Range.—Probably statewide.
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.

Hoary Bat; Spanish, Murciélago Pardo
Vespertilio cinereus (misspelled linereus) Beauvois, Catal. Raisonné Mus. Peale, Philadelphia, p. 18, 1796, type locality, Philadelphia, Pennsylvania.
