in front of upper and along rami of manclible posteriorly, where also 

 in but 2 rows on each ramus. Latter but little elevated inside 

 mouth. Bands of much smaller teeth across vomer and on each 

 palatine. Buccal folds moderately broad in mouth. Tongue 

 depressed, smooth, free, and attenuated. Nostrils close together on 

 side of snout, also close before front eye edge, front one with short 

 tube and short cutaneous flap behind. Preorbital narrow, 2| in eye. 

 Interorbital slightly convex. Preopercle edge slightly convex 

 behind, finely serrated and with about 5 enlarged denticles around 

 corner. Opercular spines 3, median largest, closer to lower and 

 little posterior. 



Gill-opening extending forward opposite front eye edge, and 

 uppermost edge but slightly inclined from horizontal. Rakers 

 IV, 3+9, IV, lanceolate, and longest about equal gill-filaments or 

 2f in eye. Pseuclobranchiae about f of gill-filaments. Isthmus 

 broad, bevelled in front, with slight keel behind. 



Scales all finely ctenoid, largest on trunk, smaller along body 

 edges, especially predorsal, breast and belly. Very small scales on 

 head above, with crowded smaller ones basally, these also extend 

 over postocular and suborbital regions, and cheek. Small scales 

 also crowded about upper part of opercular flap. Very small scales 

 over mancUble, and about 10 rows on maxillary.- Scales on trunk 

 in more or less horizontal rows, crossing lateral line. Minute scales 

 over basal portions of all fins more or less. Pectoral axil with pit, 

 sheathed above by broad flap covered with small scales. Though 

 of irregular size scales on cheek in about 25 rows from eye to lower 

 preopercle angle. Lateral line of simple inclined tubes little exposed, 

 and its course nearly concurrent with dorsal profile, out on caudal 

 base medianly. 



Spinous dorsal inserted little nearer snout tip than origin of soft 

 dorsal, spines graduated down from third which longest, edge deeply 

 notched with cutaneous point behind each spine tip. Soft dorsal 

 inserted midway between spinous dorsal origin and caudal base, 

 fin oblong, rounded in front and behind. Spinous anal inserted 

 little nearer ventral origin than caudal base, second spine longest, 

 third but little shorter, and first | of second. Soft anal rounded, 

 also caudal. Pectoral broad, reaches about f to anal, and mechan 

 rays longest. Ventral inserted close behind pectoral base, depressed 

 fin reaching f to anal, and spine about f fin length. Vent at first 

 third in space between depressed ventral tips and anal origin.
