HYDROCYON, Cuvier. 

 In Hydrocjon of Cuvier, * several modifications 

 of form seem to occur, no less than five being no- 

 ticed and referred to particular types of fishes : — 

 1. Salmo falcatus^ Blocli. ; 2. Charcxinus Amazoni- 

 cus, Spix, XXXV. ; 3. Cynodon viilp'mus^ Spix, xxvi. ; 

 4. Xiphostoma ; 5. Characinus dentex, Geof. The 

 genus, therefore, would scarcely appear to be well 

 defined, and we place our present drawing under it 

 as approaching nearest in form to those species 

 figured by D'Orbigny as 11. hepsetus, hiimeralis^ 

 &c. 



SMALL-SCALED HYDROCYON. 



Hydrocyon microlepis. 



Macusi, Ghawarrlkang. Schomh. Draivings^ No. 16. 



*' This fish is found in the Rios Negro and Branco, 

 as well as in the Essequibo. In the upper part of 

 the latter river they are very plentiful ; and when 

 the river is low, several hundreds are taken in a 

 night by placing a canoe across a small creek which.
