122 REPOET OF COMMISSIONER OF FISH AND FISHERIES. 



The colors of this char, as giveu by Eichardsoii, are obscure, as they 

 were based on the appearance of a dried skin. There appear to have 

 been yellow or orange spots along the sides. Lower parts white or yel- 

 low. We have been able to obtain no specimens for examination.

 Variety of S. aVipes, (Rich.) 

 The Iviksarok of the Greenlaiiders. 



Sp. Ch. — [Condensed from Sir John Richardson's description.] Knob ' 

 at point of lower jaw, received in notch between intermaxillaries. Back 

 nearly straight. Teeth much as in S. alipesy as are also many other 

 anatomical characters, for which see sp. ch. of S. alipes and " diagnosis " 

 below. Lower jaw, when depressed, slightly longer than from snout to 

 nape. Scales tiled, small, roundish. 



Colors, (according to Captain Eoss :) Body above the lateral line^ 

 deep green, softening towards the belly, which is of a beautiful yellow- 

 ish-red tint posterior to the pectoral pin. Under parts white, slightly 

 clouded by yellowish-red. On the sides several rows of red spots, prin- 

 cipally distributed between the lateral line and the yellowish red of the 

 belly, varying in size, the largest being as big as a pea. Dorsal fin like 

 the back. Under fins dusky-red, the anal paler, and the first rays of 

 the pectorals, ventrals, and auals white.

Hab. — Small hikes in Boothia Felix. (Eichardson.) 



Diagnosis. — In many characters this fish agrees with the S. parJcei, , 

 (nobis J found in the head-waters of the Columbia, west of the Eocky ' 

 Mountains. The latter has more brauchiostegals, and also light-green i 

 spots on the back, not noticed in the description of 8. nitidus. From 

 S. alipes, Eichardson gives the following distinctive characters : Body 

 thicker than that of S. alipes ; belly more prominent, fins shorter, anus 

 farther back ; head less arched above and in profile ; mesial ridge and I 

 lateral porous curves less prominent ; no radiating lines above the orbit, , 

 which is proportionately nearer the snout; upper jaw shorter. 



This fish, the S. alipes, 8. bairdli, and S. parlcei, agree in possessing \ 

 characters almost sufficient to inclnde them in a distinct subgenus. They 

 all belong to the chars, (subgenus Salvelinus of Nilsson,) bnt in addi- 

 tion have an elongated, fleshy projection standing np from the i)oint of the 

 lower jaw, which is received into a toothless notch between the premax- 

 illaries. They, in addition, have a mark common also to the S. fontinalis, 

 Mitchill; this is in having the first rays of the pectorals, ventrals and 

 anals yellow, red, or white. Koue of the black-spotted fronts, or sal- 

 mon, have these rays in color specially distinguished from those of the 

 rest of the fin.
