General remarJcs. — Myotis lucifugns longicrus is a well-marked geo- 

 graphical race of i)A lucifugm^ replacing the typical form of the latter 

 in the western United States throughout the region west of the Great 

 Plains. The northern and southern limits of its range can not at pres- 

 ent be determined. 



A single skin from Oofre de Perote, Vera Cruz, is probably referable 

 to M. lucifugns longicrus. The tibia, however, is slightly shorter than 

 in true longicrus, and more material from southern localities may show 

 the necessity of recognizing another geographic race. 



Myotis lucifugus longicrus is the bat to which the 'melanic form of 

 Vespertilio albescens^ of Dr. Allen's recent monograph for the most part 

 refers. Under this name, however, Dr. Allen also included dark- 

 colored specimens of M, californiciis.
