HTPSIGNATHUS. 501 



individuals (specimens b and c, infra) are similar to pale-coloured 

 specimens of E. franqueii. 



Measurements. On pp. 509, 511, 513. 



Specimens examined. Those catalogued below. 



Range. Benguela, east to Katanga. 



Type, an adult male from Quindumbo, Benguela, in the Lisbon 

 Museum. Palate-ridges figured by Bocage, I. e. 



Remarhs. — This species is probably a southern representative of 

 E. buettikoferi, with peculiarly modified palate-ridges and somewhat 

 weaker dentition. In the cranial characters, at any rate, it more 

 closely approaches E. buettikoferi than it does E. franqueii.

Differential characters. — Allied to Epomops, but cranial rostrum 

 greatly enlarged, particularly in depth (dorsal and ventral profiles 

 subparaUel in adult males), extremity of rostrum, premaxillte, and 

 mandibular symphysis much broader, postdental palate narrower ; 

 lower incisors not (or indistinctly) bilobed and closing in front of 

 upper incisors, lower canines slanted considerably outward and 

 closing some distance in front of upper canines, p, rudimentary, 

 outer ridge of lower molars bilobed or trilobed ; 15 thoracic, 

 3 lumbar, no postsacral vertebrce ; upper lip with conspicuous 

 intogumeutary folds, ears pointed. Males larger than females, 



* Murray probably originally intended to name this genus Zygisnocepkaltis 

 in allusion to the Hammer-headed Sharks {Zyy<f7ia), and had that name 

 printed on the plate, but for some reason or other changed it in the text to 

 Sphyrocepkdltis.
