Hydrobia (Paludestrina) jenkinsi at Lewes.— 



Referring to Mr. Lionel E. Adams' paper upon my recent dis- 

 covery of this species, it may be interesting to note that the 

 shell is increasing in numbers enormously. I visited the stream 

 a short time ago, and found the weeds covered with them ; a 

 gallon could be collected with a net in a very short space of 

 time. It is a most extraordinary thing that I have never found it 

 before this year, because I, as well as others in the town, have 

 worked the locality regularly for many years. If I had only 

 taken a few specimens I can understand that we might have 

 overlooked it, but how are such numbers to be accounted for ? 

 I have also recently discovered it in a ditch close to the river, 

 quite disconnected from the previous locality ; this place, how- 

 ever, I had never worked before, therefore I was not so much 

 surprised at finding it. — C. H. Morris, Lewes, i8th July, 18(^4. 



Hydrobia jenkinsi Smith. — Whilst journeying to Willen- 

 hall by Midland Railway, as I passed Short Heath Station I 

 noticed that one of the locks of the canal was dry, owing to some 

 repairs being done. I thought this would give me a good oppor- 

 tunity for examining the bed ; so after lunch I went to it, and 

 found a great quantity of Hydrobia jenkinsi, together with Unio 

 tumidus, U. pidorum, Afiodonta cygnea, a few Paludina vivi- 

 para, Bythinia tentaculata, and Limncza peregra. The bed 

 was literally covered with the Hybrobias ; you could scoop 

 them up by hundreds, and I found on reaching home that I 

 had close on 2,000 ! I should fancy they have been established 

 several years. — H. Overton, Brookdale, Tudor Hill, Sutton

Succinea oblonga in Jersey. — Mr. J. T. Marshall 

 informs me that he was fortunate in finding this species in 

 Jersey, last summer, five specimens being obtained. — J. W. 

 Taylor.
