l>,,itjnosticjeatures. — The cirri are large and stout, more or less straight proximally, 

 curved distally, with the longest proximal segments varying from nearly twice as 

 broad as long to nearly as long as broad; the cirri are 30-50 mm. long, with 35-47 

 segments, the earlier sometimes with a broad transverse ridge or paired spines; the 

 arms are 130-300 mm. long, usually 10, occasionally 11 or 12. 



Description. — The centrodorsal is thick discoidal, more rarely more or less hemi- 

 Bpherical, 6 8 mm. in diameter at the base; the bare dorsal pole is usually broad, 

 about 3 nun. in diameter, and is usually more or less convex, less commonly flat, and 

 sometimes with a small median pit. The outer margin of the dorsal pole is more or 

 less swollen at the bases of the adjacent cirri. The cirrus sockets are arranged in 

 usually two closely crowded alternating rows. 



The cirri are XVII-XLIII (usually XX-XXX), 26-47 (usually 35-40), in fully 

 -.Town individuals 30-50 (usually 35^0) mm. long. The cirri are large and stout, 

 becoming laterally compressed distally. They are commonly stout basally, tapering 

 \ i [ \ appreciably distally; but they may be, m lateral view, of uniform width through- 

 out, or broader in the compressed distal portion than proximally, the last two types 

 being aometimes found in the same individual. The first segment is very short, up 

 to twice as broad as long or even broader, those following gradually increasing in 

 length to the -i\th to ninth, which, with a few of those following, are from twice as 

 broad as long to nearly as lung as broad, most commonly about half again as broad as 

 long. The segments following arc shorter. The longer earlier segments have slightly
