The specimen from King Island, Mergui Archipelago, was thus described by Dr. 

 P. H. Carpenter: 



The centrodorsal is a thick disk. 



The cirri are about XL, 60-70, reaching 60 mm. in length. The cirrus segments 

 are tolerably uniform, and those in the distal half of the cirri bear sharp dorsal spines. 



The radials are partially visible. The IBr, and IBrj (axillaries) are narrow and 

 strongly convex and are united by syzygy. The postradial series are quite free later- 

 ally and divide four or five times. Each division series consists of two articulated 

 ossicles of which the first is nearly square and the axillary is pentagonal, often as 

 long as or longer than broad. All the ossicles of the division series are relatively deep 

 and narrow, with a strongly rounded dorsal surface. 



The arms are very numerous, 15 or 18 to the ray (75-90 in number), 175 mm. in 

 length. The brachials are laterally compressed; the lower are oblong, and their suc- 

 cessors are more unequally quadrate. 



The first syzygy is between brachials 3 + 4, with others following at very uncer- 

 tain intervals of from 6 to 14 muscular articulations; but they are apparently alto- 

 gether absent from some arms. 



Pi is slender and tapering, consisting of 35 or more elongated segments and reach- 

 ing nearly 25 mm. in length. The next few brachials bear quite short pinnules with 

 only some 6 or 8 segments, and their successors increase slowly in length, but never 

 become specially long. 



The disk is 25 mm. in diameter and is much incised. It is not regularly plated, 

 though the integument is very dense and tough. Sacculi are very abimdant on the 

 pinnules. 



The color is very dark, almost black — probably deep purple in life — with lighter 

 patches on the arms. 



Carpenter's material from King Island consisted of one specimen and a detached 

 disk. 



The specimen from Padaw, Mergui Archipelago, is a broken example with about 

 85 arms.
