(lark vertical baud extending on the first 7 spines ; soft dorsal dark, with 

 sharply defined pale edge ; part of anal covered by scales dusky, with a 

 narrow darker margin; unsealed portion yellowish white; caudal and pec-

Chcetodon, Bleeker, Arcli. Nederl. Sci. Nat., xii, 5, 1876 (transferred to species of Poma- 

 canthus, as the first species of Chcetodon mentioned by Artedi belongs to the latter 

 group, and the first species mentioned by Lac6pdde under Pomacanthus belongs to 

 Zanclus). 

 Body much compressed and elevated, covered with small scales, among 

 which smaller ones are distributed so that the scries are not distinct; pre- 

 operde with a very strong spine at its angle, the vertical limb entire in 

 the adult, usually serrulate in the young; iuteropercle entire or nearly so; 

 dorsal fin entirely scaly, with 8 to 11 graduated spines; soft dorsal usually 

 much elevated in front; anal with 3 graduated spines; branchiostegals 6; 

 air bladder with 2 posterior horns; pyloric ca;ca numerous. Species few, 

 in the tropical seas; chiefly American; the young brilliantly colored, the 

 adult usually dull colored. The species vary greatly with age, and have 

 been almost inextricably confused, as the age variations are much more 

 striking than the specific distinctions. The number of dorsal spines is 

 usually diagnostic. (TTcuyWa, operculum; axa/'Oa, spine.)
