THE TSUPPITCH. 



Salmo Tsuppitch ; .

 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 vonier 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-

" 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.
