times, interorbital width 1\ times ; mouth subinferior, its width 

 3f times in length of head ; lips moderately developed, lower with 

 a small median lobe ; two barbels on each side, anterior about 

 f diameter of eye, posterior slightly longer than eye. Dorsal IV 9, 

 situated nearer to root of caudal than to eye, border concave ; last 

 simple ray slightly enlarged, bony, flexible, segmented down to its 

 basal third, nearly as long as head. Anal III 5, reaching caudal. 

 Pectoral nearly as long as head, not reaching ventral ; base of latter 

 below anterior rays of dorsal. Caudal peduncle \\ times as long as 

 deep. Scales longitudinally striated, 30 4-, 1\ between lateral line and 

 ventral, 14 round caudal peduncle. Silvery, darker above than below; 

 distal extremity of dorsal dark. 



Total length 178 millim.

 Snout obtuse, a little more than 3 times in length of head, eye 7 times, 

 interorbital width a little more than twice ; mouth inferior, its width 

 nearly 2| times in length of head : lips much developed, lower uninter-

 anterior slightly shorter than eye, posterior slightly longer. Dorsal III 9, 

 a little nearer occiput than root of caudal; last simple ray flexible, not 

 enlarged, a little over f length of head. Anal III 5, not reaching 

 caudal. Pectoral § length of head, not reaching ventral ; latter below 

 middle of dorsal. Caudal peduncle nearly If times as long as deep. 

 Scales longitudinally striated, 25-26 $x, 2 between lateral line and 

 ventral, 12 round caudal peduncle. Brown, darker above ; each scale 

 with a darker base and a lighter edge. 



Total length 500 millim.
