 Obs. — Except for the pullus, this species is of the V . sarissa type, 

 which is evidently its analogue in the Muddy Creek Beds, Victoria, 

 so far as general habit is concerned, but its greater proportional 

 length of body whorl to spire is a very distinctive feature, which 

 may at once be seized upon. V . pueblensis, Pritchard, from Spring 

 Creek, i« another very close ally, and may, in fact, ultimately prove 

 but a variation of this species, when a good series can be obtained, 

 but at present the larger pullus, the more slender habit, and the 

 delicate costation serve to distinguish the Victorian form. In a 

 recent letter from Mr. R. N. Atkinson he mentions a volute of the 

 tateana-saris.' ' pe, a mature shell smaller and much more elongate 

 than V. tateana amongst his discoveries. It is not unlikely that 

 this may compare favourably with V . pueblensis. or help to bridge 

 the gap between that species and V. tateana. Specimens of V . 

 tateana are on view in the Hobart Museum, but the type is not 

 amongst them. Tate only records the species from Table Cape on 

 the authority of Johnston, so it is to be presumed that the ty2:>e is 

 in Mr. Johnston's collection.
