rhe general structure of this species resembles that of A. propinqua y but the cirri are 

 proportionately larger, longer and more robust, 60 mm. to 65 mm. long with 63 — 64 segments, 

 and the ossicles of the IBr series and lower brachials are almost smooth, as in . /. vera. It 

 differs markedly from both of these in having the distal angles of the IBr, and the proximal 

 angles of the axillaries, and the corresponding angles of the first two brachials anti of the 

 elements "t" the first syzygial pair. widely cut awav, torming large and prominent rhombic water 



I he of the ossicles bordering these water pores are more or less everted and 



coarsely denticulate, or bear a few coarse spines.

'1 he dorsal pole of the centrodorsal is more blunted than in Carpenter's specimens, 

 and is studded with numerous small low tubercles. The cirrus sockets are in ten columns which 

 interradially in apposition, but well separated in the midradial line: there is usually only a 

 single functional socket to a column; the more distal obsolete cirrus sockets develop conical 

 .tubercles ol which the axes are parallel to the dorsoventral axis of the animal : these tubercles 

 are proportionate to ti of the cirrus socket which they occupy; thus below the functional 



socket in the columns there is a doublé row in each radial area of tubercles of diminishing 

 si/c which continues to the dorsal pole, there merging with the small polar tubercles. 



rhere are three cirri remaining contain 45 (om and 6] two) segments; in the first 



the transition segment is the ninth, in the two others the ei^hth. The cirri decrease slightly 



in diameter to the transition segment, and in lateral view increase in diameter on the short distal 



lents. The Iongest cirrus segment (the transition segment) is about twice as long as broad. 



The radials are visible as short and broad. more or less irregular, tubercles between 



the centrodorsal and the ll>r,; one or two tubercles springing from them are visible in the
