thai the seventh and following arc about as long as broad; the fourth ami fullowing bear 
small subterminal dorsal tubercles, and also have the distal edge everted and prominent so 
that in a lateral view they appear to bear dorsally a broad tubercle with a concave crest. 
The 37 arms are 85 mm. long; on(; of the IIBr series is 2, the remaining nine being 
4 (3 + 4); the lIIHr series are all 2 ; the three which are absent are all external. 
The mouth is central, the anal tube submarginal.

The specimen from Stat. 274 is young; it possesses 27 arms 55 mm. long and cirri 
XIII, 10 — II, 8 mm. long. It appears to belong to this species and not to C. distmcta for 
the reason that the IIIBr series are developed externally as well as internally, both occurring 
on the .same IIBr series; in C. distincta external IIIBr series are very exceptional. 
The largest individual from Stal.- 294 has 41 arms 100 mm. long; the cirri are XXIV, 
II — 13 (usually 12) 10 mm. long. Of the others, which are very small, one has 11 arms and 
two 10 arms only. 
The largest example from Banda has about 36 arms which are about 75 mm. long; 
the cirri are q mm. long and are composed of 9 — 10 segments. Of the remainder one has 11 
arms 25 mm. long, one 10 arms 45 mm. long, and the last 10 arms 35 mm. long.
