This species is allied to V. mawus, Bias., from whicli it may be distinguished, 

 however, by the absence of an emargination on the outer side of the ear, and 

 by the distribution of the fur. 



Sub-genus Vespeeus^ Keys, et Bias. 

 * Vespertjgo andersoni, Dobson, PL IV, iigs. 2, 6. ^ 



Vesperus andersoni, Dobson_, Proc. As. Soc. Bengal^ Sept. 1871^ p. 211. 



Head broad and flat ; muzzle thick ; nostrils opening sublaterally without inter- 

 vening emargination ; ears moderate with rounded tips ; inner margin convex, outer 

 with a shallow but wide emargination beneath the tip, then convex, and again emar- 

 ginate opposite the base of the tragus, terminating by forming a small lobe midway 

 between the base of the tragus and the angle of the mouth ; tragus obtusely pointed, 

 broadest in the middle, inner margin straight, outer with a small rounded lobe at the 

 base succeeded by a shallow emargination, then convex upwards to its junction with 

 the inner margin. 



Toes larger than half the whole foot ; tail of eight vertebrae, the last free. 



The fur of the body and head is moderately long and dense ; anteriorly it passes 

 forwards upon the face in front of the eyes as far as the commencement of the 

 glandular prominences of the upper lip, from which only a few long hairs arise ; that 

 portion of the face about the eye and in front of the base of the inner margin of 

 the ear is also naked, but the space between the base of the tragus and the angle of 

 the mouth is covered with long hair. In front the ears are naked, except where a 

 few very short hairs appear on the upper and inner side of the conch ; posteriorly, 

 the fur of the head encroaches on their bases, but more than one-half of their 

 posterior surfaces is naked. On the upper surface, the fur of the back extends upon 

 the wing-membrane as far as a line drawn from the junction of the proximal and 

 middle thirds of the humerus to the middle of the femur : posteriorly, it extends as 

 far only as the root of the tail, and the interf emoral membrane has but a few very 

 fine hairs dusted over its anterior surface, as far as the end of the second caudal ver- 

 tebrae. Beneath, the distribution of the fur on the wing-membranes is similar to that 

 on the upper surface, but somewhat more extended ; a line of fine thinly- spread hairs 

 passes out along the posterior margin of the humerus and forearm to the carpus ; 

 posteriorly, the fur of the abdomen covers the root of the tail only, and three-fourths 

 of the surface of the interfemoral membrane is occupied by a few, thinly spread, 

 very fine, minute hairs.
