250 PISCES. 



(The Flounder.) Nearly similar in form to the platessa, but 

 with lighter spots; more granules on the salient line of the 

 head; a small rough button on the base of each ray along the 

 whole of the dorsal and anal; lateral line covered with rough- 

 ened scales. This species ascends rivers to a great distance, 

 and individuals are frequently found turned. 



P. pola, Cuv.; Vraie Limandelle, Duham. Sect. IX, pi. vi, f. 

 3 and 4. The form oblong and approaching that of the Sole, 

 although wider, and distinguished from other Platessae with 

 trenchant teeth by a smaller head and mouth; body smooth and 

 lateral line straight. It is considered in France equal to the 

 Sole. 



P. limanda, L.; Bl., 46. (The Dab.) Form rhomboidal, like 

 that of the Flounder; eyes large, with a salient line between 

 them; the lateral line strongly curved above the pectoral; scales 

 rough, whence its French name Limande (from lima, file); the 

 teeth on a single range as in other Platessae, but narrower and 

 almost linear; the sides on which the eyes are placed of a light 

 brown, with some faded brown and whitish spots. (1) 



HiPPOGLOSSUS, Cuv. 



The shape and fins of a Platessa, with the jaws and pharynx armed 

 with teeth, which are most commonly strong and pointed; the form 

 is usually more oblong. 



PL hippoglossus, L.; Bl., 47. (The Holibut.) Eyes on the 

 right side; lateral line arcuated above the pectoral. From the 

 north seas, where it attains a length of six or seven feet, and 

 weighs from three to four hundred pounds. It is salted, dried 

 and sold by pieces throughout the North. (2) 

 The Mediterranean produces several smaller species, some of 

 which have the eyes on the left; one of them is the 



Pi. macrolepidotus, BL, 190; Citharus, Rondel., 314. Oblong; 

 lateral line straight; distinguished by the scales, which are 

 larger in proportion than in any other. 



Rhombus, Cuv. 

 Teeth small and crowded, or like those of a card in the jaws and

(2) The PI. limandides, Bl., 186, or Citharus asper. Rondel, 315, and \.\\e pin- 

 guis, Faber, Isis, torn. XXI, p. 870, also appear to be northern Hippoglbssi. Add
