radials visible, but short; slightly divergent distally; I Br^ trape- 

 zoidal, decreasing slightly in diameter anteriorly, proximally about 

 two and one-half times as broad as long; I Br, (axillary) broadly 

 pentagonal, about twice as broad as long, the lateral edges about as 

 long as those of the I Br^ ; II Br 2 ; III Br 2 ; IV Br 2, only found 

 on the outer side of the I Br series; all the joints to and including 

 the second brachial with prominent lateral processes, the outer edges 

 of which form a line parallel to the axis of the division series. 



Thirty-five arms (in the type) 85 mm. long, more slender than in 

 the other species of the genus; brachials as in C. unicornis, but pro- 

 portionately slightly longer. 



The pinnules are in general like those of C. unicornis, but P., is 

 much more slender, mm. long, with sixteen or seventeen joints, the 

 first nearly twice as long as broad, becoming squarish on the third, 

 and then gradually becoming about one-third longer than broad; 

 from the fourth onward the distal dorsal edge of the joints is strongly 

 produced, standing out in the form of a coarsely spinous crescentic 

 ridge. 



Color. — Deep violet, the cirri, P., and the dorsal side of the other 

 pinnules, bright yellow.
