I have in a previous communication to the Society removed one 

 of these species — V. formosus — from the present genus, and placed 

 it in the group with the members of which its characters most closely 

 agree. After describing the species which I consider referable to 

 the genus Kerivoula, I shall enumerate such others as have been 

 called by that name, but which I consider as appertaining to other 

 groups. 



Fam. VespertilionidjE. 



Genus Kerivoula, Gray. 



Vespertilio, Pallas, Geoffroy, Desmarest, Fischer, Schreiber, 

 Wagner, Temminck. 



The top of the head is very much elevated, but not so much so 

 as in Furipterus, Natalus, and Miniopteris. The face is depressed ; 

 and the muzzle is of moderate length, and somewhat pointed. Tbe 

 nostrils, which are near together, open sublaterally, and have an 

 emarginate space between them. The lower lip has a tolerably well 

 defined naked triangular space in front. The ears are broad, with 

 the outer margin so much developed near the base as to form a com- 

 plete lobulus, which however is not separated from the upright part 

 of the ear by a notch or hollow, as in some species. The ear may, 

 indeed, be described as extending along the side of the face for some 

 distance, and in a line with the corner of the mouth, not as a narrow 

 strip of membrane, as in the generality of species, but ascending at 

 once from its most anterior point, and forming what is called the 

 ear-conch. Its inner margin is very ■convex, and curves off to the 

 tip of the ear, which terminates in an angular point not very acute. 

 In all the species there is a notch or hollow of more or less extent 

 in the outer margin, very near to the tip. 



The ear bears great resemblance to those of Furipterus and Na- 

 tahis, especially to those of the latter. The tragus is long, nearly 

 three-fourths the length of the ear, excessively narrow and pointed, 

 and a little curved outwards. Its outer margin near the base is 

 furnished with a projecting point or tooth. 



The tail is rather long, in some species as long as the head and 

 body. The wing-membranes extend to the base of the toes. The 

 feet are of medium size ; and the toes occupy a little more than 

 half the length of the foot. The thumb also is moderate ; and the 

 basal phalange, which is enclosed in the membrane, is shorter than 

 the remaining part. 



The membranes and ears of all the species are more or less dia- 

 phanous, and rather conspicuously marked with glandular dots ar- 

 ranged, on the former, in lines. 



The fur is of a fine woolly texture, in the Asiatic species without 

 lustre ; but in the African ones the hairs have shining tips. 



The skull does not, as might have been expected, exhibit any of 

 those peculiarities which are observable in the high-crowned genera, 

 such as Furipterus, Natahis, and Miniopteris. In its general ap- 

 pearance it somewhat resembles those of Vesp. mystacinus and
