ARGUS FLOUNDER. 3\Q 



lateral line on the upper side is rough or spiny, 

 as in the Flounder, as also the bases of the dorsal 

 and anal fin, but the spines on those parts are all 

 strait, whereas in the former species they are inter- 

 mixed with curved ones ; in colour it resembles the 

 Flounder.

This elegant species is of the same general form 

 with the Turbot, and is of a pale yellow, or rather 

 a yellowish white colour on the upper side marked 

 by numerous eye-shaped spots, consisting of bright- 

 blue circles with yellow centres : the whole skin is 

 also marked both on the body and fins with small 

 blue and brown specks, and is covered with small 

 scales : the larger spots first mentioned vary some- 

 what in different individuals, as well as on different 

 parts of the same fish, being sometimes formed by 

 complete circles of blue, but more commonly by 

 two or three broken crescent-shaped marks of that 

 colour : the under side is of a whitish or pale grey 

 colour ; the lateral line is arched over the pectoral 

 fins, and is thence continued strait, to the tail.
