proximal part and aii uncalcified space in the distal part. Under 

 surface of zoariuni irregularly ridged. 



Locality. — Cape Otway (J. Denuant). 



This is a very distinct form. One specimen is oblong, with 

 the corners rounded, the other is oval ; the front wall of the 

 zooecia is nearly circular and somewhat resembles that of 8. 

 marginata, but the very peculiar vibracular cells separate it 

 from all other species. It has two openings, the proximal one 

 being auricular in shape, and probably that in which the vibra- 

 cula were articulated. It is also a very good exemplification of 

 the closing up process which takes place in some species ; each of 

 the specimens shows cells partially and entirely tilled up, and in 

 the small portion figured there are several partially, and one 

 entirely closed.
