100 FAMILY OF CYPRINOFDRS. 



^ adipose fin on .{ 

 J52 L the back.* ^ Body unprovided with true scales, - } SILUROIPES. 



* We give the name of adipose Jin to any fin that is not sustained by fin- 

 rays, and only consists of a fold of skin filled with fat. 



3. The CYPRINOIDES, ( Cyprinidee,) have a slightly cleft 

 mouth, weak jaws, most frequently without teeth, and a scaly 

 body, without an adipose dorsal fin. They are the least carnivo- 

 rous of the fishes. 



4. One of the principal tribes of this family is the CYPRINIJS, 

 which is composed of fresh-water fishes, and includes the Com- 

 mon Carp, the Gold-Jisli, the Ilarbi'l, the Gudyeon, the TVwcA, 

 &c. This group is characterised by the absence of teeth in the 

 jaws, by the existence of a single dorsal fin, and ordinarily the 

 scales are large. Most of these fishes feed on grains, herbs, &c. 

 They have in the back part of the mouth a masticatory apparatus 

 for crushing their food. 



5. The Carps, Cyprinvs, are distinguished by their long 

 dorsal fin which, as well as the anal, is provided with a more or 

 less strong spine for the second fin-ray. 



6. The Common Carp, Cypriuus carpio, is found in all 

 Europe, but has not yet been met with in the United States. It 

 delights in tranquil waters, and is easily reared in rivers and ponds; 

 the duration of its life is very long, and it is exceedingly prolific.
