_Specimen examined_, 1: no. 91909, Univ. Michigan, Mus. Zoöl., from Rancho Escondido, one mile north of Apo, 6,000 feet elevation, June 29, 1947, female adult, taken by W. H. Burt. =Lasiurus borealis mexicanus= (Saussure) Red Bat; Spanish, Murciélago Rojizo _A[talapha]. mexicana_ Saussure, Rev. et Mag. de Zoöl., 13(2):97, March, 1861, type probably from Veracruz, Puebla or Oaxaca. _Lasiurus borealis mexicanus_, Miller, N. Amer. Fauna, 13:111, October 16, 1897. _Range._--Probably larger part of state. _Specimen examined_, 1: no. 89446, Univ. Michigan, Mus. Zoöl., from Nuevo San Juan (Los Conejos), 5 mi. SW Uruapan, May 23, 1945, by W. H. Burt. _Remarks._--This specimen, a male with much worn teeth, answers well to the description of _L. b. mexicanus_ except that the minute premolar between the canine and fourth premolar is missing on each side of the upper jaw. This, however, seems the less remarkable after examination of 18 skulls of _L. b. borealis_ from the United States in two of which these minute premolars are likewise absent; one of the two specimens from the United States has unworn teeth and the other much worn teeth. =Lasiurus cinereus cinereus= (Beauvois) Hoary Bat; Spanish, Murciélago Pardo _Vespertilio cinereus_ (misspelled _linereus_) Beauvois, Catal. Raisonné Mus. Peale, Philadelphia, p. 18, 1796, type locality, Philadelphia, Pennsylvania. _Lasiurus cinereus_, H. Allen, Monogr. N. Amer. Bats, Smithsonian Misc.

Fauna, 13:52, October 16, 1897. _Range._--Known from only Pátzcuaro. _Remarks._--Miller (1897:53) recorded one specimen from Pátzcuaro and Allen (1916:349) merely alludes to Miller's record. =Tadarida mexicana= (Saussure) Mexican Free-tailed Bat; Spanish, Murciélago Coludo _Molossus mexicanus_ Saussure, Rev. et Mag. de Zoöl., 12:283, July, 1860, type from Cofre de Perote, 13,000 feet, Veracruz. _Tadarida mexicana_, Miller, Bull.
