The Scottish Naturalist. 163 



Lepidoptera of Sutherland.— In the following note are mentioned those 

 species observed by me in August, in Sutherland (meaning by that name the, 

 province so called in the lists of Scottish insects), which' have already been 

 mentioned in Lepidoptera Scotica, without being given under that province, 

 owing to want of information. I follow the names and order given 

 in the list : — Vanessa urticce, abundant ; Efinephde janira, abundant ; Pieris 

 brassier, one specimen, Lyccena icarus, common ; Saturnia pavonia, larvae 

 and cocoons ; Bombyx rubi, larvae; Bombyx quercus, L. cocoons ; Leiocatnpa 

 dictiBoides, one larva in Strathnaver ; Lophopteryx camelina L. one larva in 

 Strathnaver ; Orgyia antiqua, larvae ; Dasychira fascelhia, one larva. The 

 remaining species will be mentioned in their proper places in the list. — JAMES 

 W. H. Traill, Aberdeen, August, 1873. 



Vanessa Antiopa.— Two specimens of this species were seen near Dunkeld 

 last spring.— F. Buchanan White. 



Helix ericetoium in Sutherland:— While botanizing on the north coast 

 of Sutherland, in August, I found this species of snail very abundant on the 

 sandy banks at Malvich and Farr, and doubtless it occurs in similar localities 

 elsewhere along the coast. The northern limit is given in Jeffreys' work as the 

 Hebrides, no island being specified. At Farr I also found the shells of 

 Bulimus acutus very abundant. — James W. H. Traill, Aberdeen. 



A LIST OF THE SCOTTISH LAND AND FRESH-WATER 

 MOLLUSCA, WITH HINTS ON COLLECTING. 



By F. BUCHANAN WHITE, M.D., F.L.S. 



A S subjects for study the Land and Fresh-water Mollusks, 

 either dead or alive, are. well worthy of attention. In a 

 living, state they may be kept, and their habits observed and 

 recorded ; when dead, they have this advantage over many 

 other groups of animals that their shells may easily be preserved 

 without losing any of the beauty of form, and little of the beauty 

 of colour; while to the possessor of a microscope their palates 

 supply abundance of material for work and investigation. 

 Moreover, to the naturalist possessed of but little time to devote 

 to his favourite pursuits, the British species, being only about 130 

 in number, have the additional advantage of not being a group in 

 which he need despair of attaining anything like a perfect col- 

 lection, and are besides (as regards the majority at least) 

 obtainable at all seasons and in most places ; while to him who 

 is not over burdened with this world's pelf, the apparatus re- 

 quired in their capture and preservation, need cost but little. 

 To the casual observer, a few (often indeed too many) slugs,
