Depth IG14 to subcaudal origin; head 3% to 3%; disk width 

 ly^ to ly^ its length. Snout ly^ to 1% in head, long, tapers to 

 point; eye 7% to IQi/^ in head, 514 to 9% in snout, 21/5 to 3l^ in 

 interorbital ; dentary width 3% to 4 in head, with 3 very short or 

 rudimentary grooves at each angle; teeth in 30 to 34 rows in jaws, 

 80 to 84 rows with age, smooth, rhombic; nostrils moderate, length 

 2% in dentary width or nearly 1 to li^ in internarial width; front 

 nasal valve reaches halfway from its lobe to iimer edge of nostril 

 and very little turned forward at end; hind nasal valve larger and 

 outer section much shorter than inner; interorbital 375 to 4% in 

 head, depressed, or nearly level medially, orbital edge elevated little 

 anteriorly and above spiracles. Gill openings subequal, equidistant. 

 Spiracle large, deep, close behind eye and without fold on hind edge. 



Body rather rough, tubercles all rather large, 2 or 3 before each 

 eye, 1 or 2 above spiracle and 23 principal large vertebral tubercles 

 before first dorsal, also 3 interdorsal vertebral ones besides 2 well 

 spaced at shoulder. Tubercles inconspicuous with age. 



First dorsal broad, front edge 2% to 31/5 in head; second dorsal 

 similar, 3 to 31/5 in head; caudal 2% to 2%, subcaudal without lobe, 

 moderately low; pectoral broader posteriorly; ventral length 1% 

 to l%o in head. 



Back largely uniform brown, pale or creamy translucent space
