The ends of the basal rays are usually, but not always, visible as small tubercles 

 in the interradial angles. 



The distal edge of the radials is even with the rim of the centrodorsal and is 

 nearly straight so that the radials are not prominent interradially. The IBr, are 

 oblong, 3 or 4 times as broad as long, with produced lateral borders which are in 

 apposition with the smiilarly produced lateral borders of the neighbormg IBr,. The 

 IBra (axillaries) are low pentagonal, over twice as broad as long, produced laterally 

 into a thin edge which curves forward and encloses the outer side of the first brachial 

 in the form of a broad hooklike process which may reach as far as the second brachial, 

 or only halfway up the side of the first brachial; sometimes it is only slightly 

 developed. 



Arms 10-12 (usually 10, in 2 individuals 11 and in 1, 12), from 55 mm. to 60 mm. 

 long, resembling those of C. callista. 



P2, which is from half again to twice as long as P,, is 8 mm. long; from this point 

 the pumules very gradually decrease in length, then gradually increase to 9 nmi. 

 distally. 



Notes. — Of the 14 specimens examined 10 had 10 arms, 2 (from stations 4894 

 and 4936) had 11 arms, 1 (from station 4936) had 12 arms, and 1 (from station 4903) 

 had 15 arms.
