[Collected for the R.I. A. Flora and Fauna Committee.] 



Collections of Water-mites were made in the lakes near Rosses Point , 

 Lough Gill, Glencar Lake, and in streams near Ballysadare, resulting in 

 the capture of about twenty species. Some of the localities tried, 

 especially the lakes, were not favourable for these creatures, as certain 

 water plants amongst which they are usually to be found were scarce or 

 altogether absent. A few of the species have not 3'et been satisfactorily 

 identified, especially in the genera Eylais, Lebertia and Sperchon. 



The most interesting water-mite found is undobutedly Arrhcniirus 

 Mcebii, now recorded for the first time from the British Isles. It was 

 originally discovered a few years ago by Dr. Piersig in a lake in the 

 Black Forest, and since that time it does not seem to have been re- 

 corded from any other locality. Hydrachna distincta is also an addition to 

 the British records, and a new form of Eylais was discovered in Lough 

 Gill. 



Considering the smallness of the collections the results are satisfactory, 

 and no doubt careful dredging in the lakes would bring to light many 

 additional species.
