WELSH CHARR. 71 



distinguished from that species by having only a few teeth 

 on the most anterior part of the vomer:* but the teeth, the 

 gape, and the eye are much larger in the Welsh Charr than 

 in that from the North. The outlines of the heads introduced 

 as a vignette show these distinctions : the great difference in 

 the size of the eye of the two species is an obvious character, 

 and the form and relative size of the operculum and suboper- 

 culum of the one compared with the same parts in the other 

 are additional distinguishing features. Dr. Richardson, in 

 the third part of the Fauna B or eali- Americana, devoted to 

 fishes, has figured the forms of the gill-covers and teeth of 

 several species of Salmo. Plate 92, fig. 5, A, B, represent 

 the head and teeth of a Welsh Charr from Llyn Cawellyn, 

 which is evidently of the same species as the fish here de- 

 scribed, derived from another locality. 



The Welsh Charr is the Torgoch or Red-belly of Wales, 

 and was formerly to be taken either in Llanberris Lake, or in 

 Llyn Cawellyn, two deep lakes situated on the east and west 

 sides of Snowden. The waters from a neighbouring copper- 

 mine are said to have destroyed or driven out the Charr from 

 Llanberris, where they were formerly very numerous ; and 

 it was remarked that some of these fish were caught in the 

 sea, at the mouths of rivers on this coast, after they disap- 

 peared from the lake. 



" Llyn Cawellyn," says Mr. Donovan, " is a vast lake of 

 unknown depth, sheltered on one side by an abrupt moun- 

 tain, which rises immediately out of the water, and in the 

 deep recesses at the base of which the Torgoch is supposed 

 to pass the milder seasons of the year in perfect security. 

 These fish approach the shallower parts of the lake in winter, 

 about the middle of December, appearing in small troops at 



* The teeth in the Parr extend along the whole length of the vomer.
