Rissoina varicifera, Tenison-Woods. 



From one of Johnstorx's lot, so named, and probably 

 co-types. Thisi agreesi fairly with the description, except 

 for the complete absence of varices on any of the speci- 

 mens. The author remarks, "the varices are not always 

 visible," but I doubt if this species would ever have true 

 varicesi. It isi a member of thei genus Estea and not far 

 from E. tasmanica, T'enison-Woods {Eulima). (Plat© XI.. 

 fig. 19). 



RUzoina johnstoni, Tenision- Woods. 



Fromi ai co-type. This common species appears to be 

 unfigured. It has long been recognised that the author's 

 generic location was at fault, and that the species is a 

 form of Bittium. (Plate XI., fig. 20). 



Pyramidella 'polita, Johnston. 



From the type. The specimen is only labelled 

 "Pyramidella," but I think there can be no doubt as to 

 its identity. It coimes near Syrnola infrasulcata, Tate, 

 but is smaller, narrower, and lacks the basal sulci. (Plat© 

 XL, fig. 21). 



Pyramidella sulcata, Johnston. 



Specimens labelled "Pyramidella," which agree well 

 with the description, show it to be only the juvenile state 

 of his Ringicula lactea, which has precedence. 



Pyramidella roherti, Tenison-Woodsi. 



Johnston's specimen, probably the type, shows this to 

 be a Turritella. The shell is small, and smooth, and prob- 

 ably in a juvenile state. I advise that it be abandoned 

 as too uncertain. 



Pileopsis navicelloides, Johnston. 



The type is crushed to powder. I consider the species 

 unrecognisable, and advise its abandonment. 



Gucullea, minuta, Johnston. 



Type crushed; probably a young shell. I advise its 

 abandonment also.
