112 FISHES. 



symphysis as in Heemulon, but the muzzle is more gibbous, the mouth 

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

 culum terminates in an obtuse angle concealed in its membranous edge. 

 It is a very numerous genus, whose species are found throughout the hot 

 parts of both oceans*. 



DlAGRAMMA, CtlV. 



The cavity beneath the symphysis wanting, but the two small anterior 

 pores still remain ; besides which, there are two larger ones beneath each 

 branch. In every thing else, the jaws, opercula and fins are like those of 

 Pristipoma. They are found in both oceans : those of the Atlantic have 

 the largest scales j. 



Those of India are the most numerous and have smaller scales, a more 

 convex front and a very short muzzle J. 



The Scienoides with a single dorsal and less than seven branchial rays, 

 are still more subdivided : in some of them the lateral line extends to the 

 caudal; in others it is interrupted. Among the former we place the fol- 

 lowing genera : 



LOBOTES, CuV. 



A short muzzle; lower jaw prominent; body elevated; the posterior 

 angle of its dorsal and anal so elongated, that, with the rounded caudal, 

 it appears to terminate in three lobes. Four groups of extremely small 

 points are visible near the end of the jaw; they inhabit both oceans §. 



Cheilodactylus, Lacep. 



Have the body oblong ; mouth small ; numerous spiny rays in the dor- 

 sal ; inferior rays of the pectorals simple and continued beyond the mem- 

 brane, as in the Chirrhites ||.
