about 4 in eye. Lips little developed, narrow, firm. Teeth fine, 

 even, short, in moderately wide bands in jaws. Narrow band of 

 similar teeth over vomer to each palatine. Tongue free, depressed, 

 smooth, rounded in front. Front nostril simple pore nearly midway 

 in snout length and hind nostril little larger, close before front eye 

 edge. Interorbital with slight furrow each side in front, slightly 

 convex behind. Preopercle ridge entire, and hind edge minutely 

 serrate. Opercle with 2 small spines along hind edge. 



Gill-opening extends forward about opposite front pupil edge. 

 Rakers iv, 1 + 10, iv, lanceolate, slender, twice length of filaments 

 or 2 in eye. Pseudobranchise long as gill-filaments. Isthmus long, 

 constricted forwards, and with deep trenchant keel over greater 

 portion anteriorly. 



Scales large, at present mostly fallen, finely ctenoid, and apparently 

 in lengthwise rows. Head scaly, and evidently 2 rows of large 

 scales on cheek. Occiput with number of mucous channels. Appar- 

 ently scaly flap between ventral bases. At present no axillary 

 ventral scale. Caudal base scaly, otherwise fins naked. Lateral 

 line apparently complete, and largely concurrent with dorsal profile. 

 Tubes? Suprascapula entire. 



Spinous dorsal inserted about opposite pectoral origin, fourth 

 spine longest though little longer than third or fifth, second and 

 sixth subequal, and first much shorter than seventh. Soft dorsal 

 inserted about midway between eye centre and caudal base, second 

 ray highest, and depressed fin 1| to caudal base. Spinous anal 

 inserted opposite soft dorsal origin, first spine about 5 in second. 

 Soft anal like soft dorsal, though much lower, 1| to caudal base. 

 Caudal (damaged) apparently rounded. Pectoral moderate, reaches 

 about opposite last basal fourth of soft dorsal. Ventral origin 

 slightly before pectoral origin, fin reaches soft anal origin and ventral 

 spine but little short of spinous anal origin. Vent about opposite 

 last seventh of depressed ventral spine. 



Color in alcohol rather dark chocolate-brown generally, pockets 

 of fallen scales deeper brownish. Except pectorals all fins blackish- 

 brown, very dark and without spots or markings. Pectoral pale 

 brown. Muzzle and mandible slightly paler than rest of head. 

 Iris dull slaty.
