Ser. altivelis, Cuv. ; Cuv. et Val., II, xxxv. Which has a 

 higher dorsal than the others; it is sprinkled with round and 

 black spots, on a ground of light brown; and 



Serr. phaeton, lb. pi. xxxiv, whose two middle caudal rays 

 unite in a filament as long as the body. 



We have separated from the Serrani, the 



Plectropoma, Cuv. 



Only differing from them in the more or less numerous teeth of the 

 lower edge of the preoperculum, which incline obliquely forwards, (l) 

 and the 



DiAcoPE, Cuv. 



Characterized by an emargination near the lower edge of the preo- 

 perculum, which receives a tuber of the interoperculum. The Indian 

 Ocean produces some large and splendid species.(2) 



Mesoprion, Cuv. 



The dental characters and fins of the Serrani with their dentated 

 preoperculum; the operculum terminating in an obtuse angle, not 

 spinous.(3) 



Numerous and beautiful species inhabit the two oceans. (4) Seve- 

 ral of them are very large, and their flesh is excellent.
