ENTOMOS TRA CA, 



BY W. F. DE V. KANE, D.L- 



Advantage was taken of a boat at Glencar to investigate the 

 entomostracan fauna of the lake. The plankton largely consisted of 

 Diaptomtis gracilis and Daphnia hyalinia, var. ^aleata; one or two examples 

 of Cyclops phaleratus were noticed. Among the weeds several species were 

 collected, such as Lymceiis guadrangularis, L. costatiis (abundant), Alonella 

 exigiia, Chydorus sphctrictis, and C. ovalis.

Three of the eight Irish species of fresh-water leeches were found by 

 the naturalists at Sligo: — 



PIsclcoIa gcoinetra, Linn.— Glencar lake. The fourth Irish record 

 for this scarce species. 



Clossiphoniacomplanata, Linn.) Lough Gill. These two species 



> are doubtless common through- 

 Haemopis cangruisugra, Linn. ) out Ireland.

ACTINOZOA 



BY W. H. GALLWAY. 



There was not much opportunity for Anemone-collecting, as there were 

 very few rock-pools, the shore touched upon bemg mostly sandy. I can 

 therefore only record the capture of five specimens of Bunoiies getnmacea 

 (Gosse) in the rock-pools at the foot of Knocklane — one full-grown 

 specimen, two half-grown, and two about one-third, all with the columns 

 coloured rose-pink. 



On introducing the animals to my tank, I had the pleasure of witness- 

 ing the birth of a young Anemone, which soon attached itself to the rock 

 and expanded its tentacles. 



In addition to the foregoing, I only noticed Actinia 7nesemhryanthemiim, 

 which was common, and also a few specimens of Bufiodes crassicornis.
