 IX., X.) 



During the past year a considerable number of the fresh water lochs 

 of Scotland have been visited and examined. They include all, or nearly 

 all, the lochs on the Island of Barra (Outer Hebrides); three of the 

 principal Lochs of North Uist; three Lochs in Perthshire ; one near East 

 Tarbert, Argyllshire ; and three in the vicinity of Glasgow. Not a few 

 of them contain trout, and are more or less frequented by anglers, Tho 

 following are the names of the various lochs referred to, and which are 

 described in this report : —

In describing the results of the examination of these lochs, I propose to 

 take them in the order in which they are here arranged. It is not in- 

 tended to describe in detail the various organisms obtained in each loch. 

 A summary only of them will be given, along with notes on a few of the 

 more interesting species ; and at the end of the description of each group 

 of lochs a Table will be added containing the names of all the species 

 identified, and showing their distribution in the various lochs described.
