10 Mr. J. N. llalucrt on Irish Iljdrachnid'i. 



^s> September 1899, in Upper Lough Erne, Co. Fermanagh. 

 The specimens were mixed with the commoner Mideopsis 

 orbicularis and were so overlooked. I have since taken the 

 species in Lough Gill, Co. Sligo.

 Co. Sligo, in company with Panisus Michaeli. A third

 near MuUingar in April 1903.

Pool by the side of Lough Leane, Kilhirney, June 1905. 



Fortunately the single specimen taken is a male and shows 

 the characteristic moditication of the fourth pair of legs, as 

 described and figured by Dr. Thor. Tiiis appears to be the 

 first record of the species since the original record from 

 Norway, and it seems to have been omitted from the volume 

 of the 'Tierreich' (1901) treating of the Ilydrachnida.
