A VARIETY CAUSED BY LOCALITY. 



(Unio pictoniin var. compressa.) 



In Jeffreys' '• Manual of Land and Freshwater Shells " will 

 be found a named variety (compressa) of Unio pictoniin. When 

 my father first found this singular form, he was of ojjinion it 

 micfht be caused by circumstances, and those circumstances were 

 a peculiar rush of the current ; and I thought if it were so, they 

 ought to be found at another locality six or seven miles from the 

 place were they were first met v,'ith, though on the same river, and 

 syre enough they were there. 



I will now describe the place, hoping that some of your 

 readers may find the same variety in similar situations. It is in 

 places where the river winds so sharply that they are called here 

 " horse shoe reaches," the current rushes rather strongly at the 

 last bend to the other side of the stream and forms an eddy next 

 the bank on the outside of the bend, and these shells are found 

 just inside and at the edge of the sharp current next to the eddy. 

 The extreme abnormal form is very singular, nearly as broad as an 

 Anodojita, caused no doubt by the current washing away the 

 softer particles of mud, and the shell having harder work to keep 

 itself partially buried in the bottom causes the unusual expansion.

Helix caperata var. ornata Picard. — I have much plea- 

 sure in noticing an entirely new locality for this pretty variety, the 

 ones Mr. Jeffreys gives being North and' South Wales, South 

 Devon and Cork. I however found several specimens on the 

 summit of Amberley Down, in Sussex, at a considerable elevation. 

 The lower part of the Down on the north side, by which I 

 ascended was well supplied with Helix Cartusiana and Helix 

 ericetornin, but Helix cape?-ata was hardly to be found, and the 

 var. ornata appeared to be confined to the very top. The soil is 

 chalk. — Theo. Godlee^ Walthamstow.
