4. Bahardar. — ^Degen. 



This species, which may be regarded as intermediate between JB. bt/nni&nd JB. affinis^ 

 was founded on two specimens forming part of Mr. Degen's Abyssinian collection. 

 The larger was obtained in the Mogre River, a tributary of the Blue Nile, in Shoa, the 

 other at Bahardar, Lake Tsana. We have since received specimens from the Ergino 

 River (Omo system), from the Sagan River, connecting Lake Abaia with Lake 

 Stephanie, and from the Elgo River, flowing into Lake Abaia.
