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 XXIY, 

 44 — 47 (usually 46 — 47), 45 mm. to 50 mm. long; the cirri are rather stout basally, but taper 

 very appreciably distally; rather prominent dorsal spines are developecl from the thirteenth or

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

 are subequal, the longest (in the proximal portion) being slightly broader than long; the ends 

 of the cirrus segments in the earlier part of the cirri are slightly swollen and prominent. Another
