PLEURONECTIDJE. 



numerous ; the upper eye nearly over the lower ; the lateral 

 line but very slightly curved over the pectoral fin, and 

 marked with numerous rough stellated tubercles at its com- 

 mencement, some more of which are arranged in two lines, 

 one above, the other below the lateral line throughout its 

 course : the body smooth ; the scales small ; the dorsal and 

 abdominal lines armed with a series of denticulated tubercles, 

 one in each space, between the rays, and alternating with 

 them ; the dorsal fin extends from the eye almost to the 

 tail ; the ventral fin is placed a little farther back than in the 

 Plaice, under the margin of the operculum ; the anal fin, 

 preceded by a spine directed forwards, also commences far- 

 ther back ; both dorsal and anal fins terminate on the same 

 plane ; the fleshy portion of the tail narrow, its rays elon- 

 gated, and almost square at the end. The fin-rays in num- 

 ber are

The colour of this species is variable, the shades of brown 

 depending on the nature of the ground from which the fish 

 was taken, but generally mottled with darker brown ; the 

 fins light brown, occasionally varied with patches of darker 

 brown, but generally lighter than the body. Examples 

 sometimes occur with a few indistinct reddish spots on the 

 upper surface ; but the roughness of the lateral line in the 

 Flounder, and its smoothness in the Plaice, is a distinguish- 

 ing character in these two species, however similar they may 

 happen to be in colour or size.
