were then aware it did not differ from P. nanus, but our attention was 

 drawn to two bugs (family Cimicidse) clinging to its wing membranes. 



34. Scotozous ruppelii (Fischer). 



Creamy white on the under side and mouse-gray above, these are the 

 characteristic colors of this pretty species. The dark obtuse muzzle is 

 nearly hidden in the long fur of the head, from which the slightly elongate 

 but rounded ears stand out laterally. The total length of this male is 3.2 

 inches (82 mm.), the wings when folded are pale brown, but when fully opened 

 appear nearly transparent and measure 8.25 inches (209 mm.) across. 



Like Scoteinus schlicffenii it has a large external penis, a half inch long, 

 covered with short white hair directed basally, with a penial bone a quarter 

 of an inch in length; the testes are placed laterally to the tail behind the 

 anus. 



Several of these bats were fluttering about the oil palms at Poko on 

 the Bomokandi River, but this male entered a lighted room and could then 

 be easily caught. It was known to occur on the mainland opposite Zanzibar, 

 northward to Egypt and westward to Lake Albert. Its discovery at Poko 

 in the Uele district thus extends its range considerably to the westward. 



35. Eptesicus tenuipinnis (Peters). 



A very small brown bat with filmy white wings, actually transparent. 

 Total length, about 2.8 inches (72 mm.), tail 1.14 inches (29 mm.), spread 

 of wings 7.25 inches (184 mm.). Fur of upper surface mummy-brown, 

 sometimes tipped with whitish, that of lower surface dark brown basally, 

 but with whitish ends so that the abdomen appears nearly white. The 

 muzzle is decidedly swollen laterally, and its skin in life is yellowish pink, 

 but whiter just around the nostrils. Ears, wing and tail membranes, as 

 well as claws, metacarpals, and phalanges white; arms and feet dark pink. 



Although distributed from Lagos and other parts of West Africa east- 

 ward to Lake Victoria, this strikingly colored little bat came to our notice 

 but once, at Ngayu in the Ituri forest. A hollow tree was cut down, in 

 which seven of them were found hanging. 



36. Eptesicus ater sp. nov. 



Similar to the preceding species but darker — fur of the back brownish 

 black — and slightly smaller: total length 2.7 inches (68 mm.), tail 1.15 

 inches (29 mm.), expanse of wings about 7.15 inches (182 mm.). The wing
