2i2 VESPEBTILIONIDiE. 



47. Vesperugo blanfordi. 



Vesperugo (Hesperopteuus) blanfordi, Dobson, Journ. Asiat. Soc. 

 Bengal, 1877, p. 312. 



Head very flat and broad ; muzzle obtusely conical ; nostrils 

 opening widely apart by semilunate apertures, the margins of whicli 

 are level with the extremity of the muzzle ; ears short, triangular 

 in outline, with broadly rounded-oii tips ; upper half of the outer 

 margin of the ear-conch straight, then convex, slightly concave 

 opposite the base of the tragus, terminating abruptly in a deep lobe 

 closer to the angle of the mouth than to the base of the tragus ; 

 tragus narrowest opposite the base of its inner margin, expanded 

 above and curved inwards. Thumb short, with a very acute claw ; 

 a broad adhesive cushion occupies the base of the inferior surface of 

 the metacarpal hone, and extends outwards and backwards upon the 

 base of the metacarpal of the second finger. 



Feet very small, the solo of the foot apparently adhesive, but not 

 expanded as in V. pachypus ; postcalcaneal lobe remarkably large 

 (probably proportionately larger than in any other sj)ecies of Bat) 

 and broader than the foot, with a central cartilaginous prop ; the 

 extreme tip of the tail alone projecting. 



Pur dark reddish brown above, slightly paler beneath. 



Penis with a distinct hone, in shape quite similar to that of F". 

 ticTcelli, and with a similar prepuce. 



Dentition almost quite similar to that of V. ticlcelli, the outer 

 upper incisors are even smaller and placed more behind the inner 

 incisors ; the inner incisors unicuspidate and very acutely pointed ; 

 lower incisors trifid and placed in the direction of the jaws ; the 

 single upper premolar close to the canine ; the first lower premolar 

 with a very short and obtuse cusp, the second equals three fourths 

 the canine in vertical extent. 



Length, head and body l"-75, tail 1""1, head 0""6, ear 0""45, tragus 

 0"-18, forearm 1""1, thumb 0"'15 ; third finger — metacarp. 1", 1st 

 ph. 0"-6, 2nd ph. 0"-6 ; fourth finger— metacarp. 1", 1st ph. 0"-53, 

 2nd ph. 0"-28 ; fifth finger— metacarp. 0"-95, 1st ph. 0"-35, 2nd ph. 

 0"-22 ; tibia 0"-45, foot 0"-25. 



Hah. Tonasserim. 



This species is about the size oi Vesperugo minutus, Temm., from 

 South Africa, and is therefore one of the smallest species of the 

 genus. It is not half the size of V. ticJceHi, with which it agrees 

 in other respects so closely. Its resemblance to that species in the 

 position of the upper outer incisors and in the form of the penis, 

 which has a distinct bone, is verj^ remarkable. The single type 

 specimen (an adult male in excellent preservation) was sent to me 

 by Mr. AV. T. Blanford, F.E.S., and is now in the collection of the 

 Indian Museum, Calcutta.
