 lateral line and ventral fin, 12 or 14 round caudal peduncle. 



Silvery, back olive-brown (in spirit). 



14 specimens, measuring from 65 to 270 millimetres. 



Wabbi, Modjo, and Iraro Rivers.

15. Neobola bottegi Yincig. 



Several specimens from the Wabbi and Modjo Rivers, and from 

 the Omo River. 



The genus Neohola is very closely related to Chelcethiops, from 

 which it differs in the origin of the dorsal fin corresponding or 

 nearly corresponding to that of the anal, and in the absence of a 

 ventral keel. The snout of Neobola hottegi is shorter and moie 

 obtuse than that of GhelaitMoj)s bibie, and does not at all project 

 beyond the mouth ; the pectoral fin does not extend or extends 

 bvit very slightly beyond the root of the ventral. The largest 

 specimen collected by Mr. Neumann measures 73 millimetres.
