Diagnosis. — Allied to Natiomjcteris. Cranial rostrum short and 

 slender, postdental palate long with lateral margins forming straight 

 lines converging backwards, ma.xillary tooth-rows extending to 

 ventral margin of orbital cavity, premolars and molars unusually 

 short, oval or subcircular in transverse section, m' and m^ smaller 

 (in section) than respectively p* and p^ ; membranes from tirst toe, 

 head with conspicuous white markings, no tuft of white hairs at 

 base of ears. General size small, forearm 4S-5-.54 mm. [One 

 species. Hah. Cameroons and Fernando Po.] 



Skull (fig. 42). — In profile very similar to that of Nanonycteris 

 (fig. 40, p. 5(3o), upper protilo line conspicuously descending from 

 the top of the somewhat vaulted brain-case to the much lower 

 rostrum, llostrum as in JS'aiionycteris, only slightly shorter ])ro- 

 portionately, much lower and narrower than and not quite so short 

 us in Cynoplerus ; depth of face at centre of interocular region as 

 in 2\aiionyderis only equal to (in Cipiopterus much more than) 

 length of rostrum from orbit to nares; height of rostrum above 

 middle of alveolus of canine as in Nanonycteris rather less than 

 half (in Cynopteras three-fourths) the length of rostrum ; breadth 

 across alveolar margins at middle of diastemas c-p^ as in Xano- 

 iiyderis less (in Cyiiopterus more) than length of rostrum ; a 

 distinct postcanine constriction, as in Naiwnycferis. Xasal branches 

 of premaxilke subequal in breadth throughout (not tapering above) : 

 alveolar branches as usual in Megachiroptera in simple contact 

 anteriorly, but considerably deeper than in Sanonyderis ; plane of 

 their anterior surface not e.\actly vertical but (like the upper 

 incisors) distinctly retroclivous (see figure of lateral view of skull). 

 Maxillary tooth-rows more diverging antero-postcriorly than in 

 Nanonydei'is ; diastema c-p^ much wider, equal to the full (in 

 Nanonyderhi only to half the) space between bases of canines, and 

 the whole row of upper cheek-teeth more posterior in position, 

 extending nearly to (in Naaonycteris falling much short of) ventral 

 margin of orbit, and front margin of orbit vertically above front of
