=Lasiurus borealis mexica.n.u.s= (Saussure)

_A[talapha]. mexicana_ Saussure, Rev. et Mag. de Zool., 13(2):97, March, 1861, type probably from Veracruz, Puebla or Oaxaca.

_Specimen examined_, 1: no. 89446, Univ. Michigan, Mus. Zool., 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. mexica.n.u.s_ 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.
