small pits, the remnants of cirrus sockets, on its margin. The colour is yellowish white, the 
pinnules being- yellow green. 
Except for the smaller size and tiie slightly less developed centrodorsal this specimen 
agrees well with tiic tyjjc, with which it was directly compared.

One of the specimens from Stat. 318 is a magnificent example of the species ; it has 
I 10 arms 140 mm. long; no full\- developed cirri are preserved, but from the young cirri 
present it appears undoubtedly to be referable to this form instead of to C. sentosa which, 
except for the cirri, it exactly resembles. Th'e other two are smaller, with 33 and 3s arms 
and cirri 35 mm. long composed of 28 — 36 segments. They seem to belong to C. gracilicirra 
rather than to C. taiuicirra, though they have not as \et acquired all of the characters of 
that type. 
The single individual from Stat. 320 has been chosen as the type of the species; the 
cirri are X\'^II, 27 — 35 (usually nearer the latter), 33 mm. long; the longest proximal cirrus 
segments are twice as long as broad, slightly constricted centrally with swollen ends ; the 
shorter distal segments are about as long as broad ; the tenth or eleventh is a transition seg- 
ment ; the eleventh or twelfth has several sharp spines on the distal dorsal border: in the 
following two or three segments the central spine rapidly increases in size, becoming a long 
subterminal dorsal spine, flanked at the base by a smaller one on either side. The other cha- 
racters are as in C. sentosa. There are 51 arms 100 mm. long. 
The smaller specimens from Stat. 318 are peculiar in having on the outer cirrus seg- 
ments two dorsal spines, a proximal and a distal.
