of longest rays about equal to that of longest spines; membrane deeply notched between anterior 
spines, the notches growing shallow posteriorly as the scales approach edge of fin; second anal spine 
longest, about equal to highest dorsal spine; membrane deeply notched between first and third spines, 
the latter closely connected with rayed portion of fin; border of anal fin extending a little farther 
posteriorly than that of dorsal; caudal truncate, upper rays slightly longer than lower, 0.78 of head; 
pectoral 0.85 of head; ventrals not quite reaching vent. 
Color in alcohol, dull silvery, brownish along the back, the dark color extending downward in 
region of pectoral fin; scales on greater part of body with darker centers and lighter edges; posterior 
part of body with many dark spots about half as large as pupil; head with a vertical brownish-black 
band, the posterior border of which passes from insertion of dorsal through posterior border of eye, 
thence curving backward to origin of ventrals; width of band somewhat less than diameter of eye; 
interorbital area, snout, and upper lip dark brown; dorsal and anal narrowly bordered with dusky, 
rays tipped with white; scaled portion of dorsal with large irregular dusky spots separated by narrow 
light spaces, which take the form of a network; caudal light, broadly bordered with dusky; pectoral 
plain; ventrals blackish toward the free margins. 
Described from the type, No. 50880, U. S. Nat. Mus., 59 mm. long, from station 4032. 
Other specimens, among which are cotypes, No. 7732, L. S. Jr. Univ. Mus., differ little from the 
type. Specimens were taken off the southern coast of Oahu at station 4032, depth 27 to 29 fathoms; 
station 4031, depth 27 to 28 fathoms; station 4034, depth 28 fathoms.

Head, measured to end of opercle, 0.29 of length (to base of caudal fin); depth 0.46; depth of 
caudal peduncle 0.12; eye 0.34 of length of head; snout 0.4; interorbital space 0.32; D. xiv, 15; A. 
17; scales in lateral series 28; in a slanting series from origin of anal toward origin of dorsal 21. s 
Suborbital with 3 prominent spines which curve downward and backward; lower or anterior one very 
small, in some specimens preceded by a fourth minute spine; the upper or posterior two about equal 
in length to diameter of pupil; preopercle with a strong, slightly curved spine at its angle, which 
extends to a vertical through posterior border of opercle, excluding the flap; length of spine 0.34 of 
head; margin of preopercle above spine with sharp denticulations; below spine with 2 small spines, 
the upper of which is the larger; opercular spines not grooved; interopercle with denticulations; teeth 
fine, brushlike, trilobed, the lateral lobes much shorter than the median, all being sharply pointed; 
pseudobranch ife large; gillrakers 5 + 15, slender, pointed. 
Scales large, regular, strongly ctenoid; those on snout, chin, and interorbital space minute; dorsal, 
anal, and caudal densely scaled; lateral line arched over the pectoral, extending along back near base 
of dorsal, disappearing near end of soft dorsal fin. Dorsal spines growing gradually longer from the 
second to the last; the first half as long as the second; the last equal in length to distance between tip 
of snout and posterior border of eye; membranes of first 5 spines notched, membrane between 
first and second spines nearly cleft to base, the notches growing successively more shallow between the 
following spines; membranes between first and third spines without scales, the scaled area beginning 
behind third spine; fin rounded posteriorly, its edge reaching a vertical through base of caudal; third 
anal spine longest; membranes between spines deeply cleft, without scales except on a narrow area 
along the base; third spine closely attached to rayed portion of fin; posterior edge of fin pointed, 
extending nearly to a vertical through middle of caudal; edge of caudal truncate or slightly convex; 
tips of rays without scales. Ventral sharply pointed, the first ray being filamentous at tip, extending 
to origin of anal; pectoral when depressed extending to a vertical through vent. 
Color in alcohol, light brown with a yellowish tinge; lips, interorbital area, chin and throat 
somewhat dusky; membranes covering suborbital and opercular spines dark; scales of body with rather 
indistinct dusky edgings; a round, brownish-black spot somewhat larger than eye, just above base of 
pectoral; dorsal narrowly edged with black, the border widening on posterior edge to form a well- 
marked spot; anal narrowly bordered with pearly white, posterior part of fin blackish; spine and first 
ray of ventral pearly white; caudal with upper and lower borders dusky, the lower part much the 
darker, the central area yellowish ; pectorals immaculate. 
Color in life, bright reddish orange, posterior two-thirds suffused with dusky; spot above pecto- 
ral brownish black; preopercular spine dark blue; dorsal and anal colored like body, the dorsal 
narrowly edged with black, the black spot on posterior part with an indistinct boundary; anal with a
