selves to be drag-gcd by the teetli for forty or fifty yards ;

This Great Trout is almost entirely confined to the lochs, 

 seldom venturing far either up or down any of the streams 

 communicating with them, and never descending to the sea. 

 It is known to spawn in September. 



The most usual mode of fishing for this Great Lake 

 Trout is from a boat, which is rowed gently through the 

 water ; the bait, as before mentioned, a small Trout, guarded 

 by six or eight large hooks ; the rod and line of great strength ; 

 for this fish is considered to be even stronger than a Salmon 

 of the same size, but not so active. Young fish from one to 

 two pounds' weight rise freely to the usual Trout flies. 



For the opportunity of obtaining a drawing of this fish 

 I am indebted to the kindness of Mr. Selby and Dr. 

 Richardson. 



The length of the head is to the whole length of head, 

 body, and tail, as one to four and a half; the depth of the 

 body not equal to the length of the head : the teeth large, 

 strong, and numerous, occupying five lines above and four 

 below, thus extending along the length of the vomer : the 

 free edge of the gill-cover rounded in the female, more angu- 

 lar below in the males ; the inferior edge of the suboperculum 

 and the line of its junction with the operculum oblique. The 

 commencement of the dorsal fin is half-way between the 

 point of the nose and the origin of the first upper caudal 

 ray ; the third dorsal fin-ray, which is the longest, equal to 

 the length of the base of the dorsal fin ; the soft fleshy fin 

 half-way between the last dorsal fin-ray and the end of the 

 caudal rays, and in a line over the origin of the last ray of 

 the anal fin : the ventral fins each with an elongated axillary 

 scale ; the fins rather small in size, but very muscular.
