turned inland & S. to Lon-na-h'Inse the lochan I believe Dr. Macan (of Wray Castle, Windermere) is reported in Journal of Conchology for May 1954 to have taken the snail Planorbis vortex.  Found the lochan to have a clean sandy bottom & a few plants (Potamogeton, Chara sp. & Myriophyllum) gathered in the drift or growing in shallow water, but at the N. end (the only part examined!) saw no sign of any snails.  Just E. of the main lochan I found a flooded swampy annexe filled with dense vegetation from Myriophyllum to Marsh Marigold, Glyceria fluitans & Sedges & in water 6" to 1 ft. deep found what appears to me to be a very large vortex-like form of Planorbis leucostomus, but the matter wants v. careful looking into as these shells are very like vortex.  In an almost dry marshy place N. & NW. of the lochan saw patches of a queer black-headed rush = J. balticus! AWS.  I did not recognise & took specimens.  It is superficially like Schoenus nigricans, but of quite different growth & not in clumps.  Next went back NW. to coast & after tea down the W. coast for about a mile & then turned E. for home via N. shore of Loch Borralaidh, seeing much Dryas, Antennaria, Carex capillaris & a few plants of Thalictrum (on the rocky scarp) & so home at 6.30 PM.  In the thatch of a ruined cottage Daisy spotted our first plant of Groundsel (Senecio vulgaris) we had seen in Sutherland.  Swept or saw the following insects:-
