in profile, convex over surface, lengtli about | its width. 'Eye large, 

 round, close to upper profile and hind pupil edge midway in head 

 length. Mouth slightly inclined, jaws about even, gape short. 

 Maxillary reaches about first f in space between nostril and eye, 

 entirely slips below broad preorbital. Teeth as row of rather even 

 crowded compressed incisors, as single cutting-edge, and each tooth 

 with end rather broad, or truncate, though slightly emarginate 

 medially. No teeth on roof of mouth or tongue. Inner buccal folds 

 broad. Tongue free, pointed and depressed. lips moderately 

 broad. Nostril simple pore slightly before middle in snout length. 

 Interorbital convex. Preorbital width Ij in eye. Hind preopercle 

 edge slopes well forward or about opposite eye center, and both it and 

 preopercle ridge, also preorbital edge, entire. 



Gill-opening forward about opposite hind maxillary end. Rakers 

 31+45, lanceolate or very slender, 1| in eye. Gill-filaments 2 in 

 eye, pseudobranchise equally long. Isthmus narrowly constricted 

 forward with narrow branchiostegal membrane. 



Scales ctenoid, narrowly imbricated, in even lengthwise rows, 

 smaller along body edges. Fins all scaly basally. Suprascapula 

 thin, entire. Cheek with 2 rows of scales. Scales on opercles mod- 

 erate and small on top of head. Lips, preorbital, suborbitals and 

 front edge of snout naked, also front of mandible. Scaly flap between 

 ventral bases barely half of spine, and pointed axillary ventral scale 

 about f of spine. Height of large humeral scale equals eye-diameter. 

 Lateral line with upper branch curving up at first and then follows 

 concurrently along back with upper limits of general squamation 

 to end below front of soft dorsal. Tubes simple, large, over first 

 half of each scale exposure. Pores in horizontal section small and 

 inconspicuous, and one in middle of each scale exposure, not on 

 caudal base. 



Spinous dorsal inserted opposite pectoral origin, spines rapidly 

 graduated up to third or fourth, then slightly so to last, fin edge 

 well notched, and cutaneous flap from each spine tip behind. Soft 

 dorsal origin little before last third in space between pectoral origin 

 and caudal base, rays graduated to seventh, which longest and forms 

 pointed tip behind reaching back half-way in caudal. Spinous anal 

 origin midway between that of pectoral and caudal base, first spine 

 f length of second. Soft anal graduated to seventh raj^, fin pointed 

 behind like soft dorsal. Caudal (damaged) apparently truncate 

 behind, broad. Pectoral moderate, 1^ to anal, upper rays longest. 

 Ventral inserted about opposite middle of pectoral base, spine f
