shows that 53 are adult females and the rest young animals, males 

 and females in about equal proportions, most of them nearly full 

 grown but with the metacarpal epiphyses still showing immaturity. 

 No adult males had as yet joined the colony. Under natural condi- 

 tions this is doubtless a cave-haunting species. Myotis thysamodes 

 seems to be less common or at least more sporadic than Myotis velifevj 

 for though the two animals occur over much the same general area, 

 collections contain far fewer examples of this species than of the 

 latter.
