Diagnosis. — Epomophorine section (incisors^ — ^, cheek-teeth^ 

 exterual tail rudimentary, small whitish hair-tufts at base of 

 ears anteriorly and posteriorly, males with shoulder-pouches 

 and "epaulettes"). Cranial rostrum short and broad, almost 

 Cynopteriue, palate very broad between m'-m\ abruptlj' narrowed 

 behind zygomatic processes, maxillary tooth-rows extending back- 

 ward nearly to orbital cavity, postdental palate depressed posteriori}', 

 palation rim prominent, palate-ridges peculiar (see tig. 39). General 

 size small, forearm about 50-53 mm. [One species. Range, the 

 whole of the western Ethio[>ian forest region.] 



Skull (fig. 3S). — Length of rostrum (front of orbit to tip of 

 nasals) subequal to breadth across lower edges of lachrymal foramina. 

 Interdental palate broad, maxillary tooth-rows strongly diverging 

 antero-posteriorly, breadth between postero-internal corners of 

 m^-m' much more than twice the breadth between bases of canines ; 

 maxillary tooth-rows extending backward very nearly to ventral 

 margin of orbital cavity ; palate abruptly narrowed immediately 

 behind zygomatic processes of maxillaries, breadth of ])ostdental 

 palate at middle therefore slightly less than (or at most equal to) its 

 length and only about three-fourths of breadth between m'-m' ; 

 postdental palate distinctly dejjressed posteriorly, hinder edge raised 

 and prominent (compare Epomoplwrus), lateral edges subparallel, 

 mesopterygoid fossa broad. Premaxillse in contact anteriorly but 

 not fused, tapering above to a recurved point. Brain-case flattened 

 (Epomophorine), basicranial axis only slightly deflected against 

 facial axis. Temporal ridges rather broadly separated (no sagittal 

 crest), postorbital much greater than interorbital breadth, zygomata 

 deeper at middle than anteriorly and posteriorly, zygomatic processes 

 of squamosals nearly horizontal (not drawn upward in a strong 

 curve b}' fascia temporalis), postorbital processes short and thin. 

 ]lami of mandible slender, coronoid rather broad but low and 

 sloi)ing, angular process weak and broadly rounded off, condyle 

 distinctly above level of alveolar line.
