Another with the anterior arms 50 mm. loiitj and the posterior arms 30 mm. long has 
the cirri V , one in each interradial ansfle; there are four imj^rooved and si.\ grooved arms. 
A small individual with arms 30 mm. long has V cirri. 
A still smaller one with arms only 15 mm. long has the cirri \'I11, arranged in two 
interradial pairs with three occurring individuallw 
There are fourteen specimens additional similar to the preceding, and two very small. 
Stat. 274; two large individuals with the arms moderately swollen. 
Stat. 2S2; the largest example has arms 60 mm. long and cirri II; four have arms 
45 mm. long and cirri HI, III, IV and \'III ; one has arms 30 mm. long and cirri \'I-. there 
are eighteen others. 
In another lot from the same station there are seventeen specimens with arms ranging 
trom 12 mm. to 40 mm. in length; most of them have V cirri, one in each interradial area; 
the smallest has \l cirri arranged in two interradial pairs with two occurring individually, one 
of the interradial angles being vacant. 
From Stat. 285 there are two small specimens. 
Stat. 299; the largest specimen has arms 45 mm. long and cirri \'; three others have 
arms 40 mm. long and cirri III, V and \'I1I: another has the arms 35 mm. long and the 
cirri Y ; there are nine others. 
A small example from the reef at Stat. 301 has the arms about 40 mm. long and the 
cirri IX, two being very small. 
The largest individual from the reef at Haingsisi (Stat. 303) has the anterior arms 
85 mm. long and the posterior 50 mm. long; the cirri are II, but there are sockets for four 
more; another has the anterior arms 80 mm. long and the posterior 45 mm. long; the cirri 
are III: the two additional specimens are small." 
The larger specimen from .Stat. 318 has eleven arms 125 mm. long; the arms are of 
the slender type and , except for the arrangement of the cirri , the animal bears a close 
resemblance to that upon which Lutken based the name affinis\ the cirri are \'I, four in two 
interradial pairs and two occurring singly. The smaller example has ten arms 85 mm. long; 
the cirri are VIII, two occurring singly, the remainder in three interradial pairs.

This species exactly resembles the slender armed form of C. (C.) purpurea excej^t for 
the longer and more slender cirri. 
In the largest specimen, which has the anterior arms 125 mm. long (the posterior arms 
are broken), the cirri are IX, 14 — 15, 13 'mm. to 15 mm. long; they are arranged in four 
interradial pairs, with one occurring singly; the first .segment is short, the second nearly as long 
as broad, the third from one third to one half again as long as broad, the fourth and fifth 
twice as long as the median diameter; the following segments gradually become slightly shorter 
so that the third before the antepenultimate is about one third longer than broad, the next
