The specimen from Stat. 286 is slightly smaller and more slender than the preceding, 
with the spinosity of the IBr series and first two brachials very slightly finer and thicker. The 
arms are 80 mm. long; the cirri are 27 mm. long with 44 — 51 segments.

I am now convinced that the specimen from the Andaman Islands in about 485 fathoms 
of water which I recorded as Thalassometra pergracilis does not in reality represent that 
species. It is in too poor condition for de'finite determination.
