Basicranial axis only slightly deflected : alveolar line pro- 

 jected backward passing through middle of external auditory 

 meatus. Tympanic not produced into a bony auditory 

 meatus. Rostrum shortened, owing to enlargement of orbital 

 cavity : front of orbit vertically above back of p\ Pre-

 (when unworn) bifid, p^ in cross section subequal to an upper 

 incisor, m^ and m-^ rudimentary, m^ much reduced in size 

 (from one fourth to somewhat less than half the bulk of mi).

Matschic^s Myonycteris. — Myonycteris in its original sense 

 (a subgenus of Xantharpyia ; Matschie, I, s. c.) included two 

 species, M, torquata {\. q. collar is -, the type) and M. angol- 

 ensis. But angolensis is a true Rousettus, whereas coUarisy 

 as being in skull and teeth more closely related to Cynopterus
