6. Salmo nitidus. (Richardson.) The Angmalook. 



Salmo nitidus. Richardson, Nat. Hist. 4pp. Ross's Voij., p. lvii. 

 Angmalook. Esquimaux. 



Plate 82, f. 1, one-third nat. size. Plate 86, f. 2, head of nat. size. 



This Char was found in the same lake with the preceding one, to which it is 

 similar in the size and form of its head, and in the general appearance of its scales. 

 If one may judge, however, from the inspection of a single prepared specimen of 

 each, it has a thicker body, shorter upper jaw, and shorter fins. It is possible that 

 these differences may be owing to age or individual variation, but the colours 

 appear also to be dissimilar : hence it seems safer to describe the angmalook as a 

 distinct species. 



DESCRIPTION. 



Form. — Back nearly straight as in S. alipes, but the body is thicker, the belly more pro- 

 minent, and the fins shorter. The middle of the tip of the snout and of the central caudal ray 

 falls under the ninth dorsal ray, and a very little posterior to the origin of the ventrals. The
