NOTES ON SOME FRESH AND BRACKISH WATER 

 ENTOMOSTRACA FOUND IN ABERDEEN- 

 SHIRE. 



By THOMAS SCOTT, F.L.S. 



IN the "Annals of Scottish Natural History" for October 

 1899 I submitted a few notes on some Entomostraca which 

 had been obtained on the shores of a number of the lochs 

 of Aberdeenshire, by means of a hand-net, during the pre- 

 ceding summer. 



Some time after the publication of these notes I made 

 the acquaintance of Mr. R. M. Clark, B.Sc., F.L.S., Aber- 

 deen, and learned that he had already, in 1898, examined 

 several of the lochs and tarns in the western part of the 

 county a part which had been somewhat beyond my reach. 

 He informed me that the materials he had then collected 

 were still in his possession, and very generously permitted 

 me to overhaul them for any Entomostraca they might 

 contain. Some of the lochs and tarns represented by the 

 o-atherino-s in Mr. Clark's collections are situated at con-

siderable altitudes, and this circumstance added very much 

 to their interest. The lochs represented included, amongst 

 others, Loch Kandor, Loch Vrotachan, Loch Callater, Loch 

 Phadruig, and Loch-an-eion, all to the southward of Castleton 

 of Braemar ; and Loch Etichan and a tarn near Loch Avon, 

 which are situated to the north. There were also gatherings 

 from Loch Kinord, Loch Davan, and some others nearer the 

 city of Aberdeen. 



But besides the examination of these gatherings from 

 the highlands of Western Aberdeenshire, I have also, on 

 three different occasions during the past autumn and spring, 

 examined a number of the pools situated on that portion 

 of the Links of Aberdeen known as the King's Links ; the 

 part where the pools referred to occur is near the north end
