144 SALMONIDES. 



bling very much the sea-trout, it is found, on care- 

 ful inspection, to be more slender, and to have a 

 greater number of red spots. The back is dusky ; 

 the ventral fin has a yellow tinge ; all the others 

 are of a palish purple. 



The tail is forked, and the fish measures some- 

 times four feet, though, ordinarily, it is only about

 New Hampshire, in the winter, frozen for the mar- 

 kets ; and from the northern parts of Maine, where 

 specimens have been taken,"" large as any produced 

 in the great rivers of Europe. 



We subjoin an extract from the Salmonia, 

 touching the hunchen or huco trout, with the be- 

 lief that it will lead to further investigation. 



"The hucho is /the most predatory fish of the 

 salmo genus, and is made like an ill-made trout, 

 but longer and thicker. He has larger teeth, more 

 spines in the pectoral fins, a thicker skin, a silvery 

 belly, and dark spots only on the back and sides. 

 I have never seen any on the fins. The ratio of 

 his length to his girth, is as 8 to 18, or, in well-fed 

 fish, as 9 to 20 ; and a fish, eighteen inches long, 

 by eight in girth, weighed 16,215 grains. Anoth- 

 er, two feet long, and eleven inches in girth, and 

 three inches thick, weighed four pounds two oun-
