PENTAMETROCRINUS TUBERCULATUS (A. H. Clark). 



1. Japan; Dr. F. Hilgendorf; Cat. No. 2831. — Two specimens, 

 badly broken. 



One of these resembles the type of the species; the other is smaller 

 and less tubercular. The cirri are all detached; the longest, which 

 presumably came from the larger specimen, are from 18 to 22 mm. in 

 length and are composed of from 16-17 segments. 



This species is easily recognized by its short cirri which have 

 comparatively few segments, and by the strongly curved terminal 

 claw. 



Carpenter, in the Challenger report, tentatively referred these 

 specimens to P. japonicus, evidently overlooking the very charac- 

 teristic detached cirri.
