spine is very small, terminal; ihc terminal claw is slioluly longer than the penultimate segment, 
moderately slender, and moderately and evenly curved. 
The ends of the basal rays are just visible in the angles of the calyx, bridging over 
the narrow subradial clefts; the IHr, are very narrow, trapezoidal, about five times as broad 
as long-, entirely united laterally; the IBr^ (axillaries) are very broadly pentagonal, twice as 
broad as long, free laterally; ihr IlHr series are 4 (3 + 4). 
There are 20 arms i 10 mm. long; one of the \\V>v series is absent, but a lll>r 2 
series (the only llBr series not 4 [3 + 4]) bears a IIlBr 2 series internally; the brachials 
resemble those in \oimg specimens of C. micltiradiata ; the more jjroximal are obliquely wedge- 
shaped, almost triangular, half again to twice as broad as long; the distal edges of the bra- 
chials are slightly produced, and are armed with numerous .short fine spines. Syzygies occur 
between brachials 2 + 3, 13^-14 to 30 + 31 (usually in the vicinity of the 15"^), and distally 
at intervals' of from four to eight (usually seven) oblique muscular articulations. The dorsal 
and lateral surfaces of the arms and division series are thickly beset with very fine spines, 
which are rather more prominent on the lateral surfaces. 
Pn is 15 mm. long with 30 segments; the comb, which resembles that of C vnilii- 
radiata^ consi-sts of from seven to nine well developed, and three or four rudimentary teeth ; 
the pinnule is comparatively slender: Pj is 14 mm. long, similar to Pd , but slightly more 
slender; P., is 13 mm. long, similar to Pj ; P., is 10 mm. long, resembling the preceding; P^ 
is 8 mm. long, with a comb ; combs occur at intervals to the end of the proximal half of 
the arm. 
The mouth is submarginal, radial ; the anal tube is central ; the perisome of the disk 
is naked. 
Another specimen from .Stat. 166 has 14 arms 100 mm. long and cirri X\'I, 28 — 30, 
28 mm. long; on some of the cirri the outermost segments bear dor.sally a transverse ridge 
with a small but distinct spine in the centre; one of the IIBr series is 2, the remainder 4 
(3 + 4). 
Of the fourteen specimens from Stat. 318 one has 10 arms, two have 11, three 12, 
one 13, one 15, three 16, one 23, one 25, and one 30 ; the largest and best developed 
example has 25 arms 125 mm. long, and cirri 35 mm. to 40 mm. long; the arms borne by 
the five rays are 4, 4, 3, 3, 1 i ; the right posterior ray bears a I Br series ending in a tra- 
pezoidal ossicle from which four arms are given off, two, side by side, from its distal (longest) 
face, and one from each of the lateral faces: this segment represents two normal IIBr axil- 
laries (with their derivatives) fused, and there is a faintly indicated median dividing line. An- 
other large individual has 23 arms 125 mm. long; of the nine IIBr series one is 2, one i, 
and the others 4 (3 -f 4) ; individual IIIBr series are all internal. 
The specimen from Stat. 319 has 32 arms 85 mm. long: on every ray one of the 
derivatives from the IBr axillary remains undivided so that 27 of the arms are borne upon 
five IIBr series. 
Of the e.xamples from Stat. 320 two have 10 arms, two 12, two 13, two 14, one 17, 
one 18, two 21, two 22, one 23, and one 28; one with 21 arms has the anterior and right
