In this paper I wish to refer to some of the more interesting Turbellaria found during the months of July, August, and September 1905 at Ardeonaig on Loch Tay, and during August and the early part of September 1906 at Tarbet on Loch Lomond.
I also wish to describe in more detail a newly discovered Kalyptorhynch, and to put forward some observations on the origin of the nematocysts in some Microstoma lineare.
The opportunity of working on these forms occurred in connection with the work of the Scottish Lake Survey under Sir John Murray, to whom, for his unfailing kindness, I owe a very deep debt of gratitude.
