Helix nemoralis with formula 12045. — ^^^^ form Qi Helix iieiiioralis in which 

 the third band alone is missing seems to be generally regarded by conchologists as 

 scarce, so it may be worth while recording the capture of a well-marked specimen 

 with that band formula, 12045, '^his spring. It was taken from a fairly large colony 

 in a hedge-bank at Chingford, Essex, early in May. Additional specimens have 

 since been searched for without success. — F. B. Jennings {Read before the Sor.iety,

Paludestrina jenkinsi in Merionethshire. — Having a short time to wait one 

 day at Barmouth Junction, I spent the interval fishing in the surrounding ditches. 

 The result was Planorbis spiroibis, a few Pisidia, and one specimen of Paludestrina 

 ienkinsi. The last-named appears to be a new record for this part of Wales. Fresh- 

 water shells are strikingly few on this coast. Planorbis spirorbis, Linimza pereger 

 and L. irimcaiula are found sparingly ; other species of Planorbis and Limncea 

 seem to be entirely absent. — ^J. E. Cooper {Read before the Society, Sept. 14, 1910). 



Pseudanodonta elongata Hoi. in the Thames. — Mr. Fritz Haas has re- 

 corded (Proc. Mai. Soc, June, 1910) the occurrence of P. elongata Hoi. in the 

 Thames. It seems remarkable that this shell should have escaped notice so long. 

 So far as I can learn, the only valid external difference between Pseudanodonta 

 elongata and small specimens of Anodonta cygnaa lies in the beak sculpture. In 

 Anodonta this consists of a series of concentric ridges, while in Pseudanodonta it is 

 irregularly nodulous. I have taken one living specimen of what I suppose to be 

 Pseudanodonta elongata at Long Ditton, and several dead shells at Molesey. A few 

 of these are sent for exhibition and criticism. — J. E. Cooper {Read before the 

 Society, Nov. 9th, 19 10).
