338 YESPEBTILIOXIDyE. 



"Wings from the base of the outer toe; tail not projecting 

 beyond the interfemoral membrane. A small convex postcal- 

 caneal lobe. 



Second upper premolar slightly within the tooth-row, minute, 

 scarcely visible without a lens. 



Colour of the fur above black with pale tips ; below, basal 

 portion of the hairs black with ashy tips ; membranes intensely 

 black. 



Dimensions. Head and body 1'75 inches, tail 1*5, ear from 

 crown 0-42, forearm 1'3. 



Distribution. The greater portion of the Oriental region. In 

 the Himalayas this species has been found at Murree, Dalhousie, 

 Simla, and Mussoorie, in Nepal, and in Sikhim, at elevations up to 

 fully 8000 feet ; also at Calcutta, in Chutia Nagpur, in Ceylon, 

 Ara'kan, Tenasserim, and the Mergui Archipelago, and, outside 

 Indian limits, in Eastern Tibet, the Malay Peninsula, Java, Sumatra, 

 Borneo, and Celebes. 



No description of this bat was given by Hodgson, and Gray's was 

 imperfect, though it may be accepted, as a type exists in the 

 British Museum. 



Habits. According to Hutton," this bat is early on the wing, 

 coming out of caves and hollow trees, flying high, and is very 

 rapid in its movements. Like Vesperuyo micropus ( V. abramus), 

 when touched it opens the mouth wide, without emitting a sound, 

 or making the least attempt to escape or bite." 



Genus CERIVOULA, Gray (1842). 

 Syn. Kerivoula, Gray. 



Muzzle narrow ; skull concave between the nose and crown. 

 Glandular region between the eye and nose small, not prominent ; 

 mouth wide, the upper lip and angle of the mouth thickly fringed 

 with long hairs. Nostrils circular, opening sublaterally close to 

 the margin of the upper lip. Ears with the outer margin coining 

 forward, so as in great part to conceal the tragus when viewed from 

 the side, and terminating abruptly in a deep lobe, not separated 

 by a notch or concavity from the upper portion of the ear-margin, 

 nor carried forward to near the angle of the mouth ; ear-conch 

 thin, diaphanous, studded with glandular papillae, from which hairs 

 arise. Tragus extremely long, narrow, and acutely pointed. 

 Membranes of wings and interfemoral area largely developed ; 

 calcaneum long and strong, curved backwards ; no postcalcaueal 

 lobe ; tail equalling or exceeding the head and body in length. 



Dentition : i. -~?, c. g, pm. g, m. jg, as in Vespertilio, but 

 the upper incisors are parallel, not divergent, and the second 

 upper premolar, though smaller than the third, is never minute. 



This genus is essentially tropical, and inhabits the Oriental, 

 Ethiopian, and Australian regions. Three species are recorded 

 from British India and its dependencies.
