340 NEW YORK STATE MUSE/UM 



1898 the state museum obtained a few specimens from Shinne- 

 cock bay, Peconic bay and several stations in Great South bay. 

 This species appears to run upstream farther than the others. 

 In the aquarium it often attacks fish and tears their fins into 

 shreds. During the breeding season the male becomes of a rosy 

 hue beneath. It is a hardy fish, enduring captivity better than 

 the other species. Often found in pools in the woods where 

 seemingly no other fish occur. (After Eugene Smith 1 ) 



Genus GASTEROSTEUS (Artedi) Linnaeus 



Sticklebacks with the innominate bones coalescent on the 

 inedian line of the belly, behind and between the ventral fins, 

 forming a triangular or lanceolate plate. Gill membranes 

 united to the isthmus; tail slender, and usually keeled; skin 

 variously covered with bony plates; dorsal spines three in num- 

 ber, strong, with nondivergent bases. Species numerous. 

 Fresh waters and shores of all northern regions; the species 

 highly variable, those found in the sea usually with the body 

 completely mailed, the fresh and*brackish water forms variously 

 mailed or even altogether naked.
