The centrodorsal is thick-discoidal, the broad dorsal pole slightly concave, 9 mm. in 

 diameter Ihe cirri are XXVII, 33—35, 35 mm. to 45 mm. long. The diameter of the animal 

 at the leve! of the third brachial is about 27 mm. The colour is violet, with large blotches 

 of light yellow. 



This specimen agrees with others at hand from Australia.

a 1 Dorsal processes on the outer cirrus segments triple, consisting of a median 



carination with a dorsolateral keel on either side of it; usually about 40 arms 



b 1 cirri XV, 51 — 36, rather slender, about 25 mm. long (one third of the arm 



length): dorsolateral processes much lower than the median keel, developed 



only toward the tip of the cirrus ; division series with everted borders, and 



cirrus segments and brachials with produced distal edges, giving the animal 



a very rough aspect (Lesser Sunda Islands) sibogae 



b s cirri XVII — XIX, 39 — 50, very stout, 35 mm. to 45 mm. (usually about 

 40 mm.) long; dorsolateral processes but little shorter and lower than the
