PART 5 A MONOGRAPH OF THE EXISTING CRINOIDS 89 



specimen is small with arms only about 20 mm. long, but has XL cirri and P3 is as long 

 as P2 and slightly longer than Pj, which has only 10 segments. In my opinion this 

 specimen is more likel}^ to be a young Iridometra maxima.

History. — During a visit to the Museum of Comparative Zoology in the summer 

 of 1907 Dr. H. L. Clark showed me the crinoids which had been collected by the Alba- 

 tross in southern Japan in 1900 and subsequently turned over to him for study. He 

 had already gone over them more or less in detail and had made preliminary deter- 

 minations of the species; but finding that I was engaged in work upon the very much 

 larger collection which I had personally brought together in 1906 he most generously 

 handed over to me aU the material which had been sent to him, together with his notes. 



Among the new species he had distinguished was this form which I had not found 

 in the 1906 collection. I immediately wrote a description of it which was published 

 on October 29 of the same year. 



During the coinse of the PhiUppine investigations the Albatross dredged in 1908 

 near Hong Kong several specimens of a form which was evidently close to /. adrestine, 

 but which appeared to differ from it. This I described in 1911 under the name of 

 /. melpomene.
