the gills. The first dorsal is a little behind the ven- 

 trals, which are large ; scales on the body, cheeks 

 and opercula ; the viscera resemble those of trouts. 

 These fishes belong to the sea, and are extremely 

 voracious. 



One species is found in the Mediterranean, S. 

 sauras, L., Sal v. 242 1 . 



The lake of Mexico has a species almost trans- 

 parent, S. Mexicanus, Cuv. : another equally trans- 

 parent, the teeth long, flexible, and partly terminated 

 like barbels, the muzzle exceedingly short, and the 

 fins remarkably brittle, (S. ophiodon, Cuv. ; Vana 

 motta, Russel 171.) is used in the Indies, dried and 

 salted, as a condiment 2 . 



1 Add S. sanrus, Bl. 384, which appears to me to differ from that 

 of the Mediterranean. Salmo fcetens, Bl. 384. 2. S. tumbil. Bl. 

 400. L'Osmere galonne, Lacep. V. vi. 1. Salmone varie, Id. V. 

 iii. 3. Osmere a bandes, Risso., first ed. p. 326. S. Bad't, Cuv., 

 Badi motta, Russel, 172. Salmo myops, Forster., BL, Schn. p. 421. 

 S. minutus, Lesueur, Ac. Nat. Sc. Philad. V. part I. pi. v. S. coni- 

 rostris, Spix, xliii. S. intermedins, Id. xliv. S. truncatus, Id. xlv. ; 

 and many new species which we shall describe in our Ichthyology. 



N.B. The E sox sy nodus, Gron., Zooph. vii. 1. Synodus, Schn. 

 Synode fasce, Lacep., appears to me to he only a saurus that had 

 lost its adipose dorsal, the smallness of this fin might easily cause it 

 to disappear, on rubbing, or desiccation. 



2 The Salmo microps, Lesueur, Sc. Nat. Philad. V. part I. pi. iii. 

 is, if not the same species, one very much approximating to it. M. 

 Lesueur makes of it his genus Harpodon, because he believed it had 

 teeth in the vomer ; but he mistook the pharyngeal teeth for the 

 vomerian, in consequence of the extreme shortness of the muzzle.
