salmon : the scales are also imbricated, but rather larger, the rostrum exceeds the under jaw 

 more, and the teeth are neither so large nor so numerous as those of the salmon. Some of 

 them are almost entirely red on the belly and sides ; others are much more white than the 

 salmon ; and none of them are variegated with the dark spots which mark the body of the 

 other : their flesh, roes, and every other particular with regard to form, are those of the 

 salmon. 



i: Of the Salmon-trout we observe two species differing only in colour, They are seldom 

 more than two feet in length, and much narrower in proportion than the salmon or red char. 

 The jaws are nearly of the same length, and are furnished with a single series of small, subu- 

 late, straight teeth, not so long nor so large as those of the salmon. The mouth is wide, and 

 the tongue is also furnished with small subulate teeth, in a single series on each side : the fins 

 are placed much like those of the salmon. One of the kinds, of a silvery-white colour on the 

 belly and sides, and a bluish light brown on the back and head, is found below the Great 

 Falls, and associates with the red char in little rivulets and creeks. It is about two feet eight 

 inches long, and weighs ten pounds. The eye is moderately large, the pupil black, with a 

 small admixture of yellow, and the iris of a silvery-white, and a little turbid near its border 

 with a yellowish-brown. The fins are small in proportion to the size of the fish. Fins. — 

 D. 10—0; P. 13; V. 10 ; A. 12.— The other kind is of a dark colour on the back, and its 

 sides and belly are yellow, with transverse stripes of dark brown : sometimes a little red is 

 intermixed with these colours on the belly and sides towards the head. The eye, flesh, and 

 roe are like those of the salmon. Neither this fish nor the salmon are caught with the hook, 

 and we know not on what they feed. The white kind, found below the falls, is in excellent 

 order when the salmon are out of season and unfit for use." (Lewis and Clark, iii., 

 p. 66—68.)

This species is named in honour of a highly-valued friend, Captain James Clark 

 Ross, an officer who has had the singular fortune of being engaged in five succes- 

 sive expeditions of discovery in the Arctic seas : whose professional skill, exertions, 

 and perseverance, are the subjects of Sir Edward Parry's eulogium, and whose 

 scientific acquirements and contributions to Natural History are so generally known, 

 that any attempt of mine to commend him would be want of taste, were it not 

 allowable for one who has also spent the prime of his life in the same regions and
