the calyx, more or less obscured by the tubercles arising from the radials above them, and 

 the cirri beneath. 



The proximal border of the IBi'j is turned outward and more or less scalloped ; the 

 median third of this border is straight and parallel with the proximal border of the centrodorsal ; 

 the lateral thirds slant outward and upward, and are slightly concave; the edge of this eversion 

 is thickened and smooth; the lateral portions of the distal border of the IBr x are also everted, 

 but not nearly so prominently as the proximal border. The IBrj is very slightly longer than 

 in the "Challenger" specimens, and the distal border is not quite so inuch incised ; this 

 undoubtedly is due to the smaller size of these individuals. 



The axillaries are not quite twice as broa d as long i the proximal edge is slightly 

 straighter than in the "Challenger" specimens, and is slightly everted; the lateral borders of 

 the elements of the IBr series and of the first brachial and the inner borders of the first two 

 brachials are laterally produced. 



Pj is greatly enlarged with 12 or 13 segments of which the first eight or nine are 

 sharply flattened on the outside, the ventral border being somewhat produced ; the second and 

 third segments are strongly carinate on the inner ventral border, especially the third, but from 

 this point the carination rapidly diminishes in extent, disappearing three or four segments 

 further on ; on the second segment this carination is parallel to the dorsoventral plane. but it 

 gradually becomes recumbent so that on the fourth it is at right angles to this plane. 



The brachials bevond the tenth are triangular, about as long as broad, with very finely 

 spinous distal margins; the dorsal line of the arms is smooth in profile.

This species is closely related to A. propinqua-, the edges of the segments of the IBr 

 series and of thé earlier brachials are but very slightly-, if at all, everted, and are armed with 

 exceedingly fine spines or are quite smooth ; the spines within the distal angle of the axillary 

 and on the dorsal surface of the ossicles are exceedingly short and fine and difficult to detect. 



The larger has 10 arms , abeut 130 mm. long; the cirri are 60 mm. long and are 

 composed of 62 — 69 segments of which the longest are from third to one half again as long 

 as broad; the sixth or seventh is a transition segment.
