XLITI. KYPHOSUS. 
Kyphosus Lacépéde, Hist. Nat. Poiss., 11, 114, 1802 (bigibbus = fuscus). 
Pimelepterus Lacépéde, Hist. Nat. Poiss., Iv, 429, 1803 (bosqui = sectatriz). 
Dorsuarius Lacépéde, Hist. Nat. Poiss., v, 482, 1803 (nigrescens = fuscus). 
Xyster Lacépéede, Hist. Nat. Poiss., v, 484, 1803 ( fuscus). 
? Opisthistius Gill, Proc. Acad. Nat. Sci. Phila. 1862, 245, (tahmel). 
Sectator Jordan & Fesler, subgen. noy. (ocyurus). 
Type: Kyphosus bigibbus Lacépede. 
Etymology: zvgé<, a hump, the word more correctly written cyphus, 
and referring to a deformed specimen with hump back. 
This genus contains some ten species, all but one confined to the 
Pacific Ocean, and most of them found in the East Indies. One of the 
species, Opisthistius tahmel, usually referred to this group, is probably 
the type of a distinct genus, distinguished by its elevated soft dorsal 
and anal.
