NOTES ON SOME SCOTTISH FRESHWATER 

 RHIZOPODS AND HELIOZOA. 



By Prof. G. S. WEST, M.A., F.L.S. 



I. RHIZOPODS FROM THE ORKNEYS AND SHETLANDS. 



THESE were collected by my father in 1903 from various 

 bogs, ponds, and lakes, some of them being from the plankton. 

 The only species of interest are Heleopera petricola, Leidy, and 

 Hyalosphenia elegans, Leidy. I append a list of those species 

 observed, as it will augment our knowledge of the distribution 

 of these animals in the British Islands. 



Amoeba verrucosa, Ehrenb. Orkneys, Shetlands. 



Dactylosphtzrium radiosum (Ehrenb.), Blochmann. Shetlands. 



Arcella vulgaris, Ehrenb. Orkneys (Hoy), Shetlands. 



A. discoides, Ehrenb. Shetlands. 



Centropyxis aculeata (Ehrenb.), Stein. Orkneys, Shetlands. 



Difflugia constricta (Ehrenb.), Leidy. Shetlands.
