Centrarchus, Cuv. 



Have the characters of the Pomotis, numerous spines in the anal fin, 

 and, further, a group of teeth, dense as the pile on velvet, on the tongue*. 

 From America. 



Priacanthus, Cut. 



Tlie Priacanthes have the body oblong, compressed, completely covered, 

 as well as the entire head, and even both jaws, with small rough scales; 

 tlie preoperculum dentated, and its salient angle spiniforra, whilst it is 

 itself dentated. Found in the seas of hot climates ■!•. 



DULES, CtiV. 



The Doules have the operculum, as in Centropristis, terminating in 

 spines; the preoperculum dentated, and the teeth dense as the pile on 

 velvet; but six rays to the branchial membrane ;|;. 



D. riipestris, Cuv., a species nearly resembling a carp, and 

 esteemed for its taste, is found in the fresh waters of the isles of 

 Bourbon and the Mauritius, where it is much esteemed §. 



Therapon, Ctw. 



The Tlierapons have a preoperculum dentated, an operculum termi- 

 nated by a stout spine; a strongly emarginate dorsal fin between the 

 spinous and soft part : the teeth of the external row pointed and stronger 

 than the rest. In some, the teeth of the vomer fall out at an early pe- 

 riod. They inhabit the waters of India, and are remarkable for a natatory 

 bladder, divided into two compartments by a stricture ||. 



It is hardly possible to separate the Datnia from them, although they 

 Avant the palatine teeth; their profile is more rectilinear; their dorsal fin 

 less emarginate^. 



Pelates, Ciw. 



Have the same internal and opercular characters as the Therapons; but 

 their teeth are uniformly dense as the pile on velvet, and the dorsal but 

 slightly emarginate **.
