CLASS PISCES. 381 



ciscus. It is parallel above, with the ventrals. They 

 live in the fresh waters of North America '. 



Leuciscus, Klein. 

 The dorsal and anal are short, and without spines and 

 barbels ; there is nothing particular in the lips. This 

 subdivision is numerous in species, but their flesh is 

 in little estimation. The names of Meunier, Chevanne, 

 Gordon, &c. are indiscriminately applied to them in 

 our various provinces 2 . 



We distinguish them according to the position of 

 their dorsal, a character which is not always suffi- 

 ciently defined. In some it corresponds above with 

 the ventrals below, or is parallel with them. 



Of this group we possess, 



Cyprinus dobnla, L. Bl. 5. (le meunier.) Head 

 broad ; muzzle round ; pectorals and ventrals red. 



C. idns, Bl. 6., and better, Meidinger 36. (le Gar- 

 don.) Of nearly the same colours, with the head less 

 broad, the back more elevated, and the muzzle more 

 convex. 



Cyprinus rutilus, L. Bl. 2. (the roach.) Body com- 

 pressed and silvery ; all the fins red. 



1 M. Lesueur has described seventeen species in the Journal of the 

 Academy of the Natural Sciences, Philadelphia, torn. i. 1817, p. 88. 

 &c, and figured nine ; but the first must be struck out, Cat. cypri- 

 nus, which is rather a labeo. Add Cypr. teres, Mitchill, Trans. New 

 York, I. vi. ii., and the Cypr'in sucel, Lacep. V. xv. 2. 



2 N.B. Bloch and his successors have not followed the usage of 

 the environs of Paris in the application of these French names, which 

 they have bestowed almost at hazard.
