The Recent Mammals Of Tamaulipas, Mexico Part 7

Novit., 1670:1, June 28, type from Rancho del Cielo, 5 mi.

NW Gomez Farias, 3500 ft., Tamaulipas.

_Distribution in Tamaulipas._--Known only from the type locality and vicinity thereof.

This subspecies is known only from two complete specimens, six crania and four rami collected in two different localities--the type locality and Aserradero del Infernillo, only seven kilometers from the type locality. All the specimens were examined and reported by Goodwin (1954:1; 1954:4). The type specimen "was taken in a low section of an overgrown ditch" and the other complete specimen was trapped in a stone wall that separated an orchard from a pasture. The six skulls were found in owl pellets.

=Notiosorex crawfordi= (Coues)

Crawford's Desert Shrew

1877. _Sorex (Notiosorex) crawfordi_ Coues, Bull. U. S.

Geol. and Geog. Surv. Territories, 3:651, May 15, type from near old Fort Bliss, approximately 2 mi. above El Paso, El Paso Co., Texas.

1895. _Notiosorex crawfordi_, Merriam, N. Amer. Fauna, 10:32, Dec. 31.

_Distribution in Tamaulipas_.--Known only from two localities in southwestern part of state.

The two specimens examined were collected in July, one in tropical forest and the other in pine-oak forest; each was a lactating female and each weighed 5 grams.

Judging from Merriam's (1895:32) description, the two females differ from the type and three specimens from San Diego, Texas, in having a unicolored tail and in being slightly larger externally. When more abundant material is available the _Notiosorex crawfordi_ of northeastern Mexico probably will be found to represent a new subspecies; for the present I follow Findley (1955:616) in referring Tamaulipan specimens to _N. crawfordi_.

_Measurements._--External measurements of the specimens from Jaumave and Palmillas, respectively: 90, 90; 28, 31; 11, 11.5; 8, 8. For cranial measurements see Findley (1955:32).

_Records of occurrence._--Specimens examined, 2: Jaumave, 2400 ft., 1; Palmillas, 4400 ft., 1.

=Scalopus inflatus= Jackson

Tamaulipan Mole

1914. _Scalopus inflatus_ Jackson, Proc. Biol. Soc.

Was.h.i.+ngton, 27:21, February 2, type from Tamaulipas, 45 miles from Brownsville, Texas.

_Distribution in Tamaulipas._--Known only from the type locality.

_Scalopus inflatus_ is known only from the type specimen, which is imperfect and lacks complete data according to Jackson (1914:21). The type locality is in Tamaulipas, 45 miles from Brownsville, Texas, but the exact direction from Brownsville is unknown; probably the locality was on the road between that town and San Fernando, Tamaulipas, which is south-southwest of Brownsville.

=Pteronotus rubiginosus mexica.n.u.s= (Miller)

Mustached Bat

1902. _Chilonycteris mexicana_ Miller, Proc. Acad. Nat. Sci.

Philadelphia, 54:401, September 12, type from San Blas, Nayarit.

_Distribution in Tamaulipas._--Southern part of state in areas of tropical forest.

Most individuals of this species were taken in mist nets. Northwest of El Encino for example, bats were collected from a net placed in "a strategic position across a narrow opening" (Schaldach, fieldnotes) in a cave near the headwaters of the Rio Sabinas; along the same river at Rancho Pano Ayuctle some were taken in a net stretched across a little creek (arroyo). In the cave near El Encino the collector (Schaldach) estimated the population of _P. rubiginosus_ at between two and three hundred; at Ojo de Agua this bat was found in the deepest part of a cave in a.s.sociation with _Myotis nigricans_.

Two June-taken females from the Sierra de Tamaulipas were lactating, and weighed 17 and 18 grams.

The generic name _Pteronotus_ is employed instead of _Chilonycteris_ following Burt and Stirton (1961:24-25). The specific name _rubiginosus_ is used in accordance with de la Torre (1955:696).

Tamaulipan specimens are a.s.signed to _P. r. mexicana_ because they do not differ from specimens of that subspecies from Nayarit, except that the coloration of Tamaulipan specimens averages slightly darker in both color phases.

Specimens of this subspecies from the Sierra de Tamaulipas, previously recorded by Anderson (1956:349), are the northernmost reported in eastern Mexico.

_Records of occurrence._--Specimens examined, 31: Sierra de Tamaulipas, 2 mi. S, 10 mi. W Piedra, 1200 ft., 1; Sierra de Tamaulipas, 3 mi. S, 10 mi. W Piedra, 1400 ft., 3; Rancho Pano Ayuctle, 25 mi. N El Mante, 3 mi. W Pan-American Highway, 300 ft., 3; Ojo de Agua, 20 mi. N El Mante, and 3 km. W Pan-American Highway, 300 ft., 2; 10 km. N, 8 km. W El Encino, 400 ft., 22.

Additional records (Goodwin, 1954:4): Aserradero del Paraiso; El Pachon.

=Pteronotus davyi fulvus= (Thomas)

Davy's Naked-backed Bat

1892. _Chilonycteris davyi fulvus_ Thomas, Ann. Mag. Nat.

Hist., ser. 6, 10:410, November, type from Las Penas, Jalisco.

1912. _Pteronotus davyi fulvus_, Miller, Bull. U. S. Nat.

Mus., 79:33, December 31.

_Distribution in Tamaulipas._--Known only from the two localities reported in this paper.

According to field-notes of Schaldach _et al._, individuals of _P. d.

fulvus_ appear when it is almost dark (about 6:30 p. m. in December and January), ordinarily fly about 25 feet above the ground, but occasionally are seen at heights of between 60 and 70 feet (near tops of the largest cypress trees). Most bats flew in a straight line for 10 to 20 yards, then zig-zagged, and repeated the same movements. All specimens examined are in the brown color phase.

_Records of occurrence._--Specimens examined, 11: Rancho Santa Rosa, 25 km. N, 13 km. W Cd. Victoria, 260 m., 10; Rancho Pano Ayuctle, 6 mi. N Gomez Farias, 300 ft., 1.

=Ch.o.e.ronycteris mexicana= Tschudi

Mexican Long-tongued Bat

1844. _Ch.o.e.ronycteris mexicana_ Tschudi, Untersuchungen uber die fauna Peruana ..., p. 72, type from Mexico.

_Distribution in Tamaulipas._--East side of Sierra Madre in southwestern part of state.

Specimens from La Mula were obtained in a small cave, which was inhabited also by _Desmodus rotundus_ and _Tadarida brasiliensis_. The specimens from Miquihuana were captured in a mine by a native. Those from four kilometers north of Joya Verde also were taken from a mine.

Females obtained in August at La Mula were lactating.

Specimens examined are indistinguishable from _C. mexicana_ from Oaxaca and Jalisco. Baker (1956:172) found no differences between Coahuilan and Tamaulipan specimens. Most Tamaulipan specimens are dark grayish, but some are brownish and some are intermediate between the two colors mentioned. Fourteen adults weighed an average of 16.0 (12-18) grams.

_Records of occurrence._--Specimens examined, 19: 4 km. N Joya Verde, 4000 ft., 3; La Mula, 13 mi. N Jaumave, 4; Cueva La Mula, 10 km. W Joya Verde, 2400 ft., 2; Miquihuana, 6500 ft., 10.
