species but a few inches long, whose large thin scales are easily dis- 

 lodged. The same sea produces another, the 



R. candidissimus, Risso, Ed. II, f. 34; PL diaphanus, Schn. IV, 

 part ii, 309. Still smaller, wholly diaphanous, with a series of se- 

 parated red spots on the dorsal and anal. 

 In others the eyes are far apart, and the upper one is thrown backwards, 

 the interval between them being concave. At the base of the maxillary, 

 on the side on which the eyes are placed, is a small salient hook, and 

 sometimes a second one is found over the lower eye. Species of this 

 description are taken in the Mediterranean*. 



Solea,' Cuv. 



The Soles have, as their peculiar characteristic, the mouth twisted to 

 the side opposite to the eyes, and on that side only furnished with very 

 minute and crowded teeth, the opposite one being edentated. The form 

 is oblong; snout rounded, and generally projecting beyond the mouth; 

 the dorsal commencing at the mouth, and extending, as well as the anal, 

 to the caudal; lateral line straight; side of the head opposite to the eyes 

 usually covered with a sort of villosity. The intestine is long and has 

 several flexures, but no caeca. 



PL solea, L. ; Bl. 45. (The Sole). A well-known and common 

 species; brown on the side in which the eyes are placed; pectorals 

 spotted with black, &c. — one of the best fishes. 

 There are several other species, particularly in the Mediterranean \. 

 In some foreign species there is no distinction between the three ver- 

 tical fins J. 



MONOCHIRUS, CuV. 



One extremely small pectoral on the side with the eye, the opposite one 

 almost imperceptible or totally wanting. 



Pleur. microchims, Laroche, Ann. Mus. XIII, 356; Linguatula, 

 Rondel. 324. A Mediterranean species §.

 cus, Brousson. Dec. Ichth. pi. iii, iv; — PL argus, Bl., and lunalus, Gm., Bl. 48, or 

 better, Catesb., Carol. XXVII. 



f The Pols of Belon, 143, and of Rondel. 323, different from the one sold at Paris, 

 which is a Plaice, according to these authors, has the eyes on the left; I am not sure 

 it is the Rh. polus, Riss. Ed. II, f. 32, in which the eyes are on the right;— the PL 

 oeellatus, Seh. 40, the same as the PL RondeUtii, Sh., Solea ocula/a, or Pegouze, 

 Rondel., 322;— PI. la scar is, Risso, Ed. I, pi. vii, f. 32, and other foreign species to 

 he described in our Hist, des Poissons.

 sonien, Lac. Ill, xii, 2. or Jerri potoo, A, Russel, 70; but the description, Lacep. IV, 

 656, belongs to another species of the subgenus Rhombns; — the Horned-sole, Russ. 

 72, an incorrect figure ;—Pl. je.rreus, Cuv., or Jerre potoo, B, Russel, 71; — PI. pan, 

 Buck X i V, 42. 



§ It is probably the Pletir. mangilii, Risso, 310, Other species exist, some of 

 which are unquestionably confounded with the Achiri of authors. The /'/. trichodac- 

 tylus must also belong to this subgenus. Add, the pegouze of Risso, 308, Ed. II, f. 

 33; — Mon. theophile, Id.
