Ill.—THE INVERTEBRATE FAUNA OF THE INLAND WATERS 
OF SCOTLAND. Parr II. By Tuomas Scort, 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. Loch Ness, the Caledonian 
Raith Lake, near Kirk- } Loch Oich, Canal Lochs, 
caldy jae Loch Lochy, Inverness-shire. 
Camilla Loch, f shire. Loch Balnagowan, ) Lismore 
Loch Gelly, J Loch Kilcheran, Island, 
Loch Strathbeg, Aberdeenshire. Loch Fiart, Argyleshire. 
Loch Achnacloich, near Inver- | Loch Hempriggs, | near Wick, 
gordon, Ross-shire. Loch Wester, ; Caithness. 
Loch Harray, 
Loch Stenness, \ Orkney 7 
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 :—

To my ever kind friend, Professor G. 8. 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. Rae, M.D., and Mr R. 
Kidston, F.R.S.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 mm 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.
