Gairdner, 



in lit. 



[From the labels having dropped off, I cannot refer the fragments of any of the specimens 

 to this species with certainty, but I am inclined to think that a spine, containing sixty-six ver- 

 tebrae, belongs to it, and if so, the gill-cover is extremely like that of S. Scouleri (pi. 93), and 

 the bones of the head have the same fibrous structure which we have noticed in the descrip- 

 tion of that species. None of the teeth have been preserved, but those of the lower jaw appear 

 to have been fixed in cartilaginous sockets, which have separated from the bone, leaving a 

 rough surface. The palate and upper jaw-bones are lost. The union of the branchial arches 

 at the root of the tongue is longer and narrower than in the preceding two species, and the 

 gill-openings consequently are more ample. Either this species or the S. Scouleri, or perhaps 

 both, are named " Red-char " by Lewis and Clarke. See p. 1 62. — R.]

Salmo Scouleri, p. 158. Plate 93. 



" The Ekewan, which averages thirty pounds in weight, ascends the Columbia 

 towards the end of August and in the month of September. Its flesh is paler and 

 of inferior quality to the four preceding kinds." [From Dr. Gairdner's descrip- 

 tion of this species I have little doubt of its being the same with the S. Scouleri of 

 Observatory Inlet (p. 158), and I should without hesitation have referred to it the 

 spinal column and opercular bones noticed at the close of the account of the 

 preceding species, had not Dr. Gairdner mentioned that no specimen of the Ekewan 

 was sent, as he had not obtained one small enough to be put in spirits. — R.] 



" Colour. — Body above mesial line smoke-grey, passing on head and tail into bluish-grey : 

 a slight reddish tinge at the root of the dorsal and between it and the adipose. Fins bluish- 

 grey, and all tinged with red except the caudal, which, with the back, is studded with irregular 

 semilunar and stellated blackish-brown spots. A large vermilion-red patch in the concavity
