History. This species was originally described in 1908 from specimens collected 

 by the Albatross in the Philippines earlier in the same year. 



In 1922 Dr. Torsten Gisle"n recorded and gave notes upon eight specimens dredged 

 by Dr. Sixten Bock in the Bonin Islands and southwestern Japan and mentioned 

 incidentally that there were other specimens in Dr. Th. Mortensen's Japanese collec- 

 tion. He found that the specimens from the Bonin Islands and southern Japan 

 included in Bock's and Mortensen's collections differed from C. magnifica as originally 

 described in having fewer arms, shorter cirri, and very much shorter proximal pinnules. 

 He therefore proposed that they be recognized as representing a new variety, which 

 he called minor. As in many species of crinoids individuals from certain localities in 

 the Philippines and from some other localities in the East Indies are considerably 

 larger with more numerous arms than those from elsewhere, it does not seem advisable, 

 at least for the present, to recognize this new variety. 



In 1927 Gislen recorded and gave notes upon the six specimens in Mortensen's 

 collection from southern Japan, referring them to his new variety minor.
