B. Jiystrix is very closely allied to the present species, differing only 

 in having the dorsal perisome "rauh durch die hervortretenden 

 Nadeln der Kalkkorperchen," which are visible to naked eye. From 

 it and other allied species, B. lingua Perrier, B. janihina v. Maren- 

 zeller, and B. sordida Theel, my species differs above all in having 

 characteristic anchor-bearing spicules. The species is named for 

 Prof. Seitaro Goto of the Tokyo Imperial University.
