Scotophilus nigriteUuSj sp. n. 



Size smaller than S. nigrita [S. borhonicus)y but apparently 

 agreeing with that species in general form. The colour above 

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

 is somewhat nearly matched in occasional specimens of both 

 S. nigrita and the Indian species S. 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 IS. nigrita ^ but are very much smaller in 

 size. 



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

Scotophilus kirundo, sp. n.
