 than eye; rostrum arched, projecting beyond jaws for a distance 

 equal to two-thirds diameter of eye; tentacular cavity large, as wide 

 as eye, illicium protractile, ending in two large globular lobes and a 

 narrow bifurcate structure; rostral spine moderate, pointing obliquely

 capped with a long slender spine ; scattered among the larger tuber- 

 cles are smaller ones; the large tubercles on the sides of the disk 

 are capped with bifid or trifid spinules; ventral surface of disk naked 

 except for a few tubercles on area between base of pectorals and vent;
