all like it are V. vagans, Dobs.*, and, in a much lesser degree, 

 V. maurus, Bias. ; but these species have a very different 

 dentition, possessing a minute first upper premolar and other 

 characters of the subgenus Vesperugo. 



Kerivoula Smitliii. 



Ears of medium length, laid forward they extend about one 

 tenth of an inch beyond the end of the muzzle ; inner margin 

 very strongly convex, its centre being over a point halfway 

 between the eye and the tip of the nose ; outer margin with a 

 deep emargination j ust below the tip. Tragus slender, tapering, 

 with a very small triangular lobule at 

 the base, succeeded above by a shal- 

 low emargination, as shown in the 

 woodcut ; from the angle above this 

 emargination the sides slope evenly 

 to the tip, which is acutely pointed. 

 Fur, above and below, greyish 

 brown, the tips of the hairs shining 

 grey. 



Wings to the base of the toes. 

 Distribution of fur much as in A", lanosa, Sm., with the exception 

 of the marginal fringe to the interfemoral, of which there is 

 no trace in this species. 



Inner upper incisors long, with a distinct posterior secondary 

 cusp at a point about two thirds of their height ; the outer 

 upper incisors just equal the secondary cusp of the inner inci- 

 sors, and have also a distinct internal posterior secondary 

 cusp, whose tip is about half as high as the main cusp ; upper 

 premolars bearing the usual proportions to each other, the 

 third being the largest and the second the smallest, the first 

 being just intermediate in size. First and second lower 

 incisors trilobate, outer ones unicuspidate ; lower premolars 

 equal. 



Length (of the type, an adult male, in spirit) — head and 

 body l"-55, tail 1"7, head 0"-58, ear 0""55, tragus 0"-3, fore- 

 arm l"-3, thumb 0"'27, third finger 2""7, fifth finger 1"- 9, 

 tibia 0"-55, foot 0"-25. 



This species belongs to Dr. Dobson's second section of the 

 genus t, characterized by the presence of a basal lobe to the 

 tragus ; this lobe, however, is very small as compared with 

 that of the other species of the section. 



In addition to the characters of the tragus, which might
