Cretzschmar described this species from specimens obtained by Eiippell to the 
south-west of Ambukol. Hemprich and Ehrenberg had sent home specimens obtained 
in the province of Meroe to the Berlin Museum under the manuscript name of 
L. CBthiopicus ; and in writing the ‘ Symbolse Physicse,’ Dr. Ehrenberg adhered to that 
name, saying that probably the form described by Cretzschmar belonged to the same 
species. This question is not yet settled. 
Messrs. Eothschild and Wollaston obtained specimens of hares at Shendi from both 
sides of the river, which agree with Ehrenberg’s description and plate, but seem to 
differ from the diagnosis given by ■Cretzschmar. It is therefore desirable to have 
specimens of hares from the type locality before an opinion can be expressed.
