2. PTEPvOPUS. 15 



double the length of the muzzle, shaped as hi E.gamhianus ; nostrils 

 rather widely separated, the shaUow emargination between them 

 continuous with a groove dividing the lower lip ; lips thickened 

 near the extremity of the muzzle and folded near the angle of the 

 mouth. 



'^^'ings from the base of the second toe ; tail extremely short and 

 thin *. 



Fur yellowish brown above ; beneath, paler brown, the extremi- 

 ties of the hairs greyish. The wing-membrane is covered almost as 

 far outwards as a line drawn from the elbow to the knee, also the 

 humerus and three fourths the forearm and the legs as far as the 

 ankles ; the feet are naked. 



The palate is very peculiarly marked, and quite on a different 

 plan from that of any other species of the genus. A broad but shaUow 

 Y-shaped groove is formed by -the union of two grooves, each com- 

 mencing opposite the single premolar on each side, and uniting in 

 the centre and continued backwards as a single central groove which 

 terminates in the vaulted roof of the palate behind. (Plate II. 

 fig. 6.)

Hah. West Africa (Yoruba, Gambia, Lagos, Gaboon). 



This and the preceding species approach the species of Cynmiycteris 

 and Cynopterus more closely than others in the shape of the head ; 

 indeed, dried skins appear at first sight to belong to species of these 

 genera.

Muzzle long, narrow, and cylindrical ; nostrils projecting by their 

 inner margins, the extremity of the muzzle deeply emarginate 

 between them ; upper lip with a vertical groove in front, bounded 

 laterally by rounded naked ridges ; second finger with a distinct 

 claw ; metacarpal bone of the middle finger shorter than the second 



* Hitherto I have found no male of this species among the different speci- 

 mens examined by me, and consequently I am unable to state whether shoulder- 

 pouches exist or not.
