Porifera. — Sponges were collected in Lough Gill at Rock- 

 wood on the Co. Sligo side of the lake, and at O'Rourke's Castle 

 on the Leitrim side. 



Three species were obtained — namely, Spongilla lacustris 

 (Linn.), Ephydatia fluviatilis (Linn.) and Ephydatia mulleri 

 Lieberkiihn. 



Mr. Praeger, who collected the samples that were preserved, 

 noted that the sponges were much scarcer on the limestone at 

 O'Rourke's Castle than on the Metamorphic rocks at Rockwood. 

 All three species were taken at the latter place, while E. mulleri 

 alone was found on the limestone. 



This is the first record of fresh-water sponges for the counties 



of Sligo and Leitrim.
