to form a low sagittiil crest ; postnr'iital processes short and thin, 

 as in liousettiis. Tympanic ring relatively broad, as in Mousettus. 

 Rami of mandible very low, coronoid process low and much sloping, 

 angular process broadly rounded off, lower margin of rami deeply 

 concave in front of angidar process, condyle nearly at level of (in 

 £. dobsonl even slightly below) alveolar margin.

Upper incisors small, terete, generally narrowly spaced, and with

 from shaft, acutely pointed at tip, and often slightly recurved ;

E. franqueti and E. huetfikoferi: Four interdental and about 

 five to seven postdental ridges. Three anterior interdental ridges 

 thick and prominent, quite or approximately straight ; fourth 

 interdental and all postdental ridges thinner and serrate, more or 

 less arcuate or triangular; fourth interdental and anterior post- 

 dental ridges divided at middle, posterior postdental ridges often 

 conspicuouslj' asymmetric. Third iuteidental ridge in E. J'l-anqiieti 

 (A) nearly alwajs undivided at middle, though often with a 

 distinct median depression indicating a tendency to splitting : in 

 E. bneflikofcri (B) broadly divided at middle. 



E. dohsoni : Three thick and prominent interdental ridges, tlie 

 second very distinctly bifurcate at either extremity ; fourth and 

 fifth ridges postdental, thick and triangularly promirent ; one or 

 two thin and serrate ridges near posterior edge of palate.
