FISHES OF THE SOUTHWEST 



SALMONID^. 



Rio Grande Trout. — Salmo spilurus. Cope. 



Specific characters. Head small, entering length of body 

 four times ; muzzle acute ; diameter of eye enters length of side of 

 head five times ; scales large, cranium not keeled above ; dorsal fin 

 nearer muzzle than end of caudal scales ; caudal scarcely emar- 

 ginate. Br. ix, ix. Color, lighter than S. pleuriticus which it re- 

 sembles ; yellowish-brown above, with small spots composed of 

 decussating lines. A red band on each side of the chin. 



Habitat, Head-waters of Rio Grande, New Mexico ; Sangre 

 de Christo Pass, Colorado ; and Brazos and Chama Rivers, New 

 Mexico. This species may eventually prove on further examina- 

 tion to be a well-marked variety of S, pleuriticus, this latter being 

 found in the same streams with it. 



As a game and food fish it cannot be surpassed ; biting readily 

 at either fly, grasshopper, grub, minnow or worm, it affords ex- 

 cellent sport. The Indians of New Mexico capture them in bas- 

 kets of wicker-work, nets, and by a running noose of horse hair at 

 the end of a stick. The noose opened wide is gently passed be- 

 neath the belly of the fish and gradually tightened ; a sudden jerk 

 captures the fish. By this method fish no longer than one's finger 

 are taken by Indian boys.
