"•inal neailv to tip of ray, decreasing in size distally. These paxillse usually stand 

 in the interval between two inferomarginals and are therefore widely separated. 

 Near the base of ray, however, the plates are closer and there may also be one 

 opposite the inferomarginal, although sometimes it lacks a paxillar develepment. 

 In the interradial region the plates touch one another. 



Madreporic body convex, situated about midway between center and margin. 



Color in life, salmon pink, tip of arms yellowish white.

The Alaskan examples are not quite t>'pical, tending slightly toward mxator 

 in having less widely spaced adambulacrals, slightly compressed inferomarginal 

 paxillffi and not quite so high or so delicate paxillse. Some examples recorded under 

 vexator from station 3331 stand nearly midway between the extremes, though nearer 

 vexator in the structure of abactinal and marginal paxillse, and spinelets. Possibly 

 the intermediate depths at which these were taken may in a measure account for 

 the less extreme development of the characters which make fur cilliger. 



The type from deep water has the distinctive characters of the species most 

 pronounced; the long rays, long paxillte pedicels and their crown of delicate glassy 

 furcate spiculiform spinelets usually radiating to form beautiful tufts resembling 

 miniature composite flowers; very prominent marginal paxillse, small actinal 

 interradial areas with few plates, and long delicate furrow spinelets.
