JAPANESE ASTEROIDEA. 173 



the more central ones are only shorter and blunter than the more 

 peripheral ones. In the smaller paxillaG found along the inner 

 margin of the superomarginals there are no centrals and the 

 coronal spinelets, of which there may be five or more, simply 

 diverge from the apex of the pedicel. 



Madveporite. — When exposed this is tolerably large. It is, 

 however, more frequently hidden from view for the greater part 

 by the surrounding paxillae ; but even when it is projecting, it is 

 not so conspicuous as in Astrop. scoparius, since the exposed 

 surface is covered with granules of irregular form (PI. Ill, fig. 50). 

 The margin is crenato, and the surface covered with irregularly 

 radiating furrows. It is nearer the margin than the centre of the 

 disk. 



Terminal plate. — This is quite conspicuous and bilobed at the 

 apex. 



Localitij. — My specimens are from the following localities : 

 Akune (Satsuma), Kagoshima Bay, Hososhima Bay (Hyuga), 

 Nagasaki, Kashiwa Island (off the coast of Tosa), Gogo Island 

 (ofi* the coast of lyo), Ohama (Wakasa, Japan Sea), Wakanoura 

 (Kishu), Tsu (Gulf of Isé), Enoura (Suruga), Misaki, Awa. 

 According to a note in my possession the ambulacral feet of this 

 species are red. The whole abactinal side of the body is of a 

 murky brownish colour. 



This species appears to live on sandy or muddy bottoms and 

 is found at greater depths than Astrop. scoparius. I have however 

 no definite data to fix its bathymetrical range. The records of 

 the Challenger are perhaps the fuUest on this point.
