()44 BtTLLETIN OF THE HNITED STATES FISH COMMISSION. 



tine bands abutting against tin- pustMior end ut' each lateral hall'; ]msteriui- notitril a l■^)Undi^^h or oblong 

 pore in niidille of length of snout; anterior nostril a round pore in a short tul)e, which is prolonged at 

 the inner side to form a tiap, and is separated from posterii.ir nostril by I length of snout; the narrow 

 interorbital width gently concave; gill-membranes separate, the right side overlapping, the anterior 

 end of gill-slit well in advance of eye; l.inuichiostegal rays 7; large pseudobranchia* i)resent; gills 4; 

 posterior series of tilameuts on fourth arch shortened; a wide slit behind fourth arch; gill-rakers 

 siendei-, toothed, l:i in nund)er on liorizontal liud) of outer arch, the longest one-fourth diameter of 

 eye; angle of jucojierclc- with - closely apposed short spines, the angle projecting, the margin above 

 angle concave. As in others]iecies, there are 2 opercular spines and one subopercular s]iine, the latter 

 and the upper o]iercular spine of equal length, the lower opiTCular spine shorter; a single strong 

 suprascapular spine above origin of lateral line; the 5 anterior scales of lateral line bear each a strong 

 median crest on the suunnit of the tube, but are not armed with spines. 



Origin of sjiinous donsal above ti]) of opercular flap, its distance from tip of sn<jut :-lS huudredtlis 

 of length to base of caudal; spines very slender and flexible, the anterior produced far beyond outline 

 of tin, forming a filament which extends to base of third ray of scjft dorsal and is 19 hundredths of the 

 length; second s]>ine ( l.'l hmidredths) when declined reaching tips of last 2 spines, and well separated 

 from first dorsal ray; thii-d and fourtrj spin<'S, w hen declined, failing to reach tips of last spines; out- 

 line of lin slightly coTicave; liist ray of soft <lorsal longest ( IL' hundredths), and forked at tiji as are all 

 succeeding rays; last ray cleft to base; distance (t).5 hundredths) between last dorsal spine and lirst 

 soft raj' is two-tiftlis occupied by the membrane from the spine; anal tin Ijeginning slightly before ilor- 

 sal anil ending slightly beliind it, all the rays simple except the last, which is cleft to base; caudal 

 gently rounded; middle i.)ectoral rays longest ( 19 hundredths) , their tips reaching vertical from second 

 dorsal ray; ventral spine ((1.5 huudredtlis) stnjng and curved, well sejiarated from adjoining ray by 

 movable membrane; fourth ventral ray longest (U..") humlredths), reaching half the distance from its 

 base to se('ond anal ray. 



Scales caducous and lost over the greater part of the head and body, most persistent along lateral 

 line; they are thickly beset with short spines on margins, their exjpo.sed suifaci-s maiked with line con- 

 centric lines, which center near the free margin of the scale; scales smooth on breast and abdomen and 

 along base of anal; their character on head can not lie determined; a single series of scales on [iroximal 

 part of dentary, one series on maxillary; the gulai' and gill mendiranes, and a narrow median frac-l on 

 anterior half of snout naked; rest of head closely scaled. 



Lateral line first curved upward toward origin of spinous dorsal, then gently decurrent, reaching 

 its lower level opposite fourth anal ray; 5 or 6 scales between lateral line and front of soft dorsal; 4 

 s<'ales between lateral line and middle of anal base; 9 series of scales betwi-en occiput and first dorsal 

 spine. 



t'olor in spirits, light olive brow n on body, grayish on ■ii>ut, snout and opercles; upper pari of 



eye black; iris margined with green in front and behind; a golden-green spot on anterior jiart of jire- 

 opercle, a fainter one on the Hap; very faintly marked greenish yellow blotches on back cipjiosite third 

 dorsal sjiine, third dorsal ray, and ninth dorsal ray; on lower half of side 9 conspiiaious purjilish dusk}' 

 liands, narrower than the interspac'es, running obliquely downward and forward, and reaching to or 

 almost to base of anal; two of these bands are in front of anal fin, and d(.i not reach midvenfral line; 

 on dors;U half of body, these l)ars become obscure ami the pattern is not evident; 2 or .'! of them, 

 under soft dorsal, fork just above the lateral line, the lii'anches diverging widely and reaching base of 

 dorsal; anterior half of spinous dorsal black; soft dorsal with a vertical blackish streak lengthwise of 

 distal half of each inteiiadial nieinbrane, becoming more intense toward margin of fin; tips of rays 

 white; anal uniforndy dusky; middle caudal rays whitish, dusk}' toward margin, with narrow whitish 

 tips, the upjierand lower rays dusky; a poorly defined small black spot on basal portion of some of the 

 ujiper rays; pectorals dusky with liLrhter liase and margin; ventral membrane blackish in distal por- 

 tion, the rays white. 



In the cotype, r>',', mm. long, from station 4079, northeast coast of Maui, depth 14:! to 17H fathoms, 

 the fin rays are as follows: Dor.ual vi-lT); anal 17; pectoral 27; ventral i, 5; scales 59 to (i2. In this 

 immature specimen, the first dorsal spine scarcely jirotrudes beyond theolbei' s])ines, the bars are 

 confined to a series of short blotches along lateral line, an<l the black spot nc^ai- base of upjier i-aiulal 

 lavs is very intense and cons|iicuous, oblong-oval, and ocellaled willi whilish; perilipueum jet-black. 

 Two specimens obtained.
