LIX. — Deso'iptions of new Fishes from the Collection made 

 hi/ Mr. E. Degen in Abyssinia. By G. A. Boulenger, 

 F.R.S. 



The splendid collection of Abyssinian fishes brought home 

 by Mr. E. Degen is one of exceptional interest from tiie fact 

 that it contains examples of every one of the species described 

 by Riippell in 1835*, of which only some of the types are 

 preserved, in a dry condition, in the Senckenberg Museum at 

 Frankfort a. M., and which had not been rediscovered since 

 the expedition of that illustrious zoologist and traveller ; and 

 that it has brought to our knowledge the existence in those 

 waters of a Loach, a group of which no African representa- 

 tive was on record, and of an astonishing multiplicity of species 

 of the genus Barbus, as well as of two new Silurids of the 

 genus Clarias. Twenty- one species are here described as 

 new ; fifteen of these belong to the section of which the 

 Nilotic Barbus bynni is the type and of which representatives 

 are known to occur in East and South Africa and in the 



* The material now available shows Varicorhinm beso, Riipp., to be 

 the same as the fish since described as Chondrostomn Dillo)ii, C. & V. 

 Gobio quadrimaculatus, Riipp., should bear the name Crossochiliis quadri- 

 maculatus, and Chondrostoma demheensis, Riipp., that of Dit^cor/nafhus 

 demheensis. Gobio liirticeps, Riipp., is not the male of G. quadrimacu- 

 latus, as sugfjested by Riippell, but of D. demhceyisis, the e^ye being situated 

 in th(! posterioi- half of the head.
