2 28 PEACH : ON CAITHNESS MOLLUSCA. 



Clausilia rugosa. — In the cliffs on the sea coast, near Girnigo 

 Castle, Southend, Wick, and old Umekiln near Hemprigs. 



Cochlicopa lubrica. — In several places. 



So far the list for Caithness. I am, however, desirous of 



adding two shells found by me in Sutherlandshire, 



believing they are of sufficient interest to be noticed here. 



Helix rupestris.^ — On limestone rocks at Durness, in August, 

 1857. Rare. Fleming mentions it as a Scotch species. 



Bulimus acutus. — Sandhills at Auldshore Beg, near Cape 

 Wrath, Jul^, 1861, and at Durness, August, 1857, associa- 

 ted with Helix ericetorum. It is strange not to find it 

 with the above shell in Caithness. Dr. Gordon says [of 

 B. acutus] ' Collected in Caithness, and found in rather a 

 suspicious locality, on a mantelpiece, and had been pre- 

 sented to the Rev. J. Leslie, of Burghead.' 

 N.B. — Those marked with an asterisk (*) have also been 



found in the marls of Caithness. 



[The above seems hitherto to have been published in a 

 newspaper only, and we consequently think it desirable to re- 

 print the paper verbatim. — Ed.] 



Planorbis corneus v. albinos in Warwickshire. — 



This variety, which a few years ago was considered one of our 

 rarest shells, is apparently becoming of more frequent occur- 

 rence. Mr. Madison, of Birmingham, has recently found it at 

 King's Norton in Warwickshire. Some fourteen or fifteen years 

 ago a dealer in Aquaria in Birmingham had unknowingly a good 

 number of this variety mixed with the ordinary form amongst 

 his stock, all presumably obtained in the neighbourhood of 

 Birmingham. They were detected by Mr. Nelson, who 

 procured from him a good number of fine specimens. —
