A FURTHER CONTRIBUTION TO OUR KNOW- 

 LEDGE OF THE RHIZOPODS OF SCOTLAND. 



By James Meikle Brown, B.Sc, F.L.S. 



In continuation of my investigations on the Freshwater 

 Rhizopoda of Scotland, of which reports have already been 

 published (see 1 and 3), large quantities of material were 

 collected during July and August 191 2. The gatherings 

 were taken principally from various localities in the counties 

 of Argyll, Inverness, Perth, and Elgin, and consisted, as 

 before, of bog mosses and ground mosses. 



On comparing the lists which follow, with those already 

 published (1, 3, 12), it is remarkable what close similarity 

 exists between the species obtained from similar situations ; 

 but, as is to be expected, Mr Wailes' lists (12), dealing 

 largely with lake and pond forms, contain some species 

 absent from my material. This seems to indicate that 

 while some species are naturally more plentiful than others, 

 nearly all are widely distributed, while a few exceptional ones 

 at present appear to be scarce or local, e.g., SpJienoderia 

 macrolepis.
