Stat. 164. i°42'.5 S., I30°47,5E. 32 Metres. 2 Ex. 
The largest specimen from Stat. 33 has the arms 135 mm. long; the centrodorsal is 
thick discoidal, with the dorsal pole broad and convex, 7 mm. in diameter; the cirri are XXI\', 
44 — 47 (usually 46 — 47), 45 mm. to 50 mm. long; the cirri are rather stout basally, but taper

disk is almost completely covered with a pavement of rather small plates; the ^cirrus segments
