Color in life, head brownish yellow before eyes, the jaws lighter yellow; cheek washed with 
brownish and blue, throat greenish; nuchal and opercular regions brownish orangey body salmon-color 
above, the belly lighter yellow, most of the scales with an edging of greenish blue; a deep blue line 
from nostril before and behind upper part of eye; upper lip deep blue, the streak forming an interrupted 
line before eye; lower jaw with 2 blue cross lines, 1 marginal; a dark-blue spot behind angle of mouth; 
deep blue blotches on interopercle; dorsal deep blue with a peculiar jagged stripe of light brownish 
yellow; anal with blue spots at base, then light yellow, then deep blue, then green with blue edge;, 
caudal brownish yellow, with bright blue edgings and a median area of bright golden green; ventrals 
golden, trimmed with bright blue; pectoral golden with deep blue above and greenish blue on lower 
rays, a salmon streak across base with greenish blue behind it. 
Another example (No. 03040, 10 inches long) was in life pale coppery rosy, darker on first 3 rows 
of scales; the center of each scale in the first 5 rows greenish blue; under parts pale rosy, with 
orange wash; head pale rosy, a small postocular blue spot, a short blue line forward from eye, and a 
second of same color on upper lip and across cheek to eye, where it has a slight break, then continues 
under eye as a greenish-blue bar; under lip with narrow blue edge; chin faded salmon, with a double 
blue crescent; space from chin to isthmus bright blue; an oblong bright blue spot on, subopercle, 
behind which is a smaller irregular one bordered above by a broad greenish-blue space; dorsal green- 
ish blue, with a broad submedian orange band, the lower. greenish-blue band made up of large, scarcely 
connected, bluish spots, the upper half continuous with a narrow bright blue border; a small orange 
blotch on base of last dorsal ray; caudal pale rosy at base, then with a greenish bar, followed by a 
broad rosy bar, then by a broad terminal greenish-blue bar, dark blue in front, greenish in middle 
and pale blue on outer third; upper and lower edges of caudal blue, below which is a broad rosy 
orange stripe; anal greenish blue at base, then a broad orange stripe, the outer half greenish blue with 
narrow bright blue edge; pectoral orange anteriorly, pale bluish behind, the anterior border blue; 
ventrals orange, anterior edge and tip blue; iris pale orange. 
Color in spirits, light dirty grayish white, lighter below; a narrow pea-green stripe on edge of 
upper lip, breaking up into irregular spots from angle of mouth to lower edge of orbit, a similar stripe 
from nostril to eye and slightly'' beyond upper posterior border of eye, these lines sometimes continu- 
ous and unbroken; lower jaw edged with green, a broader pea-green cross-stripe at anterior edge of 
branchiostegal opening; subopercles each with a broad green stripe; line of union of gill-membranes 
broadly green; dorsal with a series of large olive-green spots at base and a broad band of similar color 
on distal half, these separated by a paler band and cut by intrusions from it both above and below; 
dorsal fin with a very narrow paler border; and with a series of greenish spots at base, then a broad 
pale yellowish white line, bounded clistally by an indefinite, wavy, black line shading off into the 
greenish of the distal half; last ray of anal dusky on its outer third; caudal greenish-olive at base and 
on produced outer rays, edges of fin above and below green; middle rays with a broad lunate area of 
pale green, scalloped proximal fV by dark green, separated from the lighter green base by a broad 
whitish interspace, the upper and lower edge also darker green; ventrals creamy white, the outer edge 
pale greenish; pectoral whitish, the upper edge dusky. 
There is some variation in the width of the green markings on the head, sometimes the stripes on 
the lower part of the head being very broad. 
This species is related to C. gilberli, from which it differs in the more strongly produced caudal 
lobes, in the narrower lines on the snout, the broader green lines on the throat, the absence of a green 
median line on the breast, and in the very different coloration of the fins. It is also near to Callyodon 
formosus, a species we have as yet failed to recognize. Besides the type obtained at Hilo, we have 4 
examples from Honolulu collected by us and 1 by Dr. Wood.
