A few specimens of Ilyocryptus sordidus were obtained in a gathering 

 of bottom material from the shallow water at the head of the loch. It 

 appears to be a moderately common species where the conditions are 

 favourable , it was very common in June 1890 among vegetable mud on 

 the south shore of Loch Leven, Kinross-shire ; and in July 1892 by the 

 side of Lochend Loch, near Edinburgh.

 from the shore at Brinacory.
