III.— THE INVERTEBRATE FAUNA OF THE INLAND WATERS 

 OF SCOTLAND. Part II. By Thomas Scott, F.L.S. (Plates V., VI.) 



In this, the second report on the Invertebrate Fauna of Scottish Inland 

 Waters, reference is made to the following lochs : — 



Loch Leven, Kinross-shire. 

 Raith Lake, near Kirk- ^| 



caldy I Fife- 



Camilla Loch, [ shire. 



Loch Gelly, J 



Loch Strathbeg, Aberdeenshire. 



Loch Achnacloich, 

 gordon, Ross-shire. 



near Inver- 



Loch Ness, \ the Caledonian 

 Loch Oich, > Canal Lochs, 



Loch Lochy, j Inverness-shire. 

 Loch Balnagowan, ") Lismore 

 Loch Kilcheran, > Island, 

 Loch Fiart, ) Argyleshire. 



Loch Hempriggs, ) near Wick, 

 Loch Wester, j Caithness. 

 Loch Harray, 

 Loch Stenness, 



Orkney. 



Only a short visit, however, was made to all, except Loch Leven, and 

 even the examination of Loch Leven cannot be considered as being in any 

 way exhaustive ; to arrive at a fairly accurate knowledge of its rich 

 invertebrate fauna, several visits would require to be made. The results 

 of our examination of these lochs has nevertheless proved highly interest- 

 ing. 



I propose in the following report to describe my examination of the 

 lochs named in the order in which they are arranged. In preparing this 

 report numerous works have been consulted, some of the more important 

 of which are as follows : —

v., vi.). }

To my ever kind friend, Professor G. S. Brady, I am greatly indebted 

 for much valuable help. I have also to acknowledge the kind encourage- 

 ment accorded to me in many ways by Dr T. Wemyss Fulton and Mr W. 

 Anderson Smith while carrying out, the investigation of the inland waters 

 of Scotland. Professor W. C. M'Intosh has favoured me with the names 

 of some of the Loch Leven Annelides. J. B-ae, M.D., and Mr R 

 Kidston, F.RS.E., F.G.S., have kindly undertaken the examination of 

 the Loch Leven Diatomacea, and have prepared a list of species. I have 

 also to acknowledge the active and kindly co-operation of Captain R. E. 

 Simpson, master of the 'Garland,' both in connection with the investiga- 

 tions here referred to and in our regular marine fishery investigations. My 

 son, Mr Andrew Scott, has prepared the drawings which accompany this 

 paper.
