observed associated with that species. Modiodicola has been 

 obtained in the horse mussel at various parts both of .the East and 

 West coasts. THOMAS SCOTT, Leith. 



Ilyoeryptus sordidus (Lievin) in Lochend Loeh, Edinburgh. 



This curious Cladoceran was found to be moderately common in 

 material collected some time ago with a hand net on the south-east 

 side of the loch. In form it somewhat resembles Daphnia. It 

 appears to be incapable of swimming, and therefore need scarcely be 

 looked for among the free-swimming organisms. Its usual habitat 

 is among the muddy vegetable debris that collects about the shallow 

 grassy margin of lochs, and, the test being rather hirsute, adult 

 specimens are often coated with mud. Ilyoeryptus was obtained in 

 considerable numbers in a similar gathering made on the south shore 

 of Loch Leven, Kinross-shire, in 1890. THOMAS SCOTT, Leith. 



BOTANICAL NOTES AND NEWS. 



Rediscovery of Sagina alpina (another plant of George Don's) 

 in Scotland. While ,botanising last summer on the Cairngorms with 

 Mr. G. Robertson of Burnside, Forfar, a small Sagina was gathered 

 on the steep cliffs of Corrie Sneachda, and also on a rock near the 

 waterfall which enters Glen A'an from Ben Muich Dhu (i.e. in 

 Easterness and Banff), which appeared to be Don's Sagina alpina. 

 Mr. Arthur Bennett says he does not see what else it can be. I 

 have compared it with Don's specimens in Herb. Brit. Mus., in Herb, 

 of J. E. Smith, and in Miss C. E. Palmer's collection, and have 

 come to the conclusion that it is the same plant. 



Some of Don's plants are only S. maritima, of which he was one 

 of the earliest discoverers in Great Britain. Some of his specimens 

 are cultivated ones ; and he says of the alpine plant that it keeps its 

 character in cultivation. It will be remembered that Don said he 

 gathered S. alpina near the summit of Ben Nevis in 1794. The 

 specimen in the herbarium of J. E. Smith in the possession of the 

 Linnean Society is dated 1803. In the same collection is a speci- 

 men of Sagina maritima labelled "New Sperg. saginoides, but perhaps 

 differs, J.E.S. Marshy ground on the coast three miles to the west of 

 Ardbigland in Galloway, J. Mackay, 1800." A specimen of Don's 

 from the Aberdeen coast, dated 1803, is worth further study; it 

 appears rather to be a maritime form of S. apetala, but I have seen 

 it only in bad light. 



Near Loch Morlich, Easterness, I gathered a plant which is, I 

 believe, identical with Calf ha radicals, Forst. It may be worth 

 noting that Ranunculus bulbosus was gathered near Boat of Garten, 

 in the same vice-county. G. C. DRUCE.
