450 PLEURONECTIDiE. 



m-0. Adult : stuffed. Frith of Forth. 



p. Adult : skin. From Gronow's CoUection. — Type of the species. 



Pleuronectes cynoglossus, Fabr. Faun. Groenl. p. 163, or Pl.pinguis, 

 Fabr. Vidensk. Selsk. Naturv. & Math. Afliandl. i. p. 43. tab. 2. fig. 1, 

 is probably identical with PI. cynoglossus, Gronov. & Linn., as the only 

 difference of any importance appears to be that the Greenland fish is 

 said to have 72-74 rays in the anal fin. It is evident, however, from 

 a single glance at the figure, that it is genericaUy different from 

 Hippoglossv^. 



15. Pleuronectes elongatus. 



Platessa elongata, Yarrell, Sitppl. Brit. Fishes, and Brit. Fishes, 2nd 

 edit. ii. p. 318, and 3rd edit. i. p. 619.

The height of the body is two-sevenths of the total length (without 

 caudal), the length of the head nearly one-sixth. Scales of medium 

 size, with numerous radiating striae on the free portion. The lateral , 

 line makes a slight curve above the pectoral. Jaws subequal an- 

 teriorly, maxillary shorter than the eye ; interorbital ridge prominent ; 

 the upper eye is somewhat in advance of the lower. The longest 

 rays of the dorsal fin are on its middle, and its distance from the 

 caudal is much less than the depth of the free portion of the tail. 

 The pectoral is about half as long as the head, and twice as long as 

 the ventral. Brownish. (Yarr.) 



Bridgewater Bay. — The single (typical) specimen was 7f inches 

 long ; it was not in Mr. Yarrell 's Collection when purchased by the 

 British Museum.
