Remarks—The fur of this bat is distributed as in Myotis yuman- 
ensis yumanensis. On the back the distal portion of the fur is isabella 
color and on the belly it is a pale tint of light buff. The skull differs 
considerably from skulls of other races of Myotis yumanensis from 
California. In addition to the greater size of the cranium, the brain- 
case is more inflated, and at the same time the depression between the 
brain-case and rostrum (in altipetens) is less marked than in the other 
subspecies.
