142 THE SCOTTISH NATURALIST 



The Marsh Slug in Banffshire. I have had two consign- 

 ments of slugs and snails from Miss J. Gowan of Cullen, taken at 

 that place on the 24th and 29th April. The latter one contained a 

 very young example of Agriolimdx Icevis, a species of which I have 

 never seen a record for the county. The other species were A. 

 agrestis, very dark examples of var. reticulata, Arion ater var. 

 nigrescens and fasa'ata, A. hortensis, A. circumscriptus, A. inter- 

 medins var. grisea, Vitrina pellucida, Pyramidula rotundata, Zua 

 lubrica, Helix hortensis var. lutea 12345, Helicigona arbi/stonan 

 type, and Hyalinia nitidula. I shall welcome assistance of this 

 kind from any locality in Scotland. W. Denison Roebuck, 259

Occurrence of Testacella scutulum in Perthshire. 



Specimens of this interesting slug were brought to me on 26th 

 April from Dunbarney, near Bridge of Earn (Perthshire Mid. 

 v.c., 88), where it seems a colony has been established in the 

 gardens for some years. This is the first record for Perthshire, the 

 only other Scottish authenticated records being Renfrewshire, 

 76; Fife and Kinross, 85; and Stirlingshire, 86. The specimens, 

 which are of an exceptionally bright yellow colour, have been 

 examined and authenticated by Mr J. W. Taylor, and are now in 

 the Voucher-Collection of the Conchological Society at Manchester. 

 Mr Roebuck asks me to say that he will be glad if local observers 

 will keep a lookout for this species in other vice-counties, and also 

 for T. haliotidea, Drap., which has hitherto only been authenticated 

 in Scotland from Kirkcudbrightshire, 73. Henrv Coates, The

Pood Value and Medicinal Use of Shellfish, etc. In the 



present times of scarcity, it seems a pity that no general attempt has 

 been made to utilise shellfish as food. It may perhaps, therefore, 

 be worth drawing attention to the fact that Pholas is excellent eating, 

 also that several species of Mollusca not commonly used are never- 

 theless edible. Mactra subtruncata was formerly used as pig-food 

 in Arran (see Woodward). The Limpet, they tell me here, has a 

 medicinal action on pigs (aperient), and must, therefore, only be 

 used occasionally. Cats can be fed on the Limpet boiled, and the 

 fishermen eat it either boiled or raw, while some people pickle it in 

 vinegar. 



The late Dr Clayne, of Castleton, Isle of Man, frequently pre- 

 scribed the seaweed Iridea edulis as a vermifuge. This seaweed is
