Diagnostic features. — The cirri are long, stout basally and gradually tapering to 

 a sharp point distally, nearly straight or slightly curved, composed of 40-60 segments 

 of which the distal are much longer than broad and are entirely smooth dorsally; 

 there is no opposing spine and the terminal claw is nearly straight. 



Description oj a specimen labeled Sydney, N. S. W. — The centrodorsal is large, 

 thick discoidal, with a broad flat polar area 5 mm. in diameter. The cirrus sockets 

 are arranged in a single marginal row. 



The cirri are XVI, 42-46, 45 mm. long, large and stout basally but gradually 

 tapering, rather more rapidly in the distal portion, to a very slender sharp pointed 

 tip. The first four or five segments are about two and one-half times as broad as 

 long, and those following gradually increase in length, becoming about as long as 

 broad at the tenth, then slightly longer than broad, and in the terminal 10 or 12 

 about twice as long as broad. The cirri are rounded dorsally with no dorsal spines 

 or carination. The terminal claw is long, about as long as the penultimate segment, 

 and nearly straight. 



The anterolateral corners of the radials are barely visible in the interradial angles 

 of the calyx. The IB^ are very short, six or eight times as broad as long, rather 

 Longer laterally than in the midradial line, almost entirely united laterally. The 

 IBrj are low triangular, about three times as broad as the median length, the lateral 

 borders about as long as those of the IBr,, well separated laterally. There are 6 

 IIBr series present, all 4(3+4). Each IIBr series bears two IIIBr 2 series, there 



- in all 12 of these. One IIIBr series bears a IVBr series of 2 on the inner 

 side of the IIBr axillary and outer side of the following IIIBr axillary. The division 

 series are well separated, well rounded dorsally, the sides smooth without lateral 

 projections or carination. The ossicles immediately following each axillary are united 

 interiorly. 



The 29 arms are 130 mm. long. The first eight brachials are approximately oblong, 

 about three times as broad as long, those following becoming obliquely wedge-shaped,
