Scotophilus nigritellus^ sp. n. 



Size smaller than S. nigrita {S. borbonicus), but apparently 

 agreeing with that species in general form. The colour above 

 is dark olive, the bases of the fur lemon-yellow. This colour 

 is somewhat nearly matched in occasional specimens of both 

 S. nigrita and the Indian species 8. Kuhli; but size alone is 

 sufficient to distinguish it from either of these forms. 



The ears and tragus, also the teeth and skull, closely 

 resemble those of 8. nigrita^ but are very much smaller in 

 size. 



Type no. 99. 6. 15. 9 in British Museum.

Scotophilus hirundoj sp. n. 



Colour of the body above mouse-grey, beneath silvery 

 white; wings and interfemoral membrane wholly dark, with 

 perhaps the exception of the postcalcaneal lobe, which in the 

 dry skin appears pale grey. The tragus is short and

 species the dentition also closely agrees.
