ON A COLLECTION OF CRINOIDS OF THE GENUS EUDIO- 

 CRINUS FROM JAPAN, WITH DESCRIPTION OF A NEW 

 SPECIES. 



B3" Austin H. Clark, 



Of till' United States Bureau of Fiftheries. 



The collections brought back by the United States Fisheries steamer 

 AJhatross from Japan contained, among many other interesting forms, 

 320 comatulids belonging- to the genus Eudiocrinus, which, with three 

 others in the United States National Museum, also obtained in Japan, 

 form the basis of the present paper, 



EudiocrinuH was found in abundance along the entire southern shore 

 of Japan, from southern Kiusiu and the Linschoten Islands to the 

 Gulf of Tokio, in water varying from 103 to T12 fathoms, with a bot- 

 tom temperature of from 37.5^ to 56.0° F. Only two species are rep- 

 resented in the 1906 collection, but the specimens in the National 

 Museum taken in 1896 prove to belong to a third species which we did 

 not meet with.
