From Stat. 260 there are two very small specimens, and one nearly of full size; the 
latter resembles the type from the Sahul Bank very closely; the arms are 70 mm. long; the 
cirri, which are composed of Sy — 89 segments, are from 70 mm. to 75 mm. long. 
The material from Stat. 294 consists of five very small specimens, and a few cirri from 
larger examples. 
The keels on the elements of the I Br .series and on the first two brachials are considerably 
higher in this species than in A. cristata.

I Ex. 
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 of the basal rays are prominent as small tubercles in the angles of the calyx. 
The radials have a prominent median dorsoventrally elongated tubercle; the IBrj and 
the pro.ximal third or half of the a.xillary 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 elevation 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 IBrj, and a similar 
tubercle toward the proximal border of the axillary, the latter with faint traces of broad tubercles 
anterior to and on either side of it ; each of the first two brachials also bears a tubercle. 
The arms are 105 mm. long.
