and Labrador, with Descriptions of New Species. 263 
I found it in abundance along the whole southern coast of 
Labrador from St. Mary’s Islands, at the extreme south-west, 
to the mouth of the Straits of Belle Isle. Though so much 
larger, its habits are the same as those of the mucronatus ; 
lying oftentimes among the sea-weed at the surface in several 
feet water, and again concealing itself at the bottom under 
rocks.

Observed hitherto to range from New York to Maine. At 
Bras d'Or it is frequently taken while seining herring, and is 
! In comparing my specimens of Gunnellus from Labrador with those of Massa- 
chusetts, Mr. Girard has noticed | pied hers. one individual which indicates 
the existence on our coast of a spec rom both G. mucronatus and G. 
ingens. He has favored me with the Svid Aoii — 
GUNNELLUS MACROCEPHALUS Girard. 
“The size is nearly that of G. ingens from Labrador, and consequently much 
greater than that of G. mucronatus. It differs from G. ingens in having a propor- 
tionally mend head, soman a larger mouth and larger teeth. These last are longer 
than those of G. ingens: their r tip is club-shaped in both. They are arranged in 
two rows in front of. the j jaws ; the principal row t the inside one on the lower 
jaw, and the outside one on the upper jaw. The head forms one eighth of — em 
length; its profile is very convex eats the mtg afia in G. ingens 
Vexity of the d is in advance of the m4 mar ut to it a more d oe ap-

the height is dui greater. The lateral di m runs straight along the middle of the 
body. 'The vent, placed under ee thirty-fifth dorsal ray, is at an eq

to the third or half of the length of the priscijel ray itself, in imitation, on a small 
scale, of the finlets of Scomber and Polypterus, with this difference, however, that in

Chelan Beach. It is preserved in Prof, Agassiz’s cabinet.” i
