230 MALACOP. SUB-BRACH. FLAT FISH. 



at Stoford, in Bridgewater Bay, in the month of 

 December. The name expresses its most charac- 

 teristic attribute ; the length being much greater in 

 proportion to the breadth than in any other British 

 Platessa. The fins are soft, the rays not projecting, 

 and the dorsal and anal extend to the very root of 

 the tail ; the latter elongated with the sides paral-

 and regular teeth* From the further description 

 given hereafter, this will be found to constitute a 

 very distinct and well marked species.

 and much narrower in proportion to the length than 

 in Platessa, the fins similar to those of that genus ; 

 jaws and pharynx with sharp and strong teeth ; 

 eyes and colour on the right side, at least in our na-
