sent on four rays, five 4 (3 + 4), one 2; one IIIBr 2 series is 
present, developed internally. 
This specimen agrees well with Carpenter's original description, 
and with his figure in the ""Challenger” report on the ""Comatulæ” 
(pl. XLIX, figs. 1, 2); it is flesh coloured, the arms crossed by 
purple bands. 
Another specimen has the cirri XIX, 32—35, 23 mm. long, 
and twelve arms 80 mm. long, two IIBr 4 (3 + 4) series being 
developed on adjacent rays. The colour is dark brown. 
April 16, 1907. Two typical specimens; one has fifteen 
arms 80 mm. long, one IIBr series being developed on each ray, 
one of them 2, the remainder 4 (3 + 4); the cirri are XVIII, 28 
—30, 20 mm. long; the other is of exactly the same size with 
sixteen arms, all the II Br series being 4 (3 — 4), and cirri XVIII, 
30—35; both are flesh coloured.

Singapore. November 27, 1907. The type. 
This species is nearest to 4. variipinna; but it appears to 
differ in its cirri, which are more slender, especially distally, with 
rudimentary dorsal spines and longer terminal joints, the total 
number of the joints being less; in its lower pinnules, which are 
not nearly so much enlarged, with less produced distal edges; and 
in its general build, which is considerably more slender. The ge- 
neral ruggedness so characteristic of variipinna is quite absent in 
this species, and the overlapping of the brachials is much less 
marked.
