 sea near Nantucket, and beyond." Certain it is, I have never 

 seen it in Boston market ; and Mr. Newcomb, senior, the oldest 

 fishmonger in our market, who has repeatedly been at the 

 Banks of Newfoundland fishing, assures me, he never knew 

 the hank fish to be caught in our waters. Our fish is the spe-

 Richardson's guarded manner of speaking. I should judge he 

 had never seen a specimen of our species. The much larger 

 size of our fish, the length of the '^ callarias,^'' according to 

 Yarrell, being only '' from twelve to twenty-four inches," 

 which cannot be accounted for by mere difference of locality,
