ACANTHOPTEHYGIANS. Ill 



One of them is found in America, — Pog. fascc, Lacep. II, xvi*, 

 of a silver colour, when young marked with vertical brown bands, 

 which becomes as large as the aS'c. umbra, and, like it, has branched 

 appendages to the natatory bladder -j-. This fish produces a sound 

 still more remarkable than any of the other Scienoides, which has 

 been compared to that of several drums. Its pharyngeal bones are 

 furnished with large teeth as if paved J. 



Eques, Bl. 



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 AmericaS. 



The Scienoides, with a single dorsal, are subdivided according to the 

 number of their branchial rays. 



Those which have seven rays form various genera parallel to several 

 genera of the Perches ; their preoperculum is always dentated. 



H^MULON, CllV. 



A somewhat elongated profile, which has been thought to bear some re- 

 semblance to that of a hog; the lower jaw compressed and opening very 

 wide ; two pores and a little oval cavity under its symphysis ; teeth small 

 and dense as the pile on velvet. The parts of the lower jaw which enter 

 the mouth when it is closed, are generally of a vivid red, from which cir- 

 cumstance their name is derived )|. Their dorsal is slightly emarginate, 

 and its soft part scaly; they are all from America^. 



Pristipoma, Cuv. 



Have the same preoperculum, and the same kind of pores under the 



* Lonchurus barbatus, Bl. 360. 



f It is the Labrus grunniens, Mitch. Ill, 3 ; the Sciana fusca and gigas, Id., appear 

 to be the same species at a more advanced age, and every thing proves it to be also 

 the Labrus chromis, L.; finally, the Pogcnathe courbhie, Lacep. V, 121, is the same. 

 Add, Ombrina Fournieri, Desmar., Diet. Class. d'Hist. Nat.; its cirri are almost im- 

 perceptible. 



X They are figured by Ant. de Jussieu, Mem. de 1'Ac. des Sc. 1723, pi. xi.

 Perca formosa, L., which is not the same as the preceding one, Catcsb., II, vi, 1; but 

 it is the Labre Plumierien, Lacep., Ill, ii, 2; and the Guaibi coara of Marcgr., p.
