FISHES. 



a.S Hemtchromis is not represented in the north-eastern parts of 

 Africa proper, but chiefly on the west coast and in the Central 

 African lakes. 



Madagascar clearly belongs to this region. Besides some 

 Gobies and Dules, which are not true freshwater fishes, four 

 Chromides are known. To judge from general accounts, its 

 Freshwater fauna is poorer than might be expected ; but, 

 singular as it may appear, collectors have hitherto paid but 

 little attention to the Freshwater fishes of this island. The 

 fishes found in the freshwaters of the Seychelles and Masca- 

 renes are brackish-water fishes, such as Fundulus, Hap- 

 lochilus, Mops, Mugil, etc.
