Head to spiracle 6 in total length; disk length 1% its width, tail 

 about % disk length. Snout II/3 in head to spiracle, broad, not ex- 

 tended at tip, angle slightly obtuse ; eye 7 in head to spiracle, 4V^ in 

 snout, 3 in interorbital ; interorbital 2i^ in head to spiracle, broad, 

 concave. Spiracle little oblique, close behind eye, equals eye. 



Both upper and lower surfaces naked; only few minute spines or 

 prickles present along front and hind borders of pectorals, on snout 

 tip and on front and hind portions of orbit ; 3 strong spines on mid- 

 dle of back in male, only 2 in female; 2 strong scapular spines, one 

 each side of median line, in male as in female; no spines on middle 

 of disk ; tail with median row of 22 to 26 spines, wide band of coarser 

 minute prickles on each side; under surface without spines and 

 prickles. Wide lateral fold along each side of tail. Erectile pectoral 

 spines well developed, usually radial, in 22 or 23 series and at most 6 

 or 7 hooks in series. 



Dorsals high, subequal, about 2% in head to spiracle, interdorsal 

 very narrow deep notch, with spine in females; pectorals form 

 broad rhomboidal disk, front edge broadly notched medially, outer 

 and hind angles broadly convex ; ventrals deeply notched. 



Light brown above, whitish below, no spots or blotches. Length, 

 1,077 mm. (Soldatov and Pavlenko.)

 in interorbital; mouth width 1% in snout, scarcely undulate; teeth 

 small, rounded, about 45 rows above ; nostrils confluent with mouth,
