During the past year (1906) I made an attempt to find out 

 if any records relating to Hydrachnidae existed in the Trans- 

 actions of the various Natural History Societies in Scotland. 

 Communications were sent to the secretaries of these societies, 

 but the result was disappointing, as only four replies were 

 received — viz., from Mr A. M. Rodger, Perthshire Natural 

 History Museum ; Mr A. B. Johnston, Andersonian Natural- 

 ists; Mr S. Arnott, Dumfriesshire and Galloway" Natural His- 

 tory Society ; and Mr Alex. Eoss, Natural History Society of 

 Glasgow. These gentlemen reported that their Transactions 

 contained no Hydrachnid records. I take this opportunity of 

 thanking the gentlemen named for their cordial assistance in 

 this matter. It may be fairly safe to assume that practic- 

 ally no records exist other than those appearing in Part IV., 

 Vol. V. of this Society's ' Transactions ' and Mr Soar's list in 

 the ' Journal of the Quekett Microscopical Club ' in November 

 1900. Possibly an isolated record may exist here and there, 

 and if so, I shall be glad to be informed of it.
