a. Four interdental and about live to seven iiost- 

 dental palate-ridges ; three anterior interdental 

 ridges thick, prominent, quite or nearly straight;, 

 the'^first and second always undivided in middle ; 

 fourth interdental and all postdeutal ridges 

 thinner, serrate, more or less arcuate or angular 

 (figs. 31 A, B). 

 a'. Third interdental palate-ridge nearly always 



undivided in middle (fig. 31 A); bony palate 



flatter ; zygomatic breadth about three-fifths 



of total length of skull ; skull, total length 



46-8-53 mm. (males) and 41-8-47 (females), 



forearm 88-96 (males) and 82-93 (females).

 (Synonyms under the subspecies,) 



CAaraciers.— Palate - ridges as described and figured p. 489, 

 fig. 31 A. The ridges have been examined in 24 individuals 

 representing both subspecies and from the following localities: — 

 Gold Coast (two), Togo (one), Lagos (one), South Nigeria (four), 

 Cameroons (nine), Spanish Guinea (one), Gaboon (two), Malandje 

 (one), Tingasi (one), uncertain localities (two). In 23 of these the 

 third'interdental ridge is practically undivided in the middle, either 

 absolutely continuous or, not infrequently, with a distinct notch at 

 the middle suggesting an initial stage toward a splitting of the 

 ridge ; in one single individual the ridge is distinctly divided in 

 the middle, by a space about equal to the breadth of p' (Kradji, 

 Togo, collected by Count Zech, Berlin Museum 8945, with skull

 andantero-posteriorly than in E. huettikoferi ; rostrum and palate 

 relatively shorter ; zygomatic breadth about three-fifths of total 

 len-^th of skull. Size smaller than E. huettihoferi, a difference much
