o86 Mr, K. Andersen on 



Posterior connecting-process very short, rounded off above, 

 scarcely projecting beyond the summit of sella (this kept in 

 vertical position). Margins of lancet abruptly narrowed ; 

 tip of lancet behind constriction with slightly converging 

 (nearly parallel) margins, about 2 mm. in length. 



Ears. — Large ; reaching far beyond the tip of the muzzle, 

 when placed along the sides of the head. Tip of ears 

 obtusely pointed, as in Rh. capeyisis. Outer margin strongly 

 concave below tip. Notch on outer margin shallow, obtuse. 

 Extreme width of ear somewhat greater than the distance 

 from notch to tip. 



Wings. — General form as in Bh.capensi.tj but all dimensions 

 markedly smaller. 4th metacarpal slightly longer than 5th. 

 In the folded wing the tip of the 1st joint of 4th finger 

 reaches very nearly the posterior point of the elbow; tip of 

 1st joints of 3rd and 5th fingers slightly beyond. Plagio- 

 patagium inserted at basal joint. 



Tail. — Considerably longer than in Bk. capensis, uro- 

 patagium therefore much broader. Hinder margin of 

 uropatagium, between tips of calcars, square (concave in 

 Bk. capensis, on account of the shorter tail). Tip of tail 

 projecting about 1 mm. 



Colour (1 skin). — Exactly as in Bh. axigur. Length of 

 hairs on middle of back about 8 mm. Young individuals 

 (1 skin) considerably duller than adult ones; details exactly 

 as in Bh. augur, juv. 



Skull. — Very diflferent from that of Bh. capensis : — Much 

 smaller. Nasal swellings unusually prominent; nasal region 

 deejjly hollowed out behind swellings ; for both these reasons 

 the facial portion of the skull, from the swellings to crista 

 sagittalis, more concave than in Bh. capensis. Palatal bridge 

 much broader : median anterior point opposite front of m^, 

 in Bh. capensis opposite middle of the same molar. 



Dentition. — Widely different from that of Rh. capensis : — 

 Distance between tips of upper canines 3'8 mm., in Bh. 

 capensis 5 mm. Upper canine and p'^ distinctly separated 

 from each other, also internally ; distance between tips of 

 these teeth 2"1 mm. ; in Bh. capensis, although the skull 

 is much larger, 1"9 mm. Upper j9^ placed in the tooth-row, 

 with a minute cusp distinctly projecting above the cingulum 

 of canine. Highest cusp of p' somewhat more than half the 

 height of canine. Inner lobes of molars less developed than 

 in Rh. capensis : ni' as long as broad, in Rh. capensis 

 decidedly broader than long. Kight ps extremely minute, 

 in the outer angle formed by the cingula of p2 ^^^ P^ 5
