Diagnosis.— D X,ll; P 14; A III,6; gill rakers 3+11; scales below ID origin about 5, below 
2D 4+1+8 or 9, pored lateral-line scales 44; circumpeduncular scales 1+9+1+10 (21 total). Anteri¬ 
or nostril tubular, rim greatly elevated posteriorly and bearing about 7 or 8 long cirri at tip. Scales 
all cycloid (except for a hard, sharply spinulated suprascapular scale bone above the upper open¬ 
ing of the gill cover). Caudal fin weakly emarginate, upper and lower lobes about equal. Interradi- 
al membranes of soft dorsal and anal fins scaly on basal one-half to one-third. Nape, opercle, 
preopercle, interopercle, mandibular ramus, pectoral-fin base, and chest covered with cycloid 
scales. A bold black spot between last three spines and first soft dorsal ray formed above broad 
black saddle on dorsal half of body. 
Description.— Head and body laterally compressed, greatest width of head 6.3 times in SL, 
greatest body width 5.9 times in SL. Snout pointed, longer than orbit diameter; interorbital space 
narrow, bony width about 60% of greatest orbit diameter. Orbit about 4 in HL; pupil sharply egg- 
shaped with pronounced anterior aphakic (lensless) space. Jaws equal; posterior margin of maxil¬ 
la below middle of orbit. Two broad, flat, weak opercular spines developed, the dorsal spine 
partially obscured by skin and scales, lower spine more prominent and forming posterodorsal 
comer of gill cover. Anterior nostril tubular, rim low anteriorly but elevated into a long flap poste¬ 
riorly, the flap fringed with 7 or 8 long cirri, a few filaments longer than height of flap. Gill open¬ 
ing ventrally extending forward to about vertical passing through hind edge of orbit. Gill rakers 
relatively short, stout and recurved, the uppermost on lower limb (ceratobranchial) about 1.5 mm 
in length, the succeeding rakers gradually shorter with last three or so tubercular. About 11 pseudo- 
branchs. 
Spinous dorsal fin with middle spines longest, a prominent dip between spinous and soft-rayed 
portions of dorsal fin; the longest dorsal spine shorter than longest dorsal soft rays. Size and shape 
of pectoral fin could not be determined owing to left fin tom off in capture and right fin cut off for 
tissue sample. Pelvic fin below fourth spine of dorsal fin and behind origin of pectoral fin, its tip 
when depressed not extending to origin of anal fin. Anal fin with three strong spines, the first about 
half length of second, which is slightly longer than third spine; six soft rays forming narrow round¬ 
ed tip to fin. Caudal fin weakly emarginate. 
Scales all cycloid (excepting a hard, sharply spinulated suprascapular scale bone above the 
upper opening of the gill cover). Snout and dorsal surfaces of head naked anterior to a vertical pass¬ 
ing through hind margin of preopercle. Interopercle finely scaled anteriorly and dorsally immedi¬ 
ately below preopercular margin. Mandibular ramus with tiny thin scales covering most of poste-
