424 PISCES (OSSEI) MALACOPT. [SALMO. 



shorter, and not so much forked ; in very old fish nearly even : the fleshy 

 portion of the tail rounded at its extremity : pectorals with their inferior 

 margin straight : number of fin- rays, 



D. 13 ; A. 11 ; C. 19, &c. ; P. 14 ; V. 10. 



Number of vertebrae fifty-eight. (Colours.) Darker in the body, and 

 lighter in the fins, than the Salmon : back and sides, above the lateral 

 line, more thickly spotted ; the spots assuming the form of the letter X ; 

 those above sometimes surrounded by a pale circle; gill-covers and cheeks 

 spotted, as well as the dorsal and adipose fins : ventrals always plain 

 white. 



A common species, inhabiting the sea and rivers. Enters these last 

 about the end of May or beginning of June. Is the Salmon-Trout of the 

 London markets. Flesh red, and highly esteemed. Food, according to 

 Sir W. Jardine, principally the Talitrus Locusta, or common Sand- 

 hopper. Obs. According to Agassiz, the 5. Lemanus of Cuvier is the 

 same as the present species. The Sea-Trout of Pennant appears to be 

 identical with the species last described, which is called by the above 

 name in some rivers.

This is held to be a distinct species by Sir W. Jardine, and some other 

 of our naturalists. I must confess, however, that I have been unable to 

 discern any appreciable difference between it and the last, of which, in the 

 opinion of Mr. Yarrell and myself, it is only the young of the first year. 

 Found in the Solway, the Tweed, the Esk, and a few other rivers in the 

 North. Is sometimes called a Whiting or Phinor. Pennant says it never 

 exceeds a foot in length. According to Sir W. Jardine, the fish in the 

 Solway average from a pound to a pound tind a half in weight, very seldom 

 reaching two pounds. It is added by this last gentleman, that "one of the 

 most marked appearances of this fish, is the great proportional breadth of 

 the back, and the peculiar grayish green colour of the upper parts." 



106. S. Fario, Linn. (Common Trout.) Gill-cover 

 produced behind into a rounded angle : vomerine teeth 

 extending the whole way : maxillaries reaching to a vertical 

 line from the posterior part of the orbit : caudal slightly 

 forked : back and sides with numerous red spots.

LENGTH. From one to two feet; sometimes more. 



DESCRIPT. (Form.) General proportions resembling those of the S. 

 Trutta : differs from that species in the form of the gill-cover, which is 

 much more produced behind, forming at its distal extremity a rounded 

 angle; basal margins of the opercle and subopercle rising more obliquely:
