1903' Kank. — Irish Fresh-water Entomostraca. 215 



Hyalodaphnia cucullata, G.O.S. {kahlbergensis Sch.)— Upper L. 



Krne. Taken first there by Dr. Creiglitou. 

 Scapholeberis mucronata, Mull.— Lakes and bogs in Co. 



Monaghan ; Marsh near Favour Royal in Tyrone ; Upper Lough 



Erne ; R. Boyne near Navan ; Kilmacduagh in Clare ; Lough Corrib 



(iv.) ; Lough Gur ; Lough Mask. 

 Simocephalus vetulus, Schoed.— Everywhere abundant. 

 S. exspinosus, Koch. — Drumreaske, Co. Monaghan ; Fermoyle, Co. 



Kerry (Scourfield). 

 Ceriodaphnia reticulata, Schoed. — Glaslough and Drumreaske, 



Co. Monaghan ; L. Unshin near Ballyshannon (ix.) 

 C. tneg'alops, G.O.vS. — Drumreaske, Co. Monaghan ; nearGalway (vi.); 



Lough Gur, Co. Limerick. 

 C. pulchella, G.O.S.— L. Neagh, south shore; Upper L. Erne; 



Glaslough ; Lisdoonvarna ; Boyne Canal; Lough Gur, Co. Linierick. 

 C. quadrang-ula, O. F. Mull, {ptilcheila in Mr. Creighton's list). — 



L. Nabrackalan near Ballyshannon (ix.) ; lakes at Clifden, Conn- 



emara 

 C. faticaudata, P. E. Mull. — Drumreaske, Co. Monaghan. 



{Bosmina lougirostris^^wW. — Recorded from Clonhaugh L-, nearMuUingar. 

 Requires confirmation). 



Bosmfna longicornis, Schoed. — Boyne Canal. 



B. long'ispina, Leyd. — Mr. Scourfield thinks that the examples 

 hitherto classed under this designation may probably be referable, 

 in large part at least, to some of the forms included by Lilljeborg 

 under obtusirostris. I prefer provisionally to retain them under this 

 designation, leaving future captures to be relegated to their proper ' 

 position in Lilljeborg's classification. L. Melvin (ix.), L. Bollard, 

 Connemara (vii.) ; L. Neagh, Lisdoonvarna (vii.) 



B. obtusirostris, G.O.S. — Specimens I took at Kylemore, Connemara, 

 with short straight rostra, almost certainly are referable to this 

 species. 



var. lacustris, Lillj.— L. Mask, abundant. 



B. DoIIfusli, Moniez.— Specimens of this, with the claws of the post- 

 abdomen not dentate, I captured in L. Arrow, and in the lakes of 

 Ballinahinch and Kylemore, Connemara. 



B. mixta, Lillj., var. humilis, Lillj.— Upper L. Erne (identified by 

 Lilljeborg), fairly abundant ; L. Oughter, a few. I am able to report 

 the occurrence of this northern species abundantly in Lough Conn, 

 Co. Mayo. Summer examples, taken June 30th, correspond in 

 character to figs. Sand 9, tab. xli. of Lilljeborg's Cladocera Suecicc : 

 the spines at the infero-posteal angle of the test, however, being 

 longer, and so differ from summer specimens from Lough Erne. 



B. core&oni, Baird.-Upper L. Erne, a few with the preceding species 

 (identified by Lilljeborg.) Dr. Creighton first discovered a Bosmtna 

 in L. Erne, which was presumed to be referable to B. coregoni, but 

 probably must have belonged to the preceding species.
