 Scaridea octodon Fowler, Fishes of Oceania, p. 368, fig. 59, 1928 (type locality, 



"Hawaiian Islands"; I examined the holotype, an old specimen without a 



readable label in the jar, which Fowler deduced came from the Hawaiian 



Islands. Without doubt the deduced locality is wrong, since the specimen 



is in all respects this species, of which I have studied a large series from the 



Western Atlantic).

Like many other scarids, this species shows sexual dichromatism. 

 Longley (in Longley and Hildebrand, 1941, p. 209) says that when 

 alive, males have a dark-margined caudal fin, a narrow blue line with 

 a red one behind it extending from angle of mouth to eye, and a blue 

 (blackish in alcohol) pectoral base. I have observed that mature 

 males may have the isthmus region dark purplish brown. Females 

 have a light blue opercular margin. 



This species is characterized by the development of 1 to 4 canines 

 on each side of dental plate of upper jaw, the posterior canine being
