Differs from H. stellata in the following particulars : — 



(1) the cephalic disk is circular and is decidedly elevated anteriorly, and 

 there are no cutaneous filaments along its edge, except at the chin : 



(2) the eyes are about ^ the length of the disk, and are rather more than a 

 diameter apart : 



(3) the caudal is - the total length (itself included) : 



(4) the ventrals, which are only about half the length of the pectorals, are 

 slender. 



Colours in life, blue-black with jet black vermicular lines on the dorsal 

 surface : in spirit bluish with the black lines more distinct. 



A single specimen, just over 2^ inches long, from the Andaman Sea, 188 to 



220 fathoms. 



Regd. No. 13027. 



It is quite possible that this is only a variety of H. stellata.

 Differs from H. stellata in the following particulars : — 



(1) the cephalic disk is circular and is distinctly elevated anteriorly, and the 

 cutaneous filaments on its edge are few and inconspicuous : 



(2) the spines of the dorsal surface have needle-like points, and the under 

 surface of the disk is well covered with stellate spines : [in the young the spines 

 of the under surface are scattered and very small] : 



(3) the interorbital space is but slightly concave and its width is much more 

 than a diameter of the eye : 



(4) the caudal is about a fifth the total length : 

 ■ (5) the ventrals are slender: 



(6) the parietal peritoneum and branchial mucosa are jet black and parti- 

 cularly thick. 



Colours in fife : " dorsum bright pink, with fine black vermicular lines ; 

 under surface crimson " : in spirit white, with the black lines very distinct and 

 the black peritoneum and branchial mucosa showing through on both sides of 

 the disk. 



Numerous specimens from the Andaman Sea, 265 and 185 fathoms : the 

 largest is just over 7 inches long.
