AGANTHOPTERYGII. 129 



Eques, B1. 

 This genus cannot be removed from these Scienoides with two 

 dorsals. It is known by the compressed and elongated body raised 

 at the shoulders and ending in a point near the tail; teeth, small and 

 crowded; the first dorsal is elevated, the second, long and scaly; they 

 all belong to America.(l) 



The Scienoides, with a single dorsal, are subdivided ac- 

 cording to the number of their branchial rays. 



Those which have seven form various genera parallel to se- 

 veral genera of the Percoides ; their preoperculum is always 

 dentated. 



HiEMULON, Cuv. 

 A somewhat elongated profile, which has been thought to bear 

 some resemblance to that of a hog; the lower jaw compressed and 

 opening very wide; two pores and a little oval cavity under its sym- 

 physis; teeth, small and crowded. The parts of the lower jaw which 

 enter the mouth when it is closed, are generally of a vivid red, from 

 which circumstance their name is derived. (2) Their dorsal is 

 slightly emarginate, and its soft part scaly; they are all from Ame- 

 rica.(3) 



Pristipoma, Cuv. 

 The same preoperculum, and the same kind of pores under the sym- 

 physis as in Haemulon, but the muzzle is more gibbous, the mouth 

 not so deeply cleft, and the dorsal and anal are without scales. The 

 operculum terminates in an obtuse angle concealed in its membran-
