Depth 141/2 to 17% to subcaudal origin ; head 3 to 3%, disk width 

 114 to 1% its own length. Snout 1% to 1% in head, long, pointed ; 

 eye S% to 12%, 7^4 to 9 in snout, 3 to 4 in interorbital ; dentary 

 width 3% to 3% in head, with short upper and lower labial folds 

 at each angle; teeth in 53 to 60 rows, smooth, rhomboid; nostrils 

 large, wide, oblique, narrowing posteriorly, each % dentary width; 

 valves feeble, with short anterior lobe; internarial width 1% to 1% 

 in nostril; interorbital 3 to 3I/2 in head, depressed. Gill openings 

 nearly equidistant, last shortest. Spiracle close behind eye, small, 

 hind edge with 2 obscure papillae. 



Above rather coarsely tuberculate, rough to touch. Eow of fine 

 supraorbital tubercles, extending continuously" over spiracle. About 

 19 to 30 larger vertebral tubercles to first dorsal, interdorsal smaller; 

 cluster or patch of several slightly enlarged tubercles on each 

 shoulder. 



First dorsal pointed, front edge 2% to dy^ in head; second dorsal 

 like first, front edge 2% to 31/10; caudal 1% to 2^3, subcaudal moder-
