on middle of side; thin, finely ctenoid; scales on vertical fins, head, and helly, small, very small on outer 
portions of vertical fins; series of scales on side disposed in very oblique series; lateral line very 
strongly arched, not continued behind base of last dorsal rays. 
Color in life (field No. 03435), general color in front and below, including paired fins, light violet, 
lighter on snout and below; dorsal, excepting first 2 spines and membranes, which are violet, caudal, 
anal, and upper posterior part of side, chrome yellow; lips pinkish; a broad black ocular bar becoming 
narrower above, narrowly edged on each side with white, extending from interopercle almost to origin 
of dorsal; about 6 narrow yellow lines across interorbital area; a series of 8 narrow dark bars running 
forward and downward from base of dorsal, the first 5 extending down to humeral region, the last 3 
meeting at right angles, the last 3 bars of a similar series of 12 bars on lower part of body, the first 9 
bars of which meet the fifth bar of upper series about at light angles; soft dorsal edged with black, an 
oval black spot on its center; lower edge of anal with a narrow black stripe outside of which the edge 
is light yellow; caudal broadly tipped with light violet, two narrow brownish bars across its center. 
Color in alcohol, very pale or whitish, greater portion of side pale olive gray; about 8 dark-gray 
lines running obliquely up from head to dorsal, and others posteriorly above lateral line; side with 
about 1 1 oblique dark-gray lines running to anal; a broad dark-brown band beginning on nape before 
dorsal and running down to eye, continued below wider and blackish, with narrow whitish border in 
front; margin of dorsal to angle on soft tin, narrowly blackish; longest dorsal rays with black spot 
on distal portion; margin of soft anal with narrow black line running parallel with lower margin; 
margin of caudal grayish with a narrow dark-gray submarginal line; pectoral and ventrals grayish. 
Described from an example (No. 04562) 6.25 inches long, from Honolulu. 
We have 28 specimens, 4 to 8.2 inches long, from Honolulu, where the fish is common. Others 
were secured at that place by the Albatross. The species occurs also at Johnston Island and Samoa.
