narrowly bordered in front below eye with white; adjoining interorbital band, continued on side of 
head and down on opercle, a broad white band; a broad blackish-brown band from opercle up to 
middle of spinous dorsal broadly edged with white; a blackish-brown blotch on back at base of first 
5 dorsal spines, bordered below with whitish; side with oblique golden olive bands following courses 
of scales; marginal portion of spinous and soft dorsal broadly blackish, not continued on posterior rays; 
a dusky streak running along basal portion of soft dorsal broadens out on posterior rays and forms a

We have examined 29 examples from Honolulu (9 collected by Jenkins), where the species is 
common in the markets, 4 from Kailua, 5 from Hilo, and 10 from Cocoanut Island at Hilo. The}' are 
from less than an inch to 7.2 inches long. Specimens were obtained by the Albatross at Honolulu 
and Waialua Bay, Oahu; Hilo and Puako Bay, Hawaii; common at Samoa.
