 in the outer part of the pinnule being twice as long as broad; the dorsal portion of 

 the distal edge of the fourth or fifth and following segments is produced and spmous. 

 P, is 4.5 mm. long, very delicate, with 14 segments which distally become twice as 

 long as broad. Prmay resemble P2, or it may be shorter though of the same character ; 

 the following pinnules are short, but stiffened. The long proximal pinnules are re- 

 curved distally.

 Japan [A. H. Clark, 1913] (2, B. M.). 



Geographical range. — Southern Japan from the Goto Islands eastward to Sagami 

 Bay. 



Bathymetrical range. — -From shallow water down to 137 meters. 

 History. — This species was first described as Antedon tigrina by me from 19 

 specijnens labeled, with a query, Kagoshima Bay that had been collected by the 

 United States North Pacific Exploring Expedition under Capt. John Rodgers in 

 1852-1855. In a footnote appended to the original description I said that since the 

 description was put in type I had examined several other specimens of the species 

 taken in Sagami Bay in 1900, so I had no doubt the original specimens did come from 

 Japan. These specimens from Sagami Bay were from the Albatross collections, and 

 they were shown to me by Dr. Hubert Lyman Clark at the Museum of Comparative 

 Zoology at Cambridge, Mass. The collection of crinoids made by the Albatross on 

 the coasts of southern Japan in 1900 had been turned over to Dr. Clark for study, and 

 he had brought them with him from Oberlin to the Museum of Comparative Zoology. 

 On learning that I was engaged in studying the much larger collection made in southern 

 Japan by the Albatross in 1906, Dr. Clark, with his characteristic courtesy and gen- 

 erosity, turned over to me all the crinoids in his custody.
