From time to time several specimens of this exquisite species 

 have been obtained by Kuma iu the Sagami Sea, thongh mostly 

 in fragments. The exact localities are as follows : 



Gokeba, about ")72 m. (400 Ai;'« = 313 fras.). 

 Okiuose, about; 358 m. (2-10 hiro = 12Q fms.). 

 Outside Okinose, over oOO m. (3'30 ]t.iro = 21-i fm?.). 

 Inside Okinose by Ena-line, between 429 and r)72 m. 



(3-400 /iH-o = 235-3 13 fms.). 

 Ike-line''' by INIochiyama-line, about 832 m. (580 hiro = 

 454 fms.). 



Many of the specimens bear at the base a sample of the 

 bottom, invariably a tufaceous rock, to which they are firmly 

 attached. 



If I am right in regarding i?. decora F. E. iScn. as identical 

 with li. okinoseana, a very wide distribution is to be ascribed to 

 the species. Schulze's type of 7?. decora came from a spot in 

 the Indian Ocean, SAV. of Cape Comorin and 787 m. deep. 



Attached to the skeletal stumps of dead specimens from 

 Okinose Inside, I have found an interesting series of the young,
