_Specimens examined_, 4: nos. 11377, Univ. Kan., and alcoholic specimens nos. 950-952 B. Villa R. field numbers, I. B. (specimens in Instituto de Biología, Univ. de México), distributed by localities as follows: Hacienda El Sabino, Michoacán, approximately 25 mi. S Uruapan, 1; El Guayabo, 34 kms. S Uruapan, 3. _Remarks._--Specimens from El Guayabo were taken in a natural cave which they shared with _Desmodus rotundus murinus_ and _Artibeus planirostris planirostris_. * * * * * The length of the thumb averages 7.4 mm. (7.0 to 7.7). As compared with _G. s. alticola_ from northeast Tlaxcala according to the description given by Davis (1944:377), our specimens agree with _alticola_ in length of thumb. In all other characters they correspond to _leachii_. =Choeronycteris mexicana= Tschudi Long-tongued Bat; Spanish, Murciélago Carilargo _Choeronycteris mexicana_ Tschudi, Fauna Peruana, p. 72, 1844, type from México. _Range._--Statewide. _Specimens examined_, 4: nos. 100078-100081, from 2 mi. W Pátzcuaro, 7,700 ft. _Remarks._--A colony of 20 or more bats of this species was found in a natural cave. Four were caught by hand as they flew about after we disturbed them. We returned on the following day, but found that all the bats had left. =Leptonycteris nivalis nivalis= (Saussure) Leaf-nosed Bat; Spanish, Murciélago Lengüilarga _M[=Ischnoglossa]. nivalis_ Saussure, Revue et Magasin de Zoölogie, 12(ser. 2):492, November, 1860, type from near snow line on Mount Orizaba. _Leptonycteris nivalis_, Miller, Proc. Biol. Soc. Washington, 13:126, April 6, 1900. _Range._--Probably middle and higher altitudes through state. _Specimen examined_, 1: no. 91911, Univ. Michigan Mus. Zoöl., from 1050 m., 12 miles (on Huetamo Road) south of Tzitzio. _Remarks._--The subspecific name _L. n. nivalis_ is tentatively applied to this specimen in the absence of an opportunity to compare it directly with the holotype or topotypes of _Leptonycteris nivalis yerbabuenae_ Martinez and Villa (1940:291). Unfortunately, the materials on which this name, _L. n. yerbabuenae_, was based all were destroyed in 1945 or 1946 while Villa was absent from the Institute of Biology of the University of México. =Artibeus planirostris planirostris= (Spix) Big Leaf-nosed Bat; Spanish, Murciélago Zapotero _Phyllostoma planirostre_ Spix, Simiarum et vespertilionum Brasiliensium, p. 66, 1823, type from suburbs of Bahia, Brazil. _Artibeus planirostris_, Dobson, Catal. Chiroptera, British Mus., p. 515 (part), 1878. _Range._--Probably southwestern part of state. _Specimen examined_, 1: no. 945b B. Villa R., field no., I.B., El Guayabo, 34 kms. S Uruapan.
