One specimen. A very distinct white shell with moniliferus whorls 

 rising in stages. (Tenison-Woods}. 



I have not seen this species. It is evidently closely related to the 

 preceding.

Shell conical, very solid, annulate at the periphery, with a very 

 shallow umbilicus; white, variegate with maculations and radiating

 subcanaliculate sutures, the apical ones when not eroded spirally 

 striate, the following granose-lirate, the last bearing on its upper 

 surface five coarse beaded Iira3, the fifth forming the periphery ; 

 base slightly convex, bearing six beaded line ; interstices between the 

 lira? finely obliquely striate; aperture rounded-tetragonal, pearly 

 within ; outer lip lirate within ; basal lip curved, subdenticulate ;

A solid little species, allied to the preceding, but differing in 

 coloration etc. The specimens before me exceed the types in altitude. 

 A variety from Tasmania is of a uniform deep purple color, (pi. 14, 

 fig. 33.) It may be called var. PURPURATUS.

 of the umbilicus, orbicularly conoid or subdepressed, thick, solid ;
