3. Gasterosteus Noveboracensis, Cuv. 



Dark brown above the lateral line ; beneath it, silvery. This species differs from the G. 

 trachurns in having- the dorsal plates narrower ; the lateral carina; 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 trachurns. See his paper " On the Species of Stickle- 

 back found in Ireland," Mag. of Zoology and Botany.

4. Gasterosteus quadracus, Mitchill. >4/~t/ZZ* 



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.
