46 PROCEEDINGS OE THE MALACOLOGICAL SOCIETY. 



Mr. B. B. Woodward exhibited, on behalf of the Rev. Canon Merle 

 Norman, specimens collected by Mr. Pickering in the Thames some 

 fifty years ago and labelled " Hydrohia castanea." Mr. "Woodward 

 pointed out that two of the specimens were referable to Paludestrina 

 ventrosa, Mont., and two to P. Je?ikinsi, Smith. The importance of 

 the exhibit lay in the fact that all doubt was now removed as to the 

 nature of the " Rissoa castanea, ? Jeff.," figured by Sowerby, to which 

 allusion had lately been made in the Society's Proceedings (vol. iii, 

 pp. 298-9). 



Mr. E. A. Smith exhibited the shell of a large specimen of Pleuro- 

 tomaria Beyrichii, Hilgend., from Japan, and Mr. M. F. Woodward 

 exhibited the animal taken from the same shell, drawing attention 

 to the very small, multispiral, homy operculum and other features 

 of interest. 



Specimens and drawings in illustration of their papers were placed 

 upon the table by the respective authors.
