NO. 1199. CRUSTACEANS OF WEST AFRICA— EATHBVN. :>91 



{^^ Neptunus diacant/ms^^) from Ogowe, West Africa, and Bahia, Brazil.^ 

 It is impossible to tell without examination of specimens whether these 

 so-called "iV^. diacanthus^^ are synonymous with G. hocourti or with other 

 species of CalUnectes. 



Eochebrune says of Neptunus amnicola, which I think may be identi- 

 cal with CalUnectes hocourti, that it is found only in the fresh waters of 

 rivers and is much sought after for food, the meat being exceptionally 

 good. The negroes fish for them to eat and to sell to the Europeans. 

 The Ouolofs call it "koti."
