298 VESPERTILIOXIDJE. 



0-7, forearm 1-65 (Hutton's measurements of, I believe, this indi- 

 vidual when fresh are larger; head and body 2|, &<?.) 



Distribution. The Palaearctic region, including the higher portions 

 of the Himalayas from Grilgit (Scully) and Leh (Stoliczka) to 

 Darjiling. The Himalayan variety has rather longer ears than the 

 European, but the short thumb, observed by Dobson in Hodgson's 

 type of P. homochrous, appears to be an individual peculiarity, as it 

 does not exist in other Himalayan specimens. 



Habits. The long-eared bat, according to Blasius, hides in hollow 

 trees or old buildings (probably in caves also) during the day and 

 comes out rather late in the evening. The flight is not rapid, but 

 the twists and turns are quickly made. This species only flies in 

 the summer months, hibernating in the winter. The ears are 

 usually folded under the arms during sleep. 



Genus SYNOTUS, Keys. & Bias. (1839). 

 Syn. Barbastellus, Gray, 1838 (nee 1831). 



Ears of moderate size, the inner margins coming forward at 

 the forehead rather in front of the eyes and united at the base ; 

 the outer margin of each ear carried forward below the eye and 

 terminating between the eye and upper lip ; thus the eye, which 

 is minute, is within the external ear ; tragus well developed, atten- 

 uate above. 



Muzzle short, the upper surface naked and flat in the middle, 

 the sides glandular and swollen so as to form a raised border, the 

 nostrils at the end of the muzzle, a broad shallow groove from 

 each across the upper lip. 



Dentition : i. ~, c. ~J, pm. |^, m. |^|. Upper incisors 

 oblique, outer pair small, inner pair large and bifid ; upper canines 

 with small anterior and posterior basal cusps. First upper pre- 

 molar minute, in the inner angle between the closely approximate 

 canine and second premolar. First lower premolar half the height 

 and breadth of the second. 



This genus comprises two known species, both Palaearctic ; one 

 of them is found in the Himalayas.
