IIIROSIII OIISHIMA : 



Three fragments. Nanao, Province Noto, Honshu. (Cat. no. 1 119). 



One specimen. Okinosé, inside, Sagami Sea, 300-400 hiro ( = ca. 

 240-310 fathoms). Aoki coll. March 7, 1895. (Cat. no. 1669). 



Three specimens. Koajiro, Misaki. (Cat. no. 1815), 



Several specimens. Koajiro, Misaki. Aug., 1887. (Cat. no. 1668). 



Two specimens. Koajiro (Shore), Misaki. July 17, 1890. (Cat. 

 no. 1 1 16). 



It may be worthy of note that this littoral species may occur at 

 a depth of 240-310 fathoms (no. 1669). This species has been reported 

 before from Miya Bay (v. Marcnzeller) and from the " Challenger " 

 Station 233 F>, off Sanuki, Inland Sea, 8-50 fathoms (Théel). 



In a former paper I made notice of spicules being of very differ- 

 ent sizes in radii and interadii. I now find in some specimens that 

 that arrangement is not quite distinctly carried out ; nevertheless the 

 anchors and anchor-plates are largest in the middle part of interradii 

 and decrease in size towards radii. Anchors range 170-545 fi and 

 anchor-plates 140-430 fi in length. Large anchors in interradii show 

 on each arm ten or more minute teeth.
