Operculum — 1 Long. 1|, diam. 1 mill. Hob. — In Australia. 

 Mus. Cuming. 



S. frustillum has, I believe, not been again collected, noted in 

 literature or illustrated. Since Cuming's localities are so dubious, 

 the species may not really be Australian. S. australis differs 

 from S. frustillum in size, the number of whorls, the proportion of 

 the last whorl, the sculpture and the colour. 



Daphnella tasmanica, T. Woods.

 (Fig. 21.) 

 The Rev. H. D. Atkinson has kindly lent me 

 a specimen, which, I understand, is one of the 

 original lot of this species. From it the accom- 

 panying figure was made. It seems probable to 

 me that Clathurella lamellosa, Sowerby,* was 

 based on the young of this. 



To this species Messrs. Pritchard and Gatliff 

 have united Many ilia jacksonensis, Angas f A 

 comparison of the descriptions of Woods and 

 Angas shows that such synonymy could only 

 rest on mistaken identification. 



Hydatina tasmanica, Beddome. 



Akera tasmanica, Beddome, Proc. R. Soc. 

 Tasmania, 1882, p 169. 



(Fig. 22.) 

 To the kindness of Miss M. Lodder I am 

 again indebted for the opportunity of 

 illustrating an unfigured species. Prof. 

 Tate, upon inspecting this drawing, pointed 

 out to me that the species would be better 

 referred to Hydatina.
