Posterior margin of the gill-cover very little curved: vomerine teeth confined to the anterior extremity: caudal even: back and sides spotted with purplish gray; ventrals plain white.

(Form). Closely resembling the Salmon, but of a more clumsy make: head and nape somewhat thicker: curvature of the posterior margin of the gill-cover much less considerable; margin of the preopercle more sinuous; subopercle larger with respect to the opercle, the basal margins of both nearly parallel to the axis of the body; a line drawn from the extremity of the upper jaw to the furthest point of the gill-cover passes beneath the eyes: vomer with only two or three teeth at its anterior extremity: tail, beyond the adipose, more bulky and muscular than in the Salmon: caudal even; in old fish rather convex: the other fins similar: number of fin rays,
D. 12 to 14; A. 11; C. 19, etc.; P. 14; V. 10.
Number of vertebrae fifty-nine. The female is characterized by having shorter jaws than the male, with the teeth less developed. (Colours). For the most part similar to those of the Salmon, but the back and sides, above the lateral line, more spotted; the spots being most abundant in the female. In the spawning season, the male acquires a red tinge: the female remains gray.
Migratory like the Salmon. A common species in the Tweed, where the young are called Whitlings. Found also in the rivers of Wales, Dorsetshire, and Cornwall. Apparently the same as the Sewen of Donovan, (S. Cambricus,) said by that author to be found in such great plenty on the coasts of Glamorganshire and Caermartbenshire; this last (which, according to Donovan, rarely exceeds twelve or fifteen inches in length, and from one to two pounds in weight) only a younger fish. It is also probable that the & Hucho of Fleming, and other British authors, is not distinct from the present species. Flesh inferior to that of the Salmon; cutting yellow.
