BARBASTELLA

to at least 8000 feet (Blanford). It is said to have a larger ear 

 and longer forearm (44.5 mm.) than barbastellus. Satunin's 

 sub-species caspica (forearm about 43 mm.), described from 

 Transcaucasia, is not available for examination. The genus is 

 unknown in America. 



The generic characters are moderate size ; ears not large, their 

 bases united at their inner margins on the forehead, their outer 

 margins encircling the eyes and terminating between them and 

 the upper lips ; a well-developed tragus 

 with an attenuated tip. 



The short muzzle (Plate XIV., Figs. 



2 and 3) has the upper surface naked and 

 nearly flat dorsally, the sides glandular 

 and tumid so as to form a raised border : 

 the nostril is terminal, with a broad shal- 

 low groove running across the upper lip. 



The moderately broad wing (Plate 

 XVII., Fig. 2) arises from the base of 

 the toes. The calcar extends about 

 half-way from foot to tail. The post- 

 calcarial lobe is narrow and incon- 

 spicuous. The tail is nearly as long as 

 the head and body ; its tip projects about 



3 mm. from the interfemoral membrane, 

 which is ample, Supported by long lower 

 legs, and extends triangularly to some 

 distance behind the feeble feet. 



The skull (Fig. 8, No. 5, p. loi), as 

 exemplified by B. barbastellus, is weak, 

 with prominent rounded brain-case ; 

 broad, somewhat concave facial region ; 

 weak, flattened zygomata ; weak or no cranial crests ; and 

 moderately developed auditory bullae. 



There are thirty-four teeth (Figs. 21 and 22) arranged as —
