Part III. — Seventeenth Annual Report 



The Invertebrate Fauna Collected by Hand-Net. 



Amongst the Crustacea collected about the shores of Loch Doon by 

 means of the hand-net, several rare species were observed — one of which, 

 Cyclops nanus, appears to be new to Britain ; Cyclops languidus and 

 Lathonura rectirostris were also obtained here for the first time in 

 Scotland. Other rare species obtained at Loch Doon were Canthocamp- 

 tus schmeilii and Maraenobiotus vejdovskei. A full list of all the species 

 of Crustacea observed in the hand-net gatherings from Loch Doon is 

 contained in the following Table ; —
