xiii; caudal with 6+5 branched rays; pel vies 1,5; gill rakers about 

 5-f-l +8; number of vertical scale rows from upper edge of gill opening 

 to midbase of caudal fin 43 to 45, and 22 to 24 pores in lateral line. 



Depth 2.5 to 2.8, head 2.2 to 2.3, both in standard length. Snout 

 3.2 to 3.3, eye 5.0 to 7.0, postorbital part of head 1.8; least depth of 

 caudal peduncle 3.5 to 3.8, longest ray of pectoral fin 1.5 to 1.6, 

 longest dorsal spine 3.0 to 3.8, all in length of head. Least width of 

 bony interorbital 0.7 to 0,9 in eye; least depth of caudal peduncle in 

 its length 1.4 to 1.5; next to last dorsal spine in last dorsal spine 1.3 

 to 1.7 and in longest dorsal spine 1.4 to 1.8; length of first anal spine 

 in second 1.9 to 2.1 ; pelvics reach to or a little past vent but not quite 

 to anal fin origin. 



Body covered with ctenoid scales, mostly lacking on head, except 

 on the operculum. Numerous dermal cirri almost everywhere on 

 head and body, but especially well developed on dentary, maxillary, 

 preorbital, preopercle, operculum, along lateral line, and on various 

 body scales; a large dermal cirrus at midbase of caudal fin; second anal 

 spine equal to or a little longer than third, both about same thickness; 

 tip of upper jaw with scarcely any concavity at symphysis, but tip of 

 lower with distinct symphyseal knob projecting slightly beyond 

 profile of snout; palatine teeth absent; a distinct pit below eye; area 

 at anterior part of base of spiny dorsal with a high camel-like hump 

 (composed of muscular tissue that appeared normal) ; rays of soft dorsal 

 notably longer than dorsal spines; no spmes exposed at base of caudal 

 fin; cranial spines exceedingly well developed and becoming many- 

 pointed with increase of age, some serrate in form; preorbital with one 

 spine directed forward and another main spine downward and back- 

 ward. 



Color in alcohol. — Head and trunk generally barred and blotched 

 with blackish and pale areas; a black barlike blotch extends from above 

 pectoral fin base and rear of head dorsally, covering the hump and the 

 dorsal fin from third to fourth or fifth spme; a second prominent 

 blackish irregular bar extends from soft dorsal fin across body, includ- 

 ing basal three-fourths of anal fin ; base of caudal fin rays blackish, and 

 another dark bar across middle third of caudal fin, with distal fifth of 

 that fin pale; pectoral blotched with blackish, mostly forming two 

 dark irregular bars across it, with tips and center of fin paler; pelvic 

 fins with central area black, distal fifth of margin white; buccal mem- 

 brane between premaxillary teeth and area inside these teeth at 

 symphysis of upper jaw black with a median white line; axil of pec- 

 toral fin with a black spot and sometimes a few additional black dots.
