Head nearly one fourth of the length from snout (o cud of .second dorsal, 

 equal to two fifths of the length of the second dorsal base; ('(juals more than 

 the depth of the body, or to nearly four times the length of the (U'iMt. First 

 dorsal rather small, spine reaching the origin of the second doi'sal. Height of 

 second dorsal about eciual to that of the orbit; upper margin not concave. 

 Caudal filament more than twice as long as the head ; caudal fins narrow, hardly 

 one third of the length of the orbit in width. Anal fin narrow, small, distinctly 

 separated from the subcaudal. Pectorals wide, reaching behind the bases of 

 the ventrals, hind margins slightly concave. Outer angles of the pectorals and 

 the ventrals ratlwn' sharp. Claspers of male twice as long as the venti-al fin; 

 divisions extending more than half th(Mr length. Waves in the lateral line along 

 the flank short and shallow. The supracaudal fin is a very little deeper but 

 much shorter than the subcaudal; the latter being coiilinued for a long distance 

 below the filament. 



Greyish brown, somewhat streaked or blotched longitudinally on the flanks; 

 with or without small spots or vermiculations of darker near the bases of the 

 dorsals. Several streaks of darker on the caudal section. Lateral line dark.

Head approximating one fifth of the length from snf)ut to end of second 

 dorsal, little less than one third of the length of the base of the latter fin. Second 

 dorsal not indented on the upper bonier. Pectorals reaching behind the bases 

 of the ventrals. Anal not distinct. Caudal filament more than three times the
