tributors and editors should be content with some of the worst in 

 the world. From the type in the British Museum I now offer an- 

 other illustration of L. crassilirata. It is larger and has heavier 

 spirals than L. armillata Sowerby* from the same region.

In the British Museum there is a single specimen labelled 

 "sirius Gould, N. Holland, M.C." This I identified as a juvenile 

 example of Astralium tentoriforme Jonas, which has priority.

I found in the British Museum a series of fourteen specimens 

 labelled "paludinella Rve., V.D. Land." Though the actual speci- 

 men figured by Reeve is not among them, this series is approved 

 as authentic by Mr. E. A. Smith. By comparison with specimens 

 determined for me by Mr. W. F. Petterd, Reeve's species proves to 

 be the Tasmanian fluviatile shell subsequently described by the Rev. 

 J. E. Tenison-Woods, as Ampullaria tasmanica. 



It follows that the record byPritchard and Gatlifff of L. paludi- 

 nella as a marine shell from several localities on the Victorian 

 coast, is erroneous, being, I think, based on the young of Melaraphe 

 praetermissa May. By Tate and May (antea xxvi., p. 388) it was 

 unfortunately included in the synonymy of M. mauritiana.
