130 MALACOP. ABDOM. SALMON FAMILY. 



in some parts of tlie south and south-west of Wales, 

 where it is named the Sewin, CS. camhricus of Do- 

 novan). Its flesh, which is of a pale yellowish co- 

 lour, is much inferior in flavour to that both of the 

 Salmon and Salmon-trout. 



(Sp. 126.) S.trutta. Salmon-trout, or Sea-trout. 

 This species rivals the Salmon in the elegance of its 

 form, and is almost as highly valued as an article 

 for the table. It is rather more robust in the gene- 

 ral form than a Salmon of the same size ; length of 

 the head, when compared with the length of the 

 body, as one to four; jaws nearly equal; teeth 

 strong, sharp, and curved backwards, those on the 

 vomer not confined to the anterior extremity but 

 extending a good way backwards, frequently eight 

 in number. The posterior free margin of the gill- 

 covers is less rounded than that of the Salmon, but 

 more so than that of the Grey Trout. The line of 

 union of the operculum wdth the suboperculum, 

 and the inferior margin of the suboperculum, are 

 oblique, forming a considerable angle with the axis 

 of the body of the fish. The posterior edge of the 

 preoperculum rounded. (Yarrell.) The first dorsal 

 is placed nearly half-way between the nose and 

 root of the caudal fin, the first ray short, the second 

 long, equal to the length of the base of the fin; 

 adipose fin rather large, situate mid- way between 

 the hinder ray of the first dorsal and the tip of the 

 tail ; tlie latter slightly forked, but in old individuals 

 becoming nearly square. Number of fin-rays :
