now hardly exists west of the Kennebec and Penobscot, 
and even there is becoming yearly more scarce. In the 
British Provinces, and in California and Oregon, it still 
abounds. 
Sza Trout, Salmo Trutta.—According to Mr. Yar- 
rel, this fish is distinguished from the common salmon by 
the gill-cover, which differs in the following points :—The 
line of union of the operculum with the sub-operculum and 
the inferior margin of the sub-operculum, is oblique, forming 
a considerable angle with the axis of the body of the first.

the upper. It weighs from half a pound to four or five, or 
even, in rare cases, up to eight pounds; and its ordinary 
length is from 10 to 18 or 20 inches. In shape it is not

jaws are thickly supplied with teeth inclining inwards, and 
very sharp. In color it is dark brown, mottled with yel-

white below. It is marked on the sides with several dis- 
tinct round spots of a bright red color, each surrounded
