Class IV. GWYNIAD SALMON. 423 



the second is thin, transparent, and not distant 

 from the tail; the pectoral fins have eighteen 

 rays, the first the longest, the others gradually 

 shortening ; the ventral fins are composed of 

 twelve, and the anal of fifteen, all branched at 

 their ends ; the ventral fins in some are of a fine 

 sky blue, in others as if powdered with blue 

 specks ; the ends of the other lower fins are 

 tinged with the same color; the tail is very 

 much forked; the scales large, and adhere close 

 to the body.* 



* De la Cepede in the Supplement to his Histoire des Pois- 

 sons, v. 696, gives a slight description of two supposed species of 

 Salmon discovered by le citoyen Noel, and which he asserts are 

 unknown to British ichthyologists. 



One found in Loch Lomond, he has, from its resemblance to 

 an herring, for which it has been taken, denominated le Core- 

 gone clupeoide. Its head is small, convex above, devoid of 

 smaller scales, but distinguished by a few larger, or plates : 

 it grows to the length of sixteen inches. 



The other, le Salmone Cumberland, inhabits the lakes of 

 Cumberland and Scotland. The head is described as small, the 

 eyes large, and placed near the nose ; the mouth large and fur- 

 nished with two rows of teeth on the tongue 5 the scales small ; 

 the lateral line straight ; the adipose fin long ; the general color 

 white, the back grey ; the flesh pale and tasteless. Ed.
