margin straight; pectoral pointed 3.35 in body- ventral 1.25 in head; caudal peduncle small, com- 
pressed, its least depth 3.25; caudal spine short, stout, 2 in interorbital space, depressible, not in a 
groove, the space about somewhat concave: scales exceedingly small, ctenoid, those about pectoral 
region more or less smooth; lateral line nearly concurrent with dorsal profile below base of soft dorsal. 
Color in life (No. 03389), nearly black, with 6 bands of dirty white, first band beginning on 
lower jaw and continuing back to anterior edge of opercle and down as far as ventrals; a stripe of gen- 
eral body-color as wide as chin, beginning at chin and growing narrower until it ends on a line at 
anterior edge of gill-opening; second band including posterior portion of eye and just behind base of 
ventral; third band containing 2 small 3 ^ 8 llow bands; fourth, fifth, and sixth each with 1 yellow band, 
each of the 6 darker bands between the lighter bands also banded with yellow ones; the third and 
fourth with 4 bands, the fifth 3, and the sixth 2; dorsal nearly black, first 3 white bands continuing 
up on the dorsal; caudal same as dorsal, but slightly olivaceous toward base; other fins same as 
dorsal; snout and front of head with small whitish spots, the dark color forming a network around 
them; iris yellow; tail growing darker with age. 
Another example (No. 03416), dark brown in life; transverse bands of bright lemon-yellow bor- 
dered on each side by a narrow violet band, which is more distinct on forward part of body, the sixth 
anal ray yellow; dorsal and anal dark, nearly black; dorsal with narrow transverse bands of violet; 
pectoral with yellow toward base; ventrals dark. 
Color in alcohol, blackish brown, anterior half of head, throat and chest, and 6 narrow pale 
vertical bands on side, whitish, one behind eye silvery; first band running from just before first dorsal 
spine down side of head and chest including posterior margin of eye, to root of ventral, second begin- 
ning at last dorsal spine and first 2 dorsal rays, and running to spinous anal; the others run from 
the sixth and seventh, eleventh and twelfth, nineteenth and twentieth, and twenty-fifth and twenty- 
sixth dorsal rays, to the base of anal; last lateral vertical bar ill defined; dorsal and anal blackish 
brown, with about 12 vertical narrow gray lines on posterior half of dorsal, the second and third 
vertical bands extending a very short distance on basal part of dorsal parallel with spines and rays; 
anal with a few indistinct gray lines similar to those on posterior part of dorsal; caudal whitish; 
pectorals grayish; ventrals blackish. 
In adult examples the side has 4 or 5 blackish vertical lines running down each dark band; 
anterior part of head with dark brown reticulations, the anterior pale bars with dark brown vertical 
lines on reticulations; caudal dark brown; dorsal and anal blackish. Described chiefly from an 
example (No. 03416) taken at Honolulu. 
This species is fairly common at Honolulu, where specimens were obtained by Jenkins, by the 
Albatross, and by us. The 16 examples which we have examined range from 3.1 to 11.5 inches in 
length. This species, common at Samoa, is doubtless Bloch’s A. velifer.
