226 The Irish Naturalist, [September, 



L. truncatula, Miiller, — Inside the long tunnel on Glengarriff road 

 there are numbers of a very minute form, also some of a larger type on 

 wet rocks near the tunnel, at an elevation of 1,000 feet. Common on mud 

 near Sheen Waterfall ; and in a swampy place near Loo Bridge, in com- 

 pany with Vertigo antivertigo. Stream near the Tunnel, Upper Lake, 

 Killarney ; and in Strickeen Wood (Farran). 



Planorbfs splrorbis, Miiller.— Ditch near Cloonee Lakes. At 

 Muckros and Lower Lakes of Killarne}- it is fairly common, but of small 

 size (C. & C.) 



P. contortus, L- — A few specimens of small size in Glena Bay, 

 Lower Lake, Killarney (C. & C). 



Ancylus fluviatilis, Miiller.— Occurs sparingly in the lakes and 

 mountain streams about Kenmare. Very common at Muckros, and Lower 

 Lake, Killarney (C. & C). Var. captiloides, encrusted with a black deposit, 

 occurred in a small stream running into Auger Lake, Gap of Duuloe 

 (Chaster). Elsewhere«all observed were var. gihbosa. 



Acme If neata, Drap. — A few typical examples in shakings of moss and 

 Marckantia from Mucksna Wood (Standen). Very abundant amongst 

 moss and dead leaves in Tore Woods : many very richl}- coloured t3-pe, 

 and some beautiful var. alba ; also found near Tore Cascade (C. & C. . 



Hydrobia Jcnkinsi, Smith. — Mr. Welch found this in abundance, 

 last Ma}', in a stream near Rough t}' Bridge, and from the smallness of the 

 specimens thought they might possibly be a dwarf form. But we 

 satisfied ourselves that the shells now present in the river are the adult 

 form of the shells seen in Ma3^ They are slightly smaller than ordinary, 

 and of a more slender type. The species is extremely plentiful, but 

 only a very small proportion are the carinate variety. 



H. ulvae, Penn.— A few in the Roughty River, in company with H. 

 Jenkinn. 



Pisldium pulchellum, Jenyns. — One specimen, Galway Bridge 

 (Welch). Five very beautiful specimens, Upper Lake, Killarney (Standen).

 Mountain, Killarney (Collier).

 on each side of Middle Cloonee Lake (Welch). Common on mud of 

 river at Sheen. 



P. milium, Held.— Common in Middle Cloonee Lake (Standen). A 

 few on mud of river at Sheen. 



P, pusillum, Gmelin. — Large dark specimens in Auger Lake, Gap of

 deposit, in ditch running into Loo River, near Loo Bridge Ditch near
