LAND AND FRESHWATER MOLLUSCA OF SCOTLAND 167 



company with a few examples of V. edentula. We have 

 had the opportunity o{ examining the specimens of both, V. 

 substriata being especially noteworthy as an addition to the 

 South Perthshire list. 



19. Shells in North Perthshire. — Mrs. Carphin 

 sent us single examples of Helix granulata ( = sericed), H. 

 arbustorum, and Unio viargaritifera, from Dunkeld, and all 

 of them additional records for the vice-county, for which we 

 have now had 52 species placed on record. 



20. The White Variety of Arion ater in Kincar- 

 dineshire. — Although not a new county record, it will be 

 of interest to record that in 1891 I received from Mr. Wm. 

 Duncan, of Montrose, a fine living example of Arion ater 

 var. alba, which he had found on the banks of the North Esk 

 at Morphie. 



21. UNIO MARGARITIFERA IN BANFFSHIRE. The receipt 



of an example of the pearl mussel from the river Spey at 

 Aberlour, sent by Mr. Lionel W. Hinxman, of the Geological 

 Survey of Scotland, enables us to add this fine species to our 

 list for Banffshire. Another addition for the same county 

 is Helix rotundata, of which we have specimens collected at 

 Dufftown in November 1892 by Mr. Hinxman. At the 

 same time and place he found the following, which, however, 

 have already been placed on record by himself and other 

 friends: Helix hortensis var. Intca 12345, H. arbustorum, 

 Pupa cyliudracea ( = umbilicatd), Bulimus obseurus, Balea 

 perversa, Clausilia perversa ( = rugosa), Coehlicopa lubrica, 

 Arion ater, A. minimus, A. circumscriptus, and Agriolimax 

 agrestis var. sylvatica. 



22. Additional records for Easterness. — A collec- 

 tion of slugs and shells made by Mr. Wm. Evans at Dalwhinnie 

 and received by me on the 17th June 1S92 includes three 

 species additional to the vice-county: namely, Arion subfuscus, 

 d /. minimus, and Hyalinia fulva ; the other species sent with 

 them including .-Irion ater (small), A. circumscriptus ( = bourg- 



/dguati), A. hortensis ^ Agriolimax agrestis, Hyalinia alliaria t 



If. radiatula, and Coc/i/icopa lubrica (very young). The 

 elevation at which they were found was 1200 feet.
