The lower lobe of the Caudal fin slightly longer 
than the upper. 
The fin rays are as follows: D. 15; P. 16; V. 
9; A. 10; C. 22. 
I have no doubt that this is the ** tuberculatus" of 
LeSueur. He describes his specimen as having but 
three tubercles. This was owing undoubtedly to 
the smallest tubercle having fallen off, which I find 
is the case with one on one side of the specimen 
before me, without leaving the slightest mark to 
point its location.

By the kindness of Mr. H. Erastus Clap, of 
Walpole, I received, in May, 1838, eight beautiful — 
fresh specimens of this species, which enabled me 
to test its goodness at my own table, besides supply- 
-ing several of my friends, who agreed with me, that, 
although its flesh was rather dry, it was much prefer- — . 
able to that of the “ Bostoniensis.” The largest 
of these specimens was twenty inches in length, 
and weighed three and a half pounds. From a spe- 
cimen fifteen inches in length, the following des- 
. eription is made, as being more nearly like the spe- 
. cimen from which Le Sueur drew up his descrip- 
tion, : than the larger specimens.
