 canines veiy small. One dorsal, with ten spines, and with the basal 

 halt' scaly ; the anal fin with three spines. Opercnlar points in- 

 distinct ; the angle of the pra^opercnlum very slightly serrated. 

 Scales moderate, Avithout visible serratnrc. Cleft of the mouth 

 obliipie, the lower jaw longest; eye moderate. Pyloric appendages

This fish cannot be referred to Ccesio, ha\-ing distinct bands of 

 palatine and vomerine teeth ; nor to Cuvier's family of Mcenidce, 

 not having the mouth more protractile than the greater part of the 

 Percidce. It is very probable that Ccesio lunaris, and some other 

 similar species which I have had no opportunity of examining, should 

 also be referred to this genus.

Skeleton. — The skuU of this species is distuigmstod by the ex- 

 ceedingly high crest, which extends from the forantca oaipitule to

 ported by a bony ridge arising from the supiaoccipital bone and
