From Stat. 260 there are two verj smal! specimens, and one nearly of full size; the 

 latter resembles th<- type from the Sahul Bank ven d<>sely; the arms are 70111111. long; tin- 

 cirri, which are composed of s 7 gments, are from 7'' mm. to 75 mm. long. 



rhe material from Stat. 294 consists of five very small specimens, and a few cirri from 

 larger exampli 



The keels on the elements of the IBr series and on the first two brachials are considerably 

 higher in this species than in ./. cristata.

The centrodorsal is columnar, 5.5 mm. in diameter at the base and 3 mm. in interradial 

 height; the cirrus sockets are arranged in ten columns of two each ; the columns of adjacent 

 radial areas are close together, separated by a slightly marked irregular rounded ridge which 

 in width is equal to from one half to one third the diameter of the adjacent sockets; the two 

 columns of each radial area are separated in the midradial line by a slightly concave bare 

 space equal in width to about one half the diameter of a cirrus socket; the dorsal pole is 

 slightly concave, and is marked by five large, though low and obscure, tubercles as in the 

 other species of the genus. 



The cirri are about X, 87 — 98, 70 mm. to 80 mm. long, moderately slender; the 

 longest proximal cirrus segments are about twice as long as broad. 



The ends o\ tin: basal rays are prominent as small tubercles in the angles of the calyx. 



lh'' radials have a prominent median dorsoventrally elongated tubercle; the IBr, and 

 the proximal third or half of the axillary bear a narrow low rounded median carination, on 

 the former highest distally, on the latter highest proximally, the highest points being usually 

 marked by a slight elêvation in the general surface; traces of this are seen on the first two 

 brachials. In some cases there is a tubercle toward the distal border of the IBr,. and a similar 

 tubercle toward the proximal border of tin; axillary. the latter with tuint traces of broad tubercles 

 anterior to and on rither side of it ; each of tin- first two brachials also bears a tubercle. 



The arms are 105 mm. long.
