Best in the N.Z. area, especially Stations 9, 10, and 11. At Station 10 a 

 double specimen with two apertures. The spines are most pronounced in the 

 deep-water Stations, reaching a maximum at Station 27 where, however, the 

 species was uncommon.

This species dift'ers from B. aculeata by being finely hispid all over the 



surface of the chambers instead of having the spines confined to their margins. 



It is very rare, but well marked specimens occur, the best at Station 11.
