Wings to the base of tlio toes. Post-calcareal lobule very 

 narrow. Tip of tail Httle projecting. 



Skull, as compared witii that of P. nanus, similar in size, 

 but with a broader, flatter muzzle and smaller brain-case. 

 Median palatal spine less developed. Base of skull between 

 bulla? conspicuously narrower. 



Incisors slender, conical, unicuspid terminally, though each 

 lias a minute basal cusplet on its cingulum behind ; the outer 

 two thirds the height of the inner. Small upper premolar 

 unusually minute, hidden in the inner angle between the 

 closely adpressed canine and large premolar, and lower than 

 their cingula, so as to be quite invisible from without. 

 Lower incisors trifid, overlapping, subequal in horizontal 

 length, but the outer pair slightly thicker than the others. 

 Anterior lower premolar two thirds the height of the second, 

 small in section, the canine and large premolar almost touching 

 each other on its inner side.

'Jype. Adult female. Original number 28. Collected 

 12tli August, li)03. Two specimens. 



This most interesting little bat is widely different from 

 any species yet described, the proportions of its upper incisors 

 distinguishing it at once from most members of the genus. 

 ]ts anterior upper premolars are so minute that they would 

 probably be overlooked by any worker only examining spirit- 

 specimens; but there is no recorded " l^espertilio" of so small 

 a size in Egypt. 



DipodtUus MachiUighu, sp. n. 



A pencil-tailed species similar to D. famuhis, Thos., but
