dorsal, and edges convexly rounded. Caudal peduncle compressed, 

 length about f its least depth. 



Head compressed, moderate, rather flattened sides evenly con- 

 verging above and below. Snout wide, profile about straight, 

 surface convex, and length | its width. Eye rounded, little elevated, 

 hind pupil edge nearly midwaj^ in head length. Mouth small, short 

 gape slightly oblique, and jaws about even. Lips rather narrow, 

 fleshy. Maxillary extends back nearly opposite eye. Teeth small, 

 simple, compressed, but little pointed, crowded to form nearly even 

 cutting-edge in single row. No teeth on mouth roof. Tongue 

 tliick, pointed, free in front, smooth. Inner buccal folds broad. 

 Mandibular rami rather well elevated inside mouth. Nostril simple 

 pore slightly behind middle in snout length. Interorbital convex. 

 Preorbital width 2 in eye, slips over most of upper maxillary edge, 

 and hind edge with 2 short spines directed back. Suborbital edge 

 finely serrate below. Preopercle edge obliquely forward not quite 

 opposite eye center, finely serrate except several broader serrse at 

 lower portion, and lower edge entire. Opercle with 2 short blunt 

 points. 



Gill-opening forward opposite front pupil edge. Rakers 8-t-15, 

 lanceolate, longest | of filaments, which If in eye. Pseudobranchise 

 long as gill-filaments. Branchiostegal membrane narrowly over 

 short constricted isthmus. 



Scales finely ctenoid, narrowly imbricated, in even lengthwise 

 rows, smaller along body edges and fin bases. Vertical fins finely 

 and closely scaled over basal portions. Suprascapula entire. Cheek 

 with 3 rows of scales. Lips, chin, preorbital, suborbitals and narrow 

 edge of snout naked. Scales on snout above and top of head all 

 small. Upper arch of lateral line concurrent with limit of general 

 squamation on dorsals, extends back opposite twelfth dorsal spine 

 base, though follow by 3 more pores till below front of soft dorsal. 

 Tubes simple, large, well exposed or over first half of scale exposure. 

 Pores in straight section simple, inconspicuous, one in center of each 

 scale exposure, and not on caudal base. 



Spinous dorsal origin opposite that of pectoral, spines graduated 

 up to fourth, after which subequally long to last, and fin edge notched 

 with cutaneous flap from behind each spine tip. Soft dorsal inserted 

 at last third between suprascapula and caudal base, fin rounded, 

 with median rays longest. Spinous anal inserted about midway 

 between pectoral origin and caudal base, first spine nearly f of 

 second. Soft anal like soft dorsal. Caudal a little emarginate
