\ more than diameter of orbit. Teeth in jaws minute asperities in 

 rather broad band-Hke patches which are not confluent anteriorly. 

 Similar patches on palatines. Vomer edentulous. Tongue large, 

 thick, rounded and a little free in front but without asperities. Nos- 

 trils moderately large, rounded, similar, together, lateral and posterior 

 on snout and directly in front of eye. Interorbital space broad, convex, 

 and posteriorly to occipital region becoming more convex. 



Gill-opening extending forward till below posterior portion of orbit. 

 Gill-rakers small, slender, somewhat clavate, 13 + 18, and longest a 

 little longer than longest filaments and a trifle more than distal ex- 

 panded maxillary extremity. Pseud obranchiaj small. Isthnuis broad 

 and convex. 



Scales rather small, mostly finely ctenoid and small ones extending 

 over most of fins and head. On spinous dorsal, pectoral and ventral 

 they are present only on basal regions, and other fins almost completely 

 covered. Those on head small about and on snout. Head scaly with 

 exception of lips and branchial flaps. Ax;il of pectoral with a fleshy 

 flap and a thin pointed scale above. Axil of ventral with a grooved 

 scaly flap. Lateral line continuous, of simple tubes, a little high at 

 first and then running down along middle of side of caudal peduncle and 

 well out on caudal. 



Spinous dorsal inserted about midway between tip of snout and mid- 

 dle of base of soft dorsal or a trifle behind origin of ventral, spines 

 slender, and second spine a little longest. Soft dorsal inserted a little 

 nearer base of caudal than eye, and first branclied ray highest. Anal 

 similar to soft dorsal, inserted behind origin of same fin and a little 

 nearer that of pectoral than base of caudal, and first branched ray 

 highest. Caudal large, forked and lobes pointed. Pectoral long, sec- 

 ond simple ray longest and reaching origin of anal. Pectoral filaments 

 very long, first and third longest, and latter longer than entire 

 length of fish. I^owest and shortest pectoral filament about equal to 

 head without snout. Ventral with first ray longest and reaching about 

 f of space to anal. Insertion of ventral a little behind origin of pecto- 

 ral. Vent close before tip of depressed ventral. 



Color in alcohol mostly very pale brownish-white or pale browni:?h. 

 Back darker brown with minute pale dusky dots on side of head and 

 above pectoral. Dorsals and caudal sprinkled with similar pale dusky 

 or gray dots and also slightly darker than other fins. Upper margins of 

 dorsals slightly darker. Other fins like abdomen, except pectoral 

 which is deep livid black on outer §. Pectoral filaments pale, like fin 

 at base, soon becoming gradually browner till colored like back. Sid<^
