it all the pieces common to the other genera, but 

 unequal. 



The pleuronectes furnish, along the sea-coasts in 

 almost all countries, an agreeable and wholesome nu- 

 triment. 



Individuals are sometimes found which have the 

 eyes placed on a different side from that in which they 

 are seated in the rest of their species. These indi- 

 viduals are named reversed (contournes) ; others, in 

 which the two sides of the body are equally coloured, 

 are named double. It is most frequently the brown 

 side which is thus repeated, but sometimes it is the 

 white also ! . 



We divide them as follows : 



Platessa, Cuv., 



Have to each jaw a range of trenchant obtuse teeth, 

 and most frequently to the pharyngeals, some teeth 

 en pave. Their dorsal advances just above the upper 

 eye, and leaves, as well as the anal, a naked interval 

 between it and the caudal. Their form is rhomboidal ; 

 the majority have the eyes on the right side. They 

 have two or three small cceca. Our seas possess some, 

 such as Pleur. platessa, L., Bl. 42. {the plaice, car- 

 re let, Fr. 2 ) 



1 The rose-colour cdflounder, Shaw, IV. ii. pi. xliii. is a flounder in 

 which the white side is double. 



2 N.B. The name of Carrelet, or petit carreau, has been applied 

 by some authors to the barbel, but contrary to the usage of our coasts 

 and markets- The true carrelet is a young plaice.
