K. OKTNOSEANA. 223 



REGADRELLA OKINOSEANA Ij. 



Pis. VII and VII r. 



B. oicinoseana, Ijima 'q6, p. 250. 



E. decora, F. E. Schulze ig', pp. 30-34, 43 ; pl. vi, 

 %s. 10-18. 



From time to time several specimens of this exquisite species 

 have been obtained by Kuma in the Sagami Sea, though mostly 

 in fragments. The exact localities are as follows : 



Gokeba, about 572 m. (400 ÄzVo = 313 fms.). 

 Okinose, about 358 m. (250 h{ro = 19Cj fms.). 

 Outside Okinose, over 500 m. (350 hi, '0 = 274: fms.). 

 Inside Okinose by Ena-line, between 429 and 572 m. 



(3-400 Airo = 235-313 fms.). 

 Ike-line"'"' by Mocliiyama-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 II. decora F. E. Sch. as identical 

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

 the species. Schulze's type of 7t. decora came from a spot in 

 the Indian Ocean, SW. 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, 



*Tlus line, not given in PI. XIV, lies a short distance to the east of the Jögashima Lt. 

 house line.
