sembling in different degrees that which is seen in the American 

 evotls and thysanodes occurs in at least six Old World species; 

 hechsteinii^ emarginatus^ my st acinus^ nattereri^ 7nifopicttis, and #n- 

 coJor. The extreme type of reduction we have seen in the myotis 

 group only {blythii, cMnensis, 7nyotis, oxygriathus). This group, 

 apparently, is not connected by intermediate stages of structure with 

 any other members of the genus. It might, therefore, be separated 

 as a subgenus or genus Myotis in the restricted sense. The name 

 Leucono'e Boie would then be available for the great mass of species 

 now called Myotis. At present, however, we are not convinced of 

 the desirability of following this course, as the Old World members 

 of the genus are still insufficiently known.
