724 MR. G. E. DOBSON ON THE MOLOSSI. [Nov. 7, 



neath, less white at the base of the hairs, but slightly greyish at tbe 

 tips. 



Distribution of the fur upon the wing-membrane as in N. cestoni ; 

 a narrow band of short hairs behind tbe anterior two thirds of the 

 forearm on the upper surface. 



In J a thick tuft of long bairs arises from the back of the deep 

 band connecting tbe ears ; in $ this hair is not longer than on tbe 

 adjoining inner sides of the backs of the ears. 



Lower incisors very small, crowded ; first upper premolar minute, 

 with an acute cusp, iu the centre of the space between the canine 

 and second premolar. 



Length (of an adult J): head and body 2 "'1 ; tail 1"'25, tail 

 free from membrane 0"*75 ; head 0''*8; ear 0""65, tragus O" - x 1 

 0"03; forearm 1"'5 ; thumb 0""7; second finger — metacarp. 1""4, 

 1st ph. 0"*G, 2nd ph. 0"*7 ; third finger — metacarp. 1"*35, 1st

 0""4, 2nd ph. 0"*2 ; tibia 0"'5 ; foot and claws 0*25.

 p. 337. 



This form can be distinguished from N. pumilus only by the 

 different colour of the fur of the ventral surface and of the wing- 

 membranes, and by tbe slightly broader tragus. In every other 

 respect it agrees so perfectly in structure and measurements with 

 that species, that I can scarcely consider it specifically distinct. 



Fur above dark brown, also the shoulders, throat, and upper 

 part of the breast; the remaining parts of the ventral surface pale 

 yellowish white, and the wing, antebrachial, and inferior surface 

 of tbe interfemoral membrane of the same colour. In immature in- 

 dividuals the white colour of the ventral surface is not so much ex- 

 tended, but appears as a more or less broad patch on the abdomen, 

 increasing in extent according to age. 



Hab. Africa, south of the Equator (Zanzibar, Mozambique, An- 

 gola) ; Madagascar. 



This appears to be the southern representative of N. pumilus. 



10. Nyctinomus angolensis. 



Nyctinomus angolensis, Peters, Jorn. Scien. Mathem. Phys. e 

 Natur. Lisboa, vol. iii. p. 124 (1870). 



Ears much shorter and more triangular than in any of the species 

 previously described, conjoined on the muzzle by a very deep band, 

 as in N. pumilus ; the antitragus and keel of the ear-conch as in that 

 species; integument of tbe ears thick; tragus very small, quadrate, 

 superior margin directed upwards and outwards. Upper lip remark- 

 ably thick in front, so that the extremity of the nose does not pro- 

 ject much beyond its margin, its sides grooved by vertical furrows.
