JAPAÎS'ESE ASTEROIDEA. G5l 



bear as many as 25 spines, while the smaller i)lates may bear 

 any number less than that down to two or three. 



Maclreporite. — The madreporite is tolerably large but not very 

 conspicuous, owing to the presence of some prominent plates 

 around it, whose spines tend to overhang the margin of the 

 madreporic plate. It is more or less elliptical in outline and is 

 covered with short, irregular, discontinuous small furrows. 



Terminal plaies. — The terminal plates are relatively large but 

 not conspicuous in undenuded specimens, owing to its being 

 covered over with rough gi'anules. 



Locality. — All my specimens are from the southern parts of 

 Kyûshû and the adjacent islands. This species appears to be the 

 southern representative of Asterina batheri, but the distributional 

 limits of the two species can not be determined with the data at 

 hand. The exact localities of mv specimens are civen above.

In the Challenger Report, Sladex ['89, p. 303] mentions 

 Asterina penicillaris from Kobe ; but as there was a grave doubt 

 in my mind as to the occurrence of tliis species in Japanese 

 waters I asked my friend. Dr. F. A. Bather of the Natural 

 History Department of the British ]\Iuseum to examine the 

 original specimens of the Challenger collection, and he was so kind 

 as to furnish me with i\\Q following notes, dated April 3, 1905.
