snout length and hind one Kttle larger, elevated, close before eye 

 above. Interorbital about level. Preorbital width narrow, entire 

 slightly less than a third of eye. Preopercle edge minutely den- 

 ticulate, with slight indenture above angle. Opercle ends in 2 

 rather weak points. 



Gill-opening forward beyond front pupil edge though not quite 

 to front eye edge. Rakers 8+16, lanceolate, robust, nearly half 

 of eye-diameter. Gill-filaments short, about f of rakers. Pseudo- 

 branchiae very large, about long as rakers. Isthmus narrowly 

 constricted, with groove in front. 



Scales all finely ctenoid, smaller on breast, predorsal, edges of 

 caudal peduncle, and head above. Above lateral scales in sUghtly 

 inclined rows to dorsal profile, below in horizontal rows. Most of 

 head scaly, except muzzle and broad rim around eye. Front of 

 interorbital naked and squamation from occiput forward about 

 opposite center of eye. Cheek with 5 rows of scales to preopercle 

 ridge, and on preopercle flange row of broad scales with several 

 smaller, scattered irregular scales. Subopercle, interopercle and 

 opercle scaly, also sides of head above. Caudal covered with small 

 scales, also bases of soft dorsal, anal, pectoral and ventral. Pointed 

 free axillary ventral scaly flap, 2| in fin. Lateral line complete, 

 largely concurrent with dorsal profile, tubes simple and little exposed. 

 On side of caudal peduncle lateral line little superior at first, median 

 at caudal base. 



Spinous dorsal inserted little behind pectoral origin, or little nearer 

 soft dorsal origin than snout tip, spines long and slender, fourth 

 longest and others graduated down, fin edge apparently little notched. 

 Soft dorsal origin nearer caudal base than spinous dorsal origin, fin 

 low, rounded or convex, last ray not produced, and not quite reaching 

 caudal base. Anal begins about opposite soft dorsal origin, third 

 spine longest with second little shorter, rayed fin little higher in 

 front than soft dorsal and not extended so far posteriorly. Caudal 

 moderate, hind edge very slightly emarginate. Pectoral long, 

 falcate, reaches vent. Ventral inserted close behind pectoral base 

 or but slightly before spinous dorsal origin, reaches 1^ to anal, spine 

 1^ in fin. Vent midway between ventral tips and anal origin. 



Color in alcohol uniform pale brownish, fins scarcely tinted darker. 

 Iris slaty. 



Length 162 mm.
