 MALACOPTERYGII. SALMONID/E. 



THE TSUPPITCH. 



Salmo Tsuppitch; 



" ' The Tsuppitct ascends the Columbia at the same time with the 

 Ekewan. I counted 1644 ova in the ovary of a female. 



" ' Color. — Back of body and head studded with oval and circular 

 spots ; sides and fins, including the caudal, destitute of spots ; back 

 medially bluish gray, passing on the back of the head into blackish 

 gray, and on the sides into yellowish gray, with a greenish tinge and 

 silvery white. General color of the fins ash gray. Teeth, — Jaws 

 fully armed with minute sharp teeth, a single row on each palate bone, 

 a very few on the anterior end of the vomer in a single series, and a 

 double row on the tongue. Form. — Head small, exactly conical, ter- 

 minating in a pointed snout. Commissure of mouth very slightly ob- 

 lique. Convexity of dorsal profile rising gradually to origin of first 

 dorsal, and declining from thence to the tail. Caudal forked. Rays 

 —Br. 13; P. 13; V. 10; A. 13; D. 12—0.' 



" A spine containing sixty-four vertebrae, and an under jaw with ten 

 curved teeth in each limb, are all the bones that I can with any ap- 

 pearance of correctness refer to this species. The teeth are of equal 

 size with those of S. Gairdneri, or perhaps rather larger, and are at- 

 tached to the jaw-bone through the medium of cartilage.
