Our next three drawings are of a smaller size and 

 more delicate form, and would approach nearer to 

 the type of that figured by D'Orbigny as S. margi- 

 natus ; one, indeed, is somewhat allied to that fish, 

 but is much deeper, and wants the rich black bor- 

 der fringing the anal fin, though it possesses the 

 red band within it. As a contrast, it may stand 

 now as 



RED-BORDERED SAW-BELLIED SALMON. 



Salmo enoarginatus. 



PLATE XIX. 



Schomb. Drawings, No. 72, 



No notes accompany this figure. The dorsal out- 

 line is very irregular from the insertion of the first 

 dorsal fin to the commencement of the caudal fin. 

 The head is proportionally small. The body above 

 the lateral line is bluish grey, becoming paler to- 

 wards the line ; below, it shades to white or silvery.
