contains faunal elements from both the Nearctic
and Neotropical regions. The mammals are less known than those
from some of the bordering states; for the most part collecting has
been limited to a few localities, chiefly along the Pan-American
Highway. Accordingly, as a step towards a long-range study of
the mammals of Tamaulipas, the Museum of Natural History of the
University of Kansas acquired from William J. Schaldach, Jr., a
small, but significant, collection of mammals taken in the last
month of 1949 and the first four months of 1950.
Collections were made at several places in the vicinity of Ciudad
Victoria, including localities along the humid, eastern face of the
Sierra Madre Oriental. Many of these specimens were obtained
near camps made west of the village of El Carrizo. This small
community is on the Pan-American highway, 70 kilometers (by
highway) south of Ciudad Victoria. The resulting collections,
which are reported upon here, disclose that several tropical mammals
range farther northward than previously reported. Funds for
financing the field work were made available by a grant from the
Kansas University Endowment Association.
ACCOUNTS OF SPECIES
Didelphis mesamericana mesamericana Oken
Central American Opossum
Did[elphys] mes-americana Oken, Lehrbuch d. Naturgesch., pt. 3, vol. 2:1152,
1816. (Type from Northern Mexico.)
Didelphis mes-americana Allen, Bull. Amer. Mus. Nat. Hist., 16:256, August
18, 1902.
Specimens examined, 2 as follows: 36 km. N and 10 km. W Ciudad Victoria,
1 km. E El Barretal, on Río Purificacíon, 1; 12 km. N and 4 km. W
Ciudad Victoria, 1.
Philander opossum pallidus (Allen)
Four-eyed Opossum
Metachirus fuscogriseus pallidus Allen, Bull. Amer. Mus. Nat. Hist., 14:215,
July 3, 1901. (Type from Orizaba, Veracruz, Mexico.)
Philander opossum pallidus Dalquest, Occ. Papers Mus. Zool., Louisiana
State Univ., No. 23:2, July 10, 1950.
[Pg 210]
Specimens examined, 3 from 70 km. [by highway] S Ciudad Victoria and
2 km. W El Carrizo.
Remarks.—These three specimens have proportionately longer
tails than typical P. o. pallidus from central Veracruz; total length
and length of tail of two adult males are 575, 295, and 568, 290 respectively.
This marsupial has been previously unrecorded from Tamaulipas
or from so northward a locality. The four-eyed opossum evidently
ranges northward along the east face of the Sierra Madre Oriental
within the humid division of the Upper Tropical Life-zone. These
animals, all males, were taken in steel traps baited with the bodies
of skinned mice or birds. Sets were made along well-used trails
leading from a densely vegetated arroyo into a corn field through
openings in a fence of roughly piled logs. The elevation of this
locality is approximately 2500 feet.
Desmodus rotundus murinus Wagner/span
Vampire Bat
D[esmodus] murinus Wagner, Schreber's Säugthiere, Suppl., 1:377, 1840.
(Type from Mexico.)
Desmodus rotundus murinus Osgood, Field Mus. Nat. Hist., publ. 155, zool.
ser., 10:63, January 10, 1912.
Specimens examined, 9 as follows: 12 km. W and 8 km. N Ciudad Victoria,
2500 ft., 3; 70 km. [by highway] S Ciudad Victoria and 6 km. W of the
[Pan-American] highway [at El Carrizo], 6.
Remarks.—Vampire bats were taken at two caves. At the cave
called "Los Troncones", 12 kilometers west and 8 kilometers north
of Ciudad Victoria, seven bats were shot down; three were saved.
The second cave, south of Ciudad Victoria, was considerably
damper than the first. Vampires were found in a small side chamber;
nine bats were knocked down. No other kinds of bats were
present in either cave.
Sylvilagus floridanus connectens (Nelson)
Florida Cottontail
Lepus floridanus connectens Nelson, Proc. Biol. Soc. Washington, 17:105,
May 18, 1904. (Type from Chichicaxtle, Veracruz, Mexico.)
Sylvilagus floridanus connectens Lyon and Osgood, Catal. Type spec. Mamm.
U. S. Nat. Mus., Bull. 62:32, January 28, 1909.
Specimens examined, 2 from 70 km. [by highway] S. Ciudad Victoria and
2 km. W El Carrizo.
[Pg 211]
Sciurus aureogaster aureogaster F. Cuvier
Red-bellied Squirrel
[Sciurus, by implication] aureogaster F. Cuvier, Hist. nat. mammifères, vol.
6, livr. 59, pl. with text, September, 1829. Binomial published at end of work
only, vol. 7, tabl. generale et méthodique, p. 4, 1842. (Type from "California"
= eastern Mexico.)
Specimens examined, 13 as follows: 43 km. S Ciudad Victoria, 1; 70 km.
[by highway] S Ciudad Victoria, and 6 km. W of [Pan-American] highway [at
El Carrizo], 3; 70 km. [by hwy.] S Victoria and 2 km. W El Carrizo, 9.
Remarks.—These colorful squirrels were taken in thick timber
and brush, and locally are referred to as "ardilla pinta" or "ardilla
colorada." One female obtained on January 22 is black. Local
hunters state that these squirrels are most active early in the morning
and late in the afternoon. Two squirrels were seen in copulation
on January 19.
Sciurus negligens Nelson
Little Gray Squirrel
Sciurus negligens Nelson, Proc. Biol. Soc. Washington, 12:147, June 3, 1898.
(Type from Alta Mira, Tamaulipas, Mexico.)
Specimens examined, 17 as follows: 70 km. [by highway] S of Ciudad Victoria
and 6 km. W of the [Pan-American] highway [at El Carrizo], 5; 70 km.
[by highway] S Ciudad Victoria and 2 km. W El Carrizo, 12.
Remarks.—Referred to as "ardilla chica" locally, these squirrels
were most frequently seen in the dense forest of the lower, elevations.
Active both in trees and on the ground, these animals were
reported as being destructive to corn crops. Females taken in January
were lactating.
Heterogeomys hispidus concavus Nelson and Goldman
Hispid Pocket Gopher
Heterogeomys hispidus concavus Nelson and Goldman, Proc. Biol. Soc.
Washington, 42:148, March 30, 1929. (Type from Pinal de Amoles, Queretaro,
Mexico.)
Specimens examined, 5 as follows: 70 km. [by highway] S Ciudad Victoria
and 5 km. W El Carrizo, 4; 70 km. [by highway] S Ciudad Victoria and 2 km.
W El Carrizo, 1.
Remarks.—These gophers have been compared with specimens
of H. h. hispidus from Veracruz (5 km. N Jalapa and 4 km. WNW
Fortin) and with specimens of H. h. concavus from San Luis Potosí
(Xilitla and vicinity and 3 mi. NW Pujal); the latter were examined[Pg 212]
through the courtesy of Dr. George H. Lowery, Jr., of the
Museum of Zoology at Louisiana State University. These five
specimens are assigned to H. h. concavus and resemble in every
way this subspecies except: slightly smaller, somewhat darker, and
skull with lambdoidal crest less inclined forward. In the latter
feature, the single skull available seems to resemble most closely
that of H. h. hispidus. Unfortunately, all but one skull, that of a
subadult female, were destroyed in the field.
This is the first known record of this genus in Tamaulipas and
the most northern locality from which specimens have been taken.
At this latitude, the gopher appears to be restricted to the humid
belt on the east face of the Sierra Madre Oriental. These large
gophers were difficult to trap by ordinary means; Schaldach got
two by using large-sized Macabee traps but the others were taken
at night either with the aid of a dog or by natives with slingshots.
Liomys irroratus texensis Merriam
Spiny Pocket Mouse
Liomys texensis Merriam, Proc. Biol. Soc. Washington, 15:44, March 5,
1902. (Type from Brownsville, Cameron County, Texas.)
Liomys irroratus texensis Goldman, N. Amer. Fauna, 34:59, September 7,
1911.
Specimens examined, 15 as follows: 7 km. S and 2 km. W San Fernando,
8; 36 km. N and 10 km. W Ciudad Victoria, 1 km. E El Barretal, on Río Purificacíon,
1; 70 km. [by highway] S Ciudad Victoria and 2 km. W El Carrizo, 6.
Remarks.—Most of these mice were taken in densely vegetated
fallow fields, where both grass and brush were found. Many of
the mice were captured at their burrow openings, some of which
were found to be plugged and others not plugged.
Reithrodontomys fulvescens intermedius Allen
Fulvous Harvest Mouse
Reithrodontomys mexicanus intermedius Allen, Bull. Amer. Mus. Nat. Hist.,
7:136, May 21, 1895. (Type from Brownsville, Cameron County, Texas.)
Reithrodontomys fulvescens intermedius Howell, N. Amer. Fauna, 36:47,
June 5, 1914.
Specimen examined, 1 from 70 km. [by highway] S Ciudad Victoria and
2 km. W El Carrizo.
Baiomys taylori taylori (Thomas)
Pygmy Mouse
Hesperomys (Vesperimus) taylori Thomas, Ann. and Mag. Nat. Hist, ser. 5,
19:66, January, 1887. (Type from San Diego, Duval County, Texas.)
Baiomys taylori Mearns, Mamm. Mex. Bound., Bull. 56:381, April 13, 1907.
[Pg 213]
Specimens examined, 2 from 70 km. [by highway] S Ciudad Victoria and
2 km. W El Carrizo.
Remarks.—Specimens were captured in runways in dense grass and weeds
at the edge of a corn field.
Peromyscus leucopus texanus (Woodhouse)
White-footed Mouse
Hesperomys texana Woodhouse, Proc. Acad. Nat. Sci. Philadelphia, 6:242,
1853. (Type probably from the vicinity of Mason, Mason County, Texas.)
Peromyscus leucopus texanus Osgood, N. Amer. Fauna, 28:127, April 17,
1909.
Specimens examined, 8 as follows: 7 km. S and 2 km. W San Fernando, 1;
12 km. N and 4 km. W Ciudad Victoria, 2; 70 km. [by highway] S Ciudad
Victoria and 2 km. W El Carrizo, 4.
Peromyscus ochraventer new species
Brown-bellied Wood Mouse
Type.—Female, adult, skin and skull; no. 36958, Univ. Kansas Mus. Nat.
Hist.; 70 km. [by highway] S Ciudad Victoria and 6 km. W of the [Pan-American]
highway [at El Carrizo], Tamaulipas, Mexico; 12 January 1950; obtained
by William J. Schaldach, Jr., original no. 566.
Range.—Known only from the type locality; probably found in other localities
along the humid, east face of the Sierra Madre Oriental in Tamaulipas.
Diagnosis.—Size medium (see measurements); upper parts near Ochraceous
Tawny (capitalized color terms after Ridgway, Color Standards and Color
Nomenclature, Washington, D. C., 1912), brighter on sides and duller on back;
cheeks, sides of neck, shoulders and upper forelegs lighter, between Ochraceous
Buff and Ochraceous Orange; eye ring dark; underparts light Cinnamon Buff,
breast patch brighter; ears dusky, sparsely covered with hairs colored like back;
feet white; tail scaly in appearance, indistinctly bicolored with short dark hairs
above and short pale hairs below; skull without beaded or ridged supraorbital
border; rostrum expanded anteriorly with sides almost parallel; teeth with
strongly developed outer accessory cusps on the first and second upper molar
teeth; anteriormost loph (parastyle-protoconule of Goldman, N. Amer. Fauna,
43:11, September 23, 1918) of the first upper molar large, almost as broad as
greatest breadth of tooth.
Comparisons.—Peromyscus ochraventer has been compared with P. difficilis
(specimens from Veracruz), P. boylei (Veracruz), P. banderanus (Guerrero),
P. mexicanus (Veracruz), P. furvus (Veracruz), and P. latirostris (San Luis
Potosí). From P. difficilis, P. ochraventer differs in having underparts distinctively
brownish, rostrum expanded anteriorly with sides almost parallel,
anteriormost loph of the first upper molar larger, and auditory bulla smaller.
From P. boylei, P. ochraventer differs in having underparts distinctively brownish,
tail less distinctly bicolored, rostrum expanded anteriorly with sides almost
parallel, and anteriormost loph of the first upper molar larger. From P. banderanus,
P. ochraventer differs in having underparts distinctively brownish, tail
less distinctly bicolored, rostrum expanded anteriorly with sides almost parallel,[Pg 214]
anteriormost loph of the first upper molar larger, auditory bulla smaller, and
in lacking a beaded or ridged supraorbital border. From P. mexicanus, P.
ochraventer differs in having underparts distinctively brownish, tail not irregularly
blotched with dusky, rostrum expanded anteriorly with sides almost
parallel, anteriormost loph of the first upper molar larger, and in lacking a
beaded or ridged supraorbital border. From P. furvus and P. latirostris, P.
ochraventer differs in being smaller, having underparts distinctively brownish,
tail not irregularly blotched with dusky, rostrum proportionately shorter, and
interpterygoid space relatively narrower.
Remarks.—Peromyscus ochraventer is considered to be a distinct
species showing little evident relationship with other Mexican
Peromyscus. In the shape of the skull, especially the anterior expansion
of the rostrum, P. ochraventer seems to be related to P.
furvus and P. latirostris, a series of the latter being made available
for examination by Dr. George G. Lowery, Jr., of the Museum of
Zoology at Louisiana State University. However, the rostrum of
these two larger species is proportionately longer than the rostrum
of P. ochraventer. In size, coloration and most cranial features,
P. ochraventer resembles P. mexicanus, although the absence, instead
of presence, of a supraorbital bead or ridge, the almost parallel-sided,
instead of more pointed, rostrum and the larger, instead
of smaller, interiormost loph of the first upper molar in P. ochraventer
are well-marked differences. The baculum of P. ochraventer
is much shorter with a proportionately heavier base and shaft than
the baculum of P. mexicanus mexicanus (from Veracruz) and P. m.
saxatilis (from Costa Rica). The geographic range of Peromyscus
ochraventer is not known to meet that of P. mexicanus; the nearest
place to the type locality of P. ochraventer from which P. mexicanus
has been taken is at Xilitla approximately 225 kilometers to the
southward in San Luis Potosí (Dalquest, Occ. Papers Mus. Zool.,
Louisiana State Univ., No. 28:8, July 10, 1950).
The brown coloring on the underparts is a distinctive feature of
P. ochraventer; in adults this color differs in shade. In some specimens
patches of whitish hair give the tail a splotched appearance.
Eleven of the twenty-eight skulls and lower jaws examined have
bone eroded away from around the cheek-teeth exposing part of
the roots. Most of the fully adult animals have this condition. One
adult female, no. 36959, has the upper third molar on the right side
missing, possibly as a result of bone erosion.
These mice were taken in junglelike forest, in rocks and adjacent
to logs. Schaldach writes that "Their burrows go back under the[Pg 215]
large limestone blocks, and each burrow where I caught a mouse
has a pile of excavated earth, like a tiny gopher mound." The
trapping area was at an elevation of approximately 2800 feet on the
steep sides of a small hill on top of which the field camp was situated.
Schaldach indicated that this locality was transitional between
arid tropical and humid tropical conditions. On January 13,
1950, a female taken was lactating and had five recent placental
scars; another taken the same day also had five placental scars.
Measurements.—Average and extreme measurements of seven adult males
and six adult females of P. ochraventer from the type locality are, respectively,
as follows: Total length, 238.0 (227-249), 236.5 (226-248); length of tail,
124.4 (117-127), 122.2 (116-128); length of hind foot, 25.6 (24-26), 25.5
(25-26); length of ear from notch, 20.9 (20-21), 20.7 (20-21); greatest length
of skull, 31.0 (30.6-31.9), 30.8 (30.5-31.0); basilar length, 23.3 (22.7-23.8),
23.4 (23.0-23.9); zygomatic breadth, 15.1 (14.6-15.7), 15.0 (14.9-15.2); post
palatal length, 10.6 (10.5-10.9), 10.9 (10.5-11.2); interorbital breadth, 4.7
(4.5-4.9), 4.7 (4.6-4.8); mastoidal breadth, 12.8 (12.4-13.2), 12.8 (12.6-12.9);
length of nasals, 11.6 (10.8-12.0), 11.6 (11.2-11.7); length of shelf of bony
palate, 4.7 (4.5-4.8), 4.6 (4.5-4.7); length of palatine slits, 6.3 (6.0-6.5), 6.2
(6.0-6.4); length of diastema, 8.2 (8.0-8.5), 8.2 (8.1-8.4); alveolar length of
upper molariform tooth-row, 4.4 (4.3-4.6), 4.4 (4.3-4.5).
Specimens examined, 28, from the type locality.
Oryzomys couesi aquaticus Allen
Coues Rice Rat
Oryzomys aquaticus Allen, Bull. Amer. Mus. Nat. Hist., 3:289, June 30,
1891. (Type from Brownsville, Cameron County, Texas.)
Oryzomys couesi aquaticus Goldman, N. Amer. Fauna, 43:39, September
23, 1918.
Specimens examined, 2 as follows: 36 km. N and 10 km. W Ciudad Victoria,
1 km. E El Barretal, on Río Purificacíon, 1; 70 km. [by highway] S
Ciudad Victoria and 6 km. W of the [Pan-American] highway [at El Carrizo],
1.
Remarks.—The specimens, all immatures, are slightly darker than
topotypes of O. c. aquaticus, seemingly tending toward the darker
O. c. peragrus Merriam to the southward. These records of occurrence
extend the known range of this subspecies approximately 210
miles to the southward and increase the possibility of continuous
distribution between O. c. aquaticus and O. c. peragrus.
The male obtained south of Ciudad Victoria was taken on January
12, by William J. Shaldach, Jr., 200 yards within the tunnel of a
mine at an elevation of approximately 2600 feet. This was in the
Sierra Gorda, which is a part of the Sierra Madre Oriental.
[Pg 216]
Oryzomys rostratus rostratus Merriam
Rice Rat
Oryzomys rostratus Merriam, Proc. Washington Acad. Sci., 3:293, July 26,
1901. (Type from Metlaltoyuca, Pueblo, Mexico.)
Specimen examined, 1 from 70 km. [by highway] S Ciudad Victoria and 2
km. W El Carrizo.
Remarks.—This immature male is paler than specimens of O. r.
rostratus from the state of Veracruz. This locality extends the
known range of this species northward a distance of approximately
100 miles. Previously it had been recorded from only as far north
as Alta Mira, Tamaulipas (Goldman, N. Amer. Fauna, 43:54, September
23, 1918). This specimen was trapped on February 16
in a rodent runway in dense grass in a fallow cane field.
Oryzomys fulvescens engraciae Osgood
Fulvous Rice Rat
Oryzomys fulvescens engraciae Osgood, Jour. Mamm., 26:300, November
14, 1945. (Type from Hacienda Santa Engracia, northwest of Ciudad Victoria,
Tamaulipas, Mexico.)
Specimens examined, 5 from 70 km. [by highway] S Ciudad Victoria and
2 km. E El Carrizo.
Remarks.—These specimens are referred to O. f. engraciae on the
basis of their pale color and narrow interorbital space. They were
taken in runways in dense grass in fallow cane fields.
Sigmodon hispidus toltecus (Saussure)
Hispid Cotton Rat
[Hesperomys] toltecus Saussure, Revue et magasin de zoologie, ser. 2, 12:98,
1860. (Type from mountains of Veracruz, Mexico.)
Sigmodon hispidus toltecus Bailey, Proc. Biol. Soc. Washington, 15:110,
June 2, 1902.
Specimens examined, 23 as follows: 36 km. N and 10 km. W Ciudad Victoria,
1 km. E El Barretal, on Río Purificacíon, 1; 70 km. [by highway] S Ciudad
Victoria and 2 km. W El Carrizo, 22.
Remarks.—Among named kinds of Sigmodon this series most
closely approaches S. h. toltecus to the southward. The specimens
are slightly lighter in color of the upper parts than are examples of
this same subspecies from 8 km. NW of Potrero, Veracruz, but in
other ways are similar. The single specimen from 36 km. N and
10 km. W Ciudad Victoria is a skull only, but seems closest to S. h.
toltecus. As is often the case with collections of Sigmodon, this
series contains mostly immatures.
Cotton rats were found abundantly in cultivated areas. Local[Pg 217]
farmers stated that these rats were destructive to sugar cane by
girdling the stems one and one-half inches above the ground.
Neotoma micropus micropus Baird
Baird Wood Rat
Neotoma micropus Baird, Proc. Acad. Nat. Sci. Philadelphia, p. 333, April,
1855. (Type from Charco Escondido, Tamaulipas, Mexico.)
Specimens examined, 2 from 7 km. S and 2 km. W San Fernando.
Neotoma angustapalata new species
Tamaulipan Wood Rat
Type.—Male, subadult, skin and skull; No. 36976, Univ. Kansas Mus. Nat.
Hist.; 70 km. [by highway] S Ciudad Victoria and 6 km. W of the [Pan-American]
highway [at El Carrizo], Tamaulipas, Mexico; 14 January 1950;
obtained by William J. Schaldach, Jr., original no. 578.
Range.—Known only from the type locality; probably found in other localities
along the humid, east face of the Sierra Madre Oriental in Tamaulipas.
Diagnosis.—Size large (see measurements); upper parts dusky brown, paler
on sides, individual hairs on middle of back tipped with black or with Light
Pinkish Cinnamon (capitalized color term after Ridgway, Color Standards and
Color Nomenclature, Washington, D. C., 1912); head grayer especially on
cheeks; underparts dusky (dark bases of white-tipped hairs exposed), hairs on
throat and inguinal region of adult specimen white to base; outside of legs
dusky gray; tail scaly in appearance and sparsely covered with short, blackish
hairs above and short, whitish hairs below; skull with auditory bulla large;
external auditory meatus large; palatine region narrow; sides of interpterygoid
fossa concave and broadly excavated near posterior end of molariform tooth-rows.
Comparison.—Neotoma angustapalata has been compared with N. torquata
(specimens from Veracruz and Puebla), N. navus (Coahuila), N. mexicana
(New Mexico), N. micropus (Tamaulipas), N. albigula (Coahuila), N. ferruginea
(Jalisco), and N. distincta (from published description in Goldman,
N. Amer. Fauna, 31:64, October 19, 1910). Neotoma angustapalata differs
from N. micropus and N. albigula in having a deep, instead of a shallow,
anterointernal reentrant angle on the first upper molar and seems to belong to
the N. mexicana group of wood rats. Neotoma angustapalata differs from N.
navus, N. mexicana, N. torquata, and N. ferruginea in larger size, darker
underparts, tail with sparse, short hairs and scaly appearance, more broadly
concave sides of interpterygoid fossa at posterior end of molariform tooth-rows,
larger external auditory meatus, and narrower palatine breadth. Neotoma
angustapalata differs from the description of N. distincta in having a faintly
bicolored tail, no ochraceous pectoral band, broadly concave sides to interpterygoid
fossa, and narrower palatine breadth.
Remarks.—Neotoma angustapalata is represented by two specimens;
the type and another specimen, an adult male, no. 37062,
with skin and broken skull. The description takes into account[Pg 218]
both of these specimens. The most significant characteristics of
N. angustapalata are its scaly-appearing tail with short, sparse hairs,
dusky underparts, broadly concave sides of the interpterygoid fossa
at the posterior end of molariform tooth-rows, and the narrow palatine
breadth. Among named kinds of Neotoma, the newly named
species most closely resembles N. torquata and N. distincta; however,
it is geographically widely separated from these two species.
Neotoma navus of southeastern Coahuila is the only other member
of the N. mexicana group in northeastern Mexico.
These wood rats were taken in rocks and crevices at the base of
a small hill in thick vegetation growing in deep humus. Schaldach
termed the trapping site as "arid tropical tending toward humid
tropical".
Measurements.—The subadult, male holotype measures as follows: Total
length, 325; length of tail, 154; length of hind foot, 36; length of ear from
notch, 29; basilar length (of skull), 33.9; zygomatic breadth, 22.1; interorbital
breadth, 5.7; length of nasals, 15.2; length of incisive foramina, 8.7; length of
palatal bridge, 8.5; least breadth of palate between first upper molars, 2.7;
greatest breadth of interpterygoid space, 4.1; alveolar length of upper molariform
tooth-row, 9.6. The adult, male, no. 37062, measures as follows: Total
length, 380; tail vertebrae, 195; hind foot, 42; ear from notch, 31; interorbital
breadth (of skull), 6.4.
Specimens examined, 2, from the type locality.
Rattus rattus subsp.
Black Rat
Specimens taken, 2 from 70 km. [by highway] S Ciudad Victoria and 6 km.
W of the [Pan-American] highway [at El Carrizo].
Mus musculus subsp.
House Mouse
Specimen examined, 1 from 12 km. N and 4 km. W Ciudad Victoria.
Nasua narica tamaulipensis Goldman
Coati
Nasua narica tamaulipensis Goldman, Proc. Biol. Soc. Washington, 55:80,
June 25, 1942. (Type from Cerro de la Silla, near Monterrey, Nuevo Leon,
Mexico.)
Specimen examined, 1 from 70 km. [by highway] S Ciudad Victoria and
2 km. W El Carrizo.
Remarks.—Several bands of coatis were observed in the vicinity of the village
of El Carrizo. One skull of a male was obtained.
