3. Gasterosteus Noveboracensis, Cuv. 
Dark brown above the lateral line ; beneath it, silvery. This species differs from the G. 
trachurus in having the dorsal plates narrower; the lateral carinz of the tail more prominent, 
and the lateral line nearer the back. 
Mr. Thompson, Vice-President of the Belfast Natural History Society, Ireland, does not 
consider this species distinct from the trachurus. See his paper ‘‘ On the Species of Stickle- 
back found in Ireland,’’ Mag. of Zodlogy and Botany.

4. Gasterosteus quadracus, Mrircutu. 
Greenish brown above the lateral line; beneath this line, which is scarcely perceptible, 
darker and irregularly broken by the extension of the whiteness of the abdomen. In young 
specimens, the color is distributed in four or five bars, which become indistinct in the 
mature fish. To the under portion of the ventral spine is attached a reddish membrane, 
which makes this part to appear as if covered with blood, when the fish is suddenly darting 
through the water with this spine projecting. Three or four spines in front of the dorsal fin. 
The three foremost fixed, the posterior movable.

Entirely black. Ventral spines very long. Thirty-three lateral plates. Tail armed. Its 
form is more elongated, and its spines more slender, than those of the G. trachurus.
