I have seen but three specimens of this fish, and 
therefore conclude it cannot be as common as the 
two following species of “Stickleback.” One of 
these specimens was brought me from Provincetown, 
by Dr. Gould; another, was taken from the stom- 
ach of a codfish, in our market, by Mr. E. Freeman ; 
and the third was found at Boston, by Master Henry 
Parker. 
The specimen before me is two and a half inches 
in length; all its upper portion, to the lateral line 
on each side, is of a very dark brown color, almost 
black; beneath, silvery. Sides, armed with strong, 
vertical bony plates, upwards of thirty in number, 
diminishing in size towards the tail; those at pos- 
terior portion of the body, with a lateral crest, termi- 
nating at the base of the caudal fin. Head, half an 
inch in length. Diameter of eye, half a line. Lower 
jaw slightly projecting beyond upper.  Gill-covers 
silvery. Outer edge of Ventral spine, serrated 
throughout its whole extent ; serrations of the inner 
edge scarcely discernible. 'The second Dorsal spine 
much larger than either of the others. The pos- 
terior Dorsal spine very small. 
The fin rays are as follows: D. 3-11; P. 10; V- 
1-1; A. 1-8; C. 12. 
At first sight, this resembles the “G. trachurus.”
