The Recent Mammals Of Tamaulipas, Mexico Part 8

1864. _Mormops megalophylla_ Peters, Monatsb. preuss. Akad.

Wiss., Berlin, p. 381, type from southern Mexico.

_Distribution in Tamaulipas._--Throughout state, except possibly west of the Sierra Madre Oriental.

Specimens from the Sierra de Tamaulipas were taken in mist nets in which _Pteronotus rubiginosus_, _Lasiurus borealis_, or _Centurio senex_ also were captured. The specimen from Rancho Santa Rosa was shot as it flew at a height of six feet.

Tamaulipan specimens of _Mormoops megalophylla_ are here a.s.signed to _M. m. megalophylla_ instead of to _M. m. senicula_ following Villa and Jimenez (1961:503), who regarded _senicula_ as indistinguishable from _megalophylla_.

Weight of four specimens from the Sierra de Tamaulipas averaged 16.2 (15-18) grams.

_Records of occurrence._--Specimens examined, 5: Sierra de Tamaulipas, 3 mi. S, 16 mi. W Piedra, 1300 ft., 2; Sierra de Tamaulipas, 3 mi. S, 14 mi. W Piedra, 1400 ft., 1; Sierra de Tamaulipas, 3 mi. S, 10 mi. W Piedra, 1400 ft., 1; Rancho Santa Rosa, 25 km. N, 13 km. W Cd. Victoria, 260 m., 1.

Additional records: Cueva de Los Troncones, 7.5 km. NNW, 3.5 km. S Cd. Victoria (Villa and Jimenez, 1961:503); Cueva de Quintero, 15 km. SSW Cd. Mante (_ibid._); Tampico (Davis and Carter, 1962:67).

=Micronycteris megalotis mexicana= Miller

Brazilian Small-eared Bat

1898. _Micronycteris megalotis mexicana_ Miller, Proc. Acad.

Nat. Sci. Philadelphia, 50:329, August 2, type from Platanar, Jalisco.

_Distribution in Tamaulipas._--Known only from Rancho Pano Ayuctle (Goodwin, 1954:4). The single specimen of this species presently known from Tamaulipas was shot while it was roosting in a ranch house.

=Glossophaga soricina leachii= (Gray)

Pallas' Long-tongued Bat

1844. _Monophyllus leachii_ Gray, _in_ The zoology of the voyage of H. M. S. Sulphur ..., 1 (1, Mamm.): 18, April, type from Realego, Chinandega, Nicaragua.

1913. _Glossophaga soricina leachii_, Miller, Proc. U. S.

Nat. Mus., 46:419, December 31.

_Distribution in Tamaulipas._--Tropical region of southern part of state.

Specimens from the Sierra de Tamaulipas were taken in a cave along with _Desmodus rotundus_ and _Tadarida laticaudata_. Specimens from 20 miles north of El Mante were collected from a cave about 50 yards deep.

Weights of two females from the Sierra de Tamaulipas were 9 and 12 grams. Tamaulipan specimens examined do not differ from specimens from Nicaragua that were used in comparison.

_Records of occurrence._--Specimens examined, 6: Sierra de Tamaulipas, 3 mi. S, 16 mi. W Piedra, 1400 ft., 2; 10 km. N, 8 km. W El Encino, 400 ft., 1; Ojo de Agua, 20 mi. N El Mante, and 3 km. W Highway, 300 ft., 2; 8 km. NE Antiguo Morelos, 500 ft., 1.

Additional records: 5 mi. NE Antiguo Morelos, near El Pachon (de la Torre, 1954:114); Altamira (Miller, 1913:420).

=Leptonycteris nivalis nivalis= (Saussure)

Long-nosed Bat

1860. _M. [= Ischnoglossa] nivalis_ Saussure, Revue et Mag.

Zool., Paris, ser. 2, 12:492, November, type from near snow line of Mt. Orizaba, Veracruz.

1900. _Leptonycteris nivalis_, Miller, Proc. Biol. Soc.

Was.h.i.+ngton, 13:126, April 6.

_Distribution in Tamaulipas._--Probably throughout southern part of state, but presently known only from one locality.

The specimens herein reported were taken in a cave. They provide the first record of the species from Tamaulipas and are a.s.signed to the subspecies _nivalis_ on the basis of their brownish color and small size in comparison with specimens of _L. n. longala_ from Coahuila (see also description and measurements of _longala_ given by Stains, 1957:356). None of the specimens suggests intergradation in color between _nivalis_ and _longala_, but some are slightly larger than specimens of the former from Veracruz.

Twelve females taken on August 27, 1961, were pregnant. Each carried a single embryo, the embryos averaging 15.7 (12-20) mm. in crown-rump length. The average weight of the 12 females was 26.9 (24.5-30.0) grams; 10 males weighed an average of 24.6 (21-28) grams.

_Measurements._--Average and extremes of ten specimens (5 males and 5 females) are as follows: 78.2 (76-80); 0.0; 16.4 (15-17); 16.7 (16-19); length of forearm, 48.4 (45.2-54.3); length of third finger, 100.8 (99.2-103.7); greatest length of skull, 26.8 (25.9-27.6); zygomatic breadth (6 only), 10.9 (10.7-11.1); least interorbital constriction, 4.6 (4.5-4.9); mastoid breadth, 10.8 (10.5-11.2); length of maxillary tooth-row, 8.7 (8.4-9.0).

_Records of occurrence._--Specimens examined, 28: all from 6.5 mi. N, 13 mi. W Jimenez, 1250 ft.

=Sturnira lilium parvidens= Goldman

Yellow-shouldered Bat

1917. _Sturnira lilium parvidens_ Goldman, Proc. Biol. Soc.

Was.h.i.+ngton, 30:116, May 23, type from Papayo, about 25 mi.

NW Acapulco, Guerrero.

_Distribution in Tamaulipas._--Known presently only from Rancho Pano Ayuctle.

The two specimens from Tamaulipas were reported by de la Torre (1954:114) and in eastern Mexico are the northernmost yet reported of the genus.

=Artibeus jamaicensis jamaicensis= Leach

Jamaican Fruit-eating Bat

1821. _Artibeus Jamaicensis_ Leach, Trans. Linn. Soc.

London, 13:75, type from Jamaica.

_Distribution in Tamaulipas._--Tropical region of southern part of state.

The specimens from northwest of El Encino were shot deep (250 yards) in a cave; specimens of _Myotis nigricans_ were obtained in the same cave.

A female taken on May 24 carried a single embryo that was 43 mm. in crown-rump length. Six March-taken females reported by de la Torre (1954:114) had one embryo each that varied from 20 to 38 mm. in length.

_Artibeus jamaicensis_ and _A. lituratus_ are the largest bats known from Tamaulipas. In addition to the differences between the two species pointed out by Lukens and Davis (1957:9), I note, in Tamaulipas at least, that the pos...o...b..tal constriction is narrower in relation to the condylobasal length in _lituratus_, 24.6 (23.7-26.0) per cent as compared to 27.9 (26.7-29.9) per cent in _jamaicensis_.

_Records of occurrence._--Specimens examined, 19: 10 km. N, 8 km. W El Encino, 400 ft., 10; Aserradero del Paraiso, 19 km. N Chamal (by road), 8 (AMNH); Cueva El Pachon, 5 mi. N Antiguo Morelos, 1 (AMNH).

Additional records: Rancho Pano Ayuctle (de la Torre, 1954:114); 4 mi. N Antiguo Morelos, near El Pachon (_ibid._).
