35° GAME FISH OF NORTH AMERICA. 



anterior ray of dorsal fin is in front of a point midway between the 

 pectorals and ventrals. Branchiae, 9 ; fin formula as follows : D. 

 24; A. 3-11; C. &-1S-7; P. 15; V. 10. 



Colcr. — Ashy grey with small bluish spots. Dorsal fin spotted. 

 Habitat, British America. Dall speaks of this species as being 

 abundant in the small rapid rivers of Alaska, and states moreover 

 that it is the only Yukon fish that will take the hook ; is abundant 

 in the spring. It is thought that almost any fly resembling the 

 natural ones of the locality will answer as bait ; for a showy lure a 

 piece of grayling fin will answer. 



MoDNTAlK "Grayling. — Tkymailus montaniu. Milner. 



Specific characters. — Form stouter than preceding species. 

 Depth of body gjreater than length of the head ; region of dorsal 

 fin anterior to a point midway between the pectorals and the ven- 

 trals. The body is deeper than in the other American species, the 

 length of the head is greater than that of T. signifer. The fork- 

 ing of the tail is less than in T. tricolor. 



Color. — Resembles somewhat preceding species, but the red 

 spots on the dorsal are semicircled by a thin border of emerald 

 green. The ventrals also show a shade of green, and the caudal 

 is plain in color. Habitat, Missouri River, Montana. 



The same methods of capture as advised for preceding species 

 may be employed for this.

 times ; mouth small and herring like ; diameter of eye enters 

 length of side of head five times ; anterior margin of dorsal fin

 Abundant in Provo and Sevier Rivers, Utah. They are taken in 

 November in great numbers with hook and line, and a certain mia- 

 new for bait, (Clinostoiiius tcenia) caUed " leatherside " by the 

 Mormon settlers. They bite well and freely, affording excellent 

 sport. A few are taken in Utah Lake by net, though seldom. In
