large, circular, next to upper profile, and liead center in length nearly 

 at hind eye edge. Mouth large, rather well inclined, and closed 

 lower jaw included within upper. Maxillary large, well inclined, 

 nearly straight and reaches past eye center about to hind pupil edge. 

 Terminal maxillary expansion 2 in eye, slightly emarginate behind, and 

 whole upper maxillary edge slips below preorbital. Latter mod- 

 erate, width 3 in eye. Lips moderate, fleshy, firm. Teeth fine, 

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

 vomer to and on each palatine. Tongue free, depressed, smooth, 

 rounded in front. Inner buccal folds rather narrow. Front nostril 

 short inconspicuous tube about midway in snout. Hind nostril 

 moderate pore close before, and nearer eye, than front nostril. Inter- 

 orbital generally depressed, with slight furrow each side. Preopercle 

 ridge entire, hind edge finely serrate. Opercle with single small 

 spine. 



Gill-opening forward about opposite hind nostril. Rakers ii, 

 4-fl2, II, rather robust, lanceolate, nearly long as filaments, which 

 3 in eye. Pseudobranchise about long as filaments. Isthmus long, 

 constricted forward, and with median keel, especially trenchant 

 forward. 



Scales large, finely ctenoid, above lateral line in rows parallel 

 with its course, and below in horizontal rows. Head scaly, cheeic 

 with 2 rows, and opercles with moderate scales. Head above and 

 mandible with numerous mucous channels. Large scaly flap between 

 ventral bases about f length of fin. Axillary ventral scale mod- 

 erate, rounded. Caudal base covered with small scales, fins other- 

 wise naked. Lateral line complete, largely concurrent with dorsal 

 profile. Tubes simple, extend well over scales, large, and with 

 appearance as if located on small obscure accessory scale. 



Spinous dorsal inserted slightly behind pectoral origin, or about 

 midway between snout tip and middle of last depressed dorsal ray, 

 all spines slightly curved, third longest, second little longer than 

 seventh, and first very short. , Soft dorsal inserted nearly midway 

 between hind eye edge and caudal base, spine f of fin, and depressed 

 fin If to caudal base. Spinous anal origin about opposite that of 

 soft dorsal, and with soft anal much smaller than soft dorsal, though 

 reaches about as far posteriorly. First anal spine about I length 

 of second. Caudal broad, slightly emarginate behind, and lobes 

 rounded. Pectoral broad, not quite to anal origin. Ventral inserted 

 well before pectoral origin, fin depressed f to anal origin, spine about 

 y in fin. Vent little nearer depressed ventral tip than anal origin.
