with 18 segments of which the fourth and following are longer than broad, those 

 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 spinous. 

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

 long as broad. P 3 may resemble P 2 , 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.

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

 specimens 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 Oberlm 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.
