Still another specimen (field No. 03473) was dusky olive; a scarlet stripe behind upper angle of 
gill-opening as long as head and very bright, its wide border black, not blending with ground color; 
a white crescent on caudal; posterior half of pectoral obscurely whitish. 
Color in alcohol, blackish brown; a horizontal band of buff equal to length of snout from behind 
upper margin of opercle bordered with deeper brown; median caudal rays broadly margined with dull 
buff, edge with narrow blackish marginal line; pectoral with blackish basal portion, outer portion 
grayish. 
Described chiefly from an example (No. 03512) taken at Honolulu. 
The species appears to be fairly abundant at Honolulu. Doctor Jenkins obtained II examples, 
Jordan and Snyder I, and we preserved 9. The Albatross obtained it at Honolulu and at Puako Bay, 
Hawaii. The 21 specimens examined are 6 to 10.6 inches long.
