Another with the anterior arms 50 mm. long and the postenor arms 30 mm. long has 

 the cirri V, one in each interradial angle; there are four ungrooved and six 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 VIII, arranged in two 

 interradial pairs with three occurring individually. 



There are fourteen specimens additional similar to the preceding, and two very small. 



Stat. 274; two large individuals with the arms moderately swollen. 



Stat. 282; the largest example has arms 60 mm. long and cirri II; four have arms 

 45 mm. long and cirri III, III, IV and VIII; one has arms 30 mm. long and cirri VI; there 

 are eighteen others. 



In another lot from the same station there are seventeen specimens with arms ranging 

 from 12 mm. to 40 mm. in length; most of them have V cirri, one in each interradial area ; 

 the smallest has VI cirri arranged in two interradial pairs with two occurring individually, one 

 of the interradial anodes beingf vacant. 



From Stat. 285 there are two small specimens. 



Stat. 299; the largest specimen has arms 45 mm. long and cirri V; three others have 

 arms 40 mm. long and cirri III, V and VIII; another has the arms 35 mm. long and the 

 cirri V; 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 Lütken. based the name affinis\ the cirri are VI, 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.) pitrpurca except for 

 the lon^er and more slender cirri. 



o 



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 iifth 

 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
