700 Synopsis of the Vespertilionidte of Nipal. [Dec. 



constitute their sole food. They make their exit rather sooner than 

 the true bats, and always in considerable numbers. They are not 

 migratory, nor subject to hibernation. They breed once a year, 

 towards the close of summer, and produce two young, differing from 

 the parents chiefly in the very restricted development of the nasal 

 appendages. 



Pteropus. 

 * Ecaudatae. 



Pt. leucocephalus, mihi. Whole head and neck, with the body 

 below, rufous yellow ; face, as far as the eyes, the body above, and 

 the membranes, deep brown. Snout to rump, 10 inches. Expanse, 

 46. Weight, 22 oz. 



* Caudatas. 



Pt. pyrivorus, mihi. Wholly of an earthy brown ; nude skin of lips, 

 of joints, and of toes, fleshy gray ; tail very short, with its base enve- 

 loped in the interfemoral membrane, and its tip free. Snout to rump, 

 six inches ; tail, half an inch. Expanse, 24 inches. Weight, 5 oz. 



Remarks. — The Pteropi never appear in the central region of 

 Nipal, save in autumn, when they come in large bodies, to plunder 

 the ripe fruit in gardens. The lesser species is a perfect pest, from 

 the havoc it nrnkes amongst the ripe pears. Hence I have called 

 it pyrivorus. These animals are never seen in Central Nipal, save 

 at midnight, at which time they come to feed, and necessarily from 

 a very considerable distance. In the plains it is noted of them, that 

 they will travel 30 or 40 miles, and as many back, in the course of 

 a single night, in order to procure food.

V. formosa, mihi. Entirely cf a bright, soft, ruddy yellow, with 

 the digital membranes triangularly indented, blackish. Head, conical ;

V.fuliginosa, mihi. Wholly sooty brown. Ears, lips, and muzzle, 



as in the last : and face sharp, but the rostrum somewhat recurved, 



owing to the concave bend of the nasal bones, which in formosa are 



rather convex. Teeth ^ IX S"' In size somewhat less than 



formosa. 



V. labiata. Thick-lipped Bat, mihi. Head broad and depressed, 

 with a bluff physiognomy, and all the organs placed low down on the 

 sides of the head ; muzzle, small, clearly defined, rounded, grooved ; 

 lips very tumid, but not warty nor nude ; ears shorter than the head,
