Depth 21/4 in snout ; head to first gill opening 2 in length to vent. 

 Snout V/s in head to spiracles, produced in short point; eye 2% in 

 snout, 1% in interorbital ; mouth width 1% in preoral length; firm 

 interorbital 2% in snout. 



Before each eye strong divergent spines and 1 close behind ; strong 

 median vertebral spine li/4 in eye; down back of tail row of 10 

 spines to first dorsal, also spine between dorsals. 



First dorsal opposite middle of tail; pectorals form disk length 

 11/4 in its width, front angle obtuse, front edges slightly undulate; 

 tail to base little longer than disk length, II/3 in disk width. 



Above chocolate, with variable scattered neutral dusky spots, few 

 or obsolete toward disk margins and none oscellated. On caudal 5 

 transvei-se neutral dusky bands or blotches. Below whitish, margin 

 of disk grayish.

Head to spiracle 7 1/^ in total ; disk length ll^ its width, tail slightly 

 longer than rest of body. Snout li^ in head measured to spiracle, 

 blunt, hardly produced, angle very obtuse; eye 3% in head to spir- 

 acle, 2% in snout, 2i/^ in interorbital; teeth in numerous rows, square 

 based and sharp pointed; 3 suprascapulary spines each side from 

 region 3 rows of large stellate-based spines extend all space to first 

 dorsal where median series ends, lateral series continue to end of 

 tail either side dorsal and caudal; spines gradually smaller towards 

 end of tail; all way from shoulder to first dorsal spines of lateral 

 series larger than median series ; also on sides of compressed tail from 

 root to nearly half way 2 belts of numerous, minute spines, belts 

 narrowing until at middle of tail continued as single row of small 

 spines to end of tail ; outer nasal edges with grooved, fringed, long, 

 j^rojecting funnel-like flaps and fringed flaps over mouth corners; 

 interorbital 1% in head to spiracle, flat. Spiracles slightly inclined 

 from horizontal, little less than eye and close behind. 



Except smooth areas behind spiracles either side and either side 

 median line above abdomen disk sparsely covered with stellate based 

 spines; latter as 2 broad belts on front disk edges, rostrum, inter- 

 orbital and orbital ridges, as triangular cluster behind head including 

 region of shoulder girdle; on hind disk edges each side group of
