Depth 14% to end of tail ; head S% ; disk length V/q in its width, 

 tail less than disk. Snout 1% in head, moderately long, produced in 

 rather broad tip ; eye 9, 6% in snout, 3 in interorbital ; dentary width 

 2% in head; teeth in 44 rows in jaws, small, each with low cusp; 

 nostrils small, front valve moderate, internarial equals dentarj' 

 width ; interorbital 3, depressed concavely. Gill openings small, sub- 

 equal, equidistant. Spiracle slightly less than eye, deep, broad, edges 

 entire. 



Skin above rough to touch, asperities large on end of snout and 

 rostral cartilages terminally, before each eye and in interorbital; 4 

 large tubercles along superciliary edge, besides smaller one outward 

 and directly before eye ; large occipital tubercle ends in sharp-pointed 

 spine, followed by smaller one; from above ventrals row of strong 

 vertebral tubercles, 24 to first dorsal and 2 more in interdorsal space ; 

 sides of tail roughly asperous. 



First dorsal broad, length 5 in head; second dorsal 5i/^, similar; 

 moreover the body appears much rougher.

Head to first gill opening nearly 5 in total length; disk length 

 ll^ its width, 2 in total length. Snout 1% in head, forms slightly 

 obtuse angle with end somewhat projecting; eye 5, 2% in snout, 2^ 

 in interorbital; mouth width 2% in head, but very slightly arched; 

 teeth pointed in both sexes, more so in male than in female ; nostrils 

 rather large, internarial 3 in head, broad flap at each mouth corner 

 with hind edge fringed; preoral length li/^ in head; interorbital 

 1%05 cartilaginous firm region wide as orbit length. Spiracle large, 

 oblique, close behind eye, slightly less than eye. 



Curved spine in front and behind each orbit ; 4 to 6 similar spines 

 in triangle in middle of back; tail with median series of 16 to 18 

 spines, only very small ones on sides; these spines present in both 

 sexes, young and old ; in male greater part of body above smooth, 

 with usual patch of recurved spines near pectoral angle; in female 

 whole upper surface covered with scattered, small, stellate asperities, 

 still more numerous in young; caudal series of spines in young 

 usually continued forward to dorsal spines. 



Dorsals close together, posterior little larger, 2% in head, inter- 

 dorsal narrow notch; pectorals form rhomboid disk, front edges
