The Recent Mammals Of Tamaulipas, Mexico Part 13

=Nycticeius humeralis humeralis= (Rafinesque)

1818. _Vespertilio humeralis_ Rafinesque, Amer. Monthly Mag., 3(6):445, October, type from Kentucky.

1819. _N[ycticeius]. humeralis_ Rafinesque, Jour. Phys.

Chim. Hist. Nat. et Arts, Paris, 88:417, June.

_Distribution in Tamaulipas._--Matamoros (Miller, 1897:120), one specimen.

=Nycticeius humeralis mexica.n.u.s= Davis

1944. _Nycticeius humeralis mexica.n.u.s_ Davis, Jour. Mamm., 25:380, December 12, type from Rio Ramos, 1000 ft., 20 km.

NW Montemorelos, Nuevo Leon.

_Distribution in Tamaulipas._--Known certainly only from central part, but probably occurs at suitable places in all but extreme northern Tamaulipas.

Twenty-seven of 37 adults of _N. humeralis_ examined from Tamaulipas are pale as is _N. h. mexica.n.u.s_, but 10 are darker and approach _N. h.

humeralis_ in this respect. Twenty-two females averaged 10.3 (9-13) grams and eight males averaged 9.5 (8-11) grams in weight.

_Records of occurrence._--Specimens examined, 45: Cd.

Victoria, 10; Sierra de Tamaulipas, 2-3 mi. S, 10 mi. W Piedra, 1200 ft., 31; 3 mi. S, 16 mi. W Piedra, 1400 ft., 4.

=Rhogeessa tumida tumida= H. Allen

Little Yellow Bat

1866. _R[hogeessa]. tumida_ H. Allen, Proc. Acad. Nat. Sci.

Philadelphia, 18:286, type from Mirador, Veracruz.

_Distribution in Tamaulipas._--Southeastern part of state.

Specimens obtained from the vicinity of La Pesca were shot as were some from the Sierra de Tamaulipas. Others from the Sierra de Tamaulipas were taken in mist nets that were stretched across a small pool in an arroyo; _Eptesicus fuscus_, _Myotis velifer_, _M. keenii_ and _Nycticeus humeralis_ were captured in the same nets.

Females evidently bear young in Tamaulipas in April and May. Fourteen of 15 females collected at La Pesca in May were lactating, as were five of 31 taken in the Sierra de Tamaulipas in June. The weight of 46 females averaged 5.5 (4-7) grams, and that of nine males, 4.5 (4-5) grams.

Comparison of specimens from Tamaulipas with individuals from Veracruz reveals little difference in general color between the two samples.

Most Tamaulipan specimens examined are dull yellowish brown, but some are darker. Goodwin (1954:6) reported a specimen from Santa Maria as being dark brown. Measurements of 10 females (see below) from the Sierra de Tamaulipas average a little larger than those reported by Miller (1897:123-124), Hall (1952:232), and Goodwin (1958:10-12). I follow the last author in using the specific name _R. tumida_ for this bat.

_Measurements._--Average and extreme measurements of 10 females from the Sierra de Tamaulipas are as follows: 80.1 (78-83); 35.5 (33-37); 7.9 (7.5-8.0); 13.1 (13-14); length of forearm, 31.9 (30.6-33.0); greatest length of skull, 13.4 (13.1-13.8); zygomatic breadth, 8.6 (8.2-8.8); mastoid breadth, 5.6 (5.3-5.8); breadth across M3, 5.7 (5.5-6.0); length of maxillary tooth-row, 4.8 (4.7-4.9).

_Records of occurrence._--Specimens examined, 59: 4 mi. N La Pesca, 1; 3 mi. N La Pesca, 3; 2 mi. N La Pesca, 11; 1 mi. N La Pesca, 4; La Pesca, 1; Sierra de Tamaulipas, 2 mi. S, 10 mi. W Piedra, 1200 ft., 39.

Additional record: Santa Maria (Goodwin, 1958:3).

=Plecotus phyllotis= (G. M. Allen)

Allen's Big-eared Bat

1916. _Corynorhynus phyllotis_ G. M. Allen, Bull. Mus. Comp.

Zool., 60:352, April, type from San Luis Potosi, probably near city of same name.

1959. _Plecotus phyllotis_, Handley, Proc. U. S. Nat. Mus., 110:130, Sept. 3.

1923. _Idionycteris mexica.n.u.s_ Anthony, Amer. Mus. Novit., 54:1, January 17, type from Miquihuana, Tamaulipas.

_Distribution in Tamaulipas._--Known only from Miquihuana.

The only specimen of this bat known from Tamaulipas was reported by Anthony (1923:1), and formed the basis of his description of _Idionycteris mexica.n.u.s_, a synonym of _Plecotus phyllotis_ according to Handley (1956:53 and 1959:130).

=Antrozous pallidus pallidus= (Le Conte)

Pallid Bat

1856. _V[espertilio]. pallidus_ Le Conte, Proc. Acad. Nat Sci. Philadelphia, 7:437, type from El Paso, El Paso Co., Texas.

1864. _Antrozous pallidus_, H. Allen, Smiths. Misc. Coll., 7 (Publ. 165): 68, June.

_Distribution in Tamaulipas._--Known only from a single ramus from Aserradero del Infernillo (Goodwin, 1954:6).

=Tadarida brasiliensis mexicana= (Saussure)

Brazilian Free-tailed Bat

1860. _Molossus mexica.n.u.s_ Saussure, Revue et Mag. Zool., Paris, ser. 2, 12:283, July, type from Cofre de Perote, 13,000 ft., Veracruz.

1955. _Tadarida brasiliensis mexicana_, Schwartz, Jour.

Mamm., 36:108, February 28.

_Distribution in Tamaulipas._--Probably state-wide, but presently known from only five localities.

A female taken on June 21 in a mist net on the Sierra de Tamaulipas carried an embryo that was 29 mm. in crown-rump length. Two specimens were shot in flight in the deepest part of Cueva La Mula.

_Records of occurrence._--Specimens examined, 4: 8 km. S Cd.

Victoria, 1; Sierra de Tamaulipas, 10 mi. W, 2 mi. S Piedra, 1200 ft., 1; Cueva La Mula, 10 km. W Joya Verde, 2400 ft., 2.

Additional records: Rio Bravo (town) (Villa, 1956:8); Rancho "La Isla," 3 km. N El Limon (Malaga and Villa, 1957:560); Cueva del Abra (_ibid._); no specific locality (Shamel, 1931:6).
