4. Kerivoula lanosa. 



Fespertilio lanosus. Smith, 111. Zool. S. x\frica, pi. 50. 



This species presents precisely the same generic peculiarities which 

 characterize the foregoing, and they are quite as typically developed. 

 It possesses the same elevated crown and small muzzle, and has ears 

 and tragi of a similar shape, the diflFerences being only such as are 

 purely specific ; but these differences, taken in the latter sense, are 

 very conspicuous. Whilst the fur is relatively as long as that noticed 

 of K. jiapi^losa, it is, in addition to that, very thick and curly, with 

 the tips very glossy. 



But it is necessaiy first to notice some other slight diflFerences 

 which exist in the form of the ears and the distribution of the fur. 

 The ears, although of the same general form as those of K. picfa 

 and the other species here treated of, yet differ in being more deeply 

 notched externally towards the tip. 



The tragus is of the same tapering and pointed form observable 

 in the other species. 



The face is very hairy, in some examples excessively so, the fur 

 of the forehead almost concealing the ears ; and it is of the same soft 

 quality as that on the to]) of the head and on the back, a small 

 quantity only in front of the eye assuming a more bristly appear- 

 ance. The ears have their hinder surfaces clothed with hairs, and 

 when viewed from behind are scarcely visible. The fur of the back 

 does not encroach on the membranes of the vdngs, but extends over 

 the base of the interfemoral membrane for nearly half its length, 

 and, thinning out, leaves the hinder half naked. The upper sur- 

 faces of the tail, feet, tibiae, fore-arms, thumbs and index-fingers 

 are garnished with short and shinmg hairs of a silvery or pale 

 golden-yellow colour. 



The hinder margin of the interfemoral membrane, between the as 

 calcis and tail, is furnished with a very remarkable comb-like fringe 

 of prominent thick-set hairs, which, curving dow^nwards, have their 

 points directed towards the belly of the animal. On all the upper 

 parts the fur is tricoloured, with a faint indication of a fourth colour. 

 At the root it is blackish-grey for nearly half its length, which is 

 succeeded by palish-brown, and this again for a very short length of 

 a darker tint, and finally tipped with sulphur-yellow. The latter 

 colour is on the head, neck, and shoulders so pale as to give a silver)^ 

 appearance to the tips of the hairs, which is heightened by their 

 being curly, somewhat as in the fur of the common Hare. Towards 

 the hinder parts they are less curly, and more yellow in colour, 

 esj)ecially those which grow on the legs, tail, and interfemoral mem- 

 brane. The same may be said of those on the upper surface of the 

 fore-arms, thumbs, and index-fingers. 



Beneath, the fur is bicoloured, dark at the base, with the terminal 

 fourth whitish-grey, very much as in the common Fespertilio mysta- 

 cinus ; but the light- coloured tips are more shining than in that 

 species. 



The membranes are of a medium brown colour, somewhat diapha-
