I40 VESPERTILIONID^— MYOTIS 



It ranges from southern Sweden to Dalmatia, and from 

 France to Asia, and is, perhaps, representative of the American 

 genus Lasionycteris. 



The rich tints of this species, dark brown marbled with 

 pale yellowish brown, and the strongly contrasted whitish under- 

 parts, make it one of the most beautiful of European bats. 

 It may be at once distinguished from the Serotine by its colour 

 and smaller size, the forearm measuring only about 43-45 

 mm. From Nilsson's Bat also it differs in colour, the latter 

 being deep brown grizzled with tawny above and yellowish 

 brown beneath, in its slightly larger size, the forearm of the 

 latter averaging 39-45 mm., and in having the tragus broadest 

 above, instead of below, the middle of the inner margin.]
