size, the largest obtained measuring 4.^ by 3^ inches. Of SphiErluni, 

 only 5. corneuni (single valves) can be recorded, except one immature 

 specimen ; and Pisidium amnicuin was the sole representative of this 

 genus. 



The figures prefixed to the species refer to the numbers as found 

 in the Conchological Society's "List of British Non- Marine Mollusca," 

 published in 1904, and the nomenclature used is that of the same 

 list. Species not recorded in the last Census List are marked with 

 an asterisk (*) ; these have been submitted to the Society's Recorder, 

 Mr. Charles Oldham, to whom I am indebted for looking over the 

 specimens collected and rendering valuable assistance to me in com- 

 pleting the annexed list.
