SUTHERLAND AND CAITHNESS FIELD-NOTES. 



By WILLIAM BAILLIE, 



Teacher, Brora, Sutherlandshire. 



I had some shell hunting in the summer and autumn of 1881 

 over several parts of Sutherland and Caithness. H. arbicstorum is 

 quite common on the east coast of Sutherland, often in company 

 with II. hortensis and H. hybrida. The ordinary form most 

 common, the greenish-yellow and dark brown varieties, are found 

 in Assynt, S.W. of Sutherland, at the foot of a high cliff about 600 

 feet above sea level. I also found a few specimens on the east 

 coast of Caithness near Dunheath Castle and at Brawl Castle on 

 Thurso River, N.E. Caithness. H. aculeata, found high up 

 Dunheath River, Caithness, H. ericetormn, found in one locality 

 on the north coast of Sutherland near mouth of Halladale River; 

 I have a colony of them on the east coast near Brora, but lost 

 sight of them during winter. II. rotundata, very common in east 

 Sutherland and Caithness. H. piilchella, common on the oolite 

 near the sea in E. Sutherland. Vitrina pellucida.^ very common 

 in Sutherland and Caithness. Zonites cellarius, allmrius, mtidulus, 

 purus, crystallinus dindfulvusm a few localities. Pupa ■umbilicata 

 occurs all over Sutherland and Caithness. Balia perversa, a few 

 found on a beech tree near Dunrobin Castle (Duke of Sutherland's). 

 Clausilia rugosa is found in considerable abundance about a 

 ruinous castle on Loch Assynt, S.W. of Sutherland ; last summer I 

 took a colony of them to the east coast, several greenish-white in 

 colour; it has also been found by others about Dunrobin Woods. 

 Cochlicopa lubrica is very abundant near the east coast, also at 

 Brawl Castle, Caithness; some are of a glassy appearance and a 

 few have a white band. Carychium mminium is abundant in a 

 few damp spots on the east coast oolite, particularly among rushes
