Sticklebacks are not uncommon in the State of New 

 York, some being found on the island upon which the city 

 of Xew York is built ; indeed, there is one species sup- 

 posed to be peculiar to this State, and has therefore been 

 called the Xew York Stickleback (G. JYeoboracensis). The 

 other species found in the same State are G. biacukatus, 

 or two-spined, G. quadracus (PI. IV., Fig. 1) ,or fivc-spiued, 

 and G. occidcntalis, or many-spincd stickleback.

 small fish, and is said to do well in confinement. It be-

 followed the moustache movement, having barbules around 

 the mouth. Fish having these appendages are said to feed 

 at the bottom of rivers and lakes. Loach, like most of 

 the fish that we make use of for the Aquarium, live 

 on larvae and small worms, which can be supplied to them 

 during the summer, but in winter they must be satisfied 

 with such food as they can get. The Loach is not, how- 

 ever, found in the State of New York, but is here repre- 

 sented by the Cat-fish, which also has the barbules attached 

 to its mouth. There are several species, but the best for 

 the Aquarium, on account of its size, is the black Cat- 

 fish (Pimclodus atrarius) which is found in AVappiuger's 

 Creek, a tributary of the Hudson, in Dutchess county, and 

 is about four and a half inches in length. 



The Carp (Cyprinis carpio) is a native of Southern 

 Europe, and it is said to be suited to the Aquarium, as 

 it frequents ponds and still water. A fish which lives in
