Stki.fox. — Moliusca of Dingle Provwiilory 



33 



promontory or at its western end. It occurred at Milltown, near 

 Dingle ; ij\ the marshes at Smervvick, Inch, and V'entry ; also in 

 Lough Gill and the marshes west of this lake. Mr. Tomlin reports 

 it from the Cloghane district. The specimens from Milltown somewhat 

 resemble the real Planorbis spirorbis of continental authorities, but 

 possess a well marked reflected lip, which appears to be the chief 

 characteristic of the present species, and the one from which it derives 

 its name. 



P. fontanus (Lightfoot). — Common in the marshes west of Lough Gill, near 

 Strad bally, but not seen elsewhere. 



Physa fontinalis (L.). — Occurred in the habitats mentioned for the last 

 species, and in Lough Gill ; also in Lough Anscaul, on the southern 

 side of the main watershed of the peninsula. 



Aplecta hypnorum (L.).- — (T.)— Abundant in parts of the Stradbally marshes 

 and in the shallow marshy fringe of Lough Naparka. 'Sly specimens 

 from the latter place are the largest I have ever taken, lieported by 

 Mr. Tomlin from the Cloghane district. 



Paludestrina Jenkinsi Smith. — One of the most widely -distributed water- 

 snails in the promontory, and was taken at Milltown, near Dingle ; 

 in Lough Gill, and in the coastal marshes and drains at Smerwick, 

 Inch, and Stradbally. 



P. stagnalis (Baster.).— Under stones by the embankment, opposite Fer- 

 moylc House, and no doubt occurs elsewhere. 



Acicula lineata (Drap.). — Not so generally distributed as in most parts of 

 the west of Ireland, but no doubt frequent in shady mossy places 

 if specially searched for. In Glenfahan, a little stream-cut gully, 

 near Slea Head, this shell occurred in wonderful profusion. A few 

 bags of moss yielded over two hundred specimens of the brown and 

 white forms ; one of the latter was found to have the spire reversed. 

 This species was taken also in the gorge of the Finglass I'iiver and in 

 the woods at Fermoyle. 



Margaritana margaritifera (L.).—- N'ery common in the Owenmore, which 

 drains the valley above Cloghane. After a spate, in September, 1914, 

 many of these shells were found to have been washed from out of their 

 hiding places and cast up on the banks or left in shallow pools. 



Sphaerium corneum (L.).— Confined to the marshes west of Lough Gill, 

 near Stradbally. 



Pisidium SUbtruncatum Malm. — Only taken in the marshes at Stradbalh", 



and apparently confined to the lower ground. 

 P. casertanum Poll. — Not nearly so common as in \\'est ^Nlayo and other 



western districts, and was seen only in Lough Anscaul ; in bog -pools 



near this lake ; in the marshes at Smerwick Bay ; and at Stradbally. 

 P. obtusale Pfeiffer.— Common in the higher tarns in Coumaknock, on 



Brandon INIouxitain to 2,250 feet ; in Lough Tooreenmartin, Lough 



Doon, Lough Naiackaxr ; and also at sea -level in the marshes at Inch. 

 P. iiitidum Jen3^ns. — Ballinloghig ; Stradbally marshes ; marshes below 



Gallerus, in Smerwick Bay ; and in the tarns in Coumaknock to 2,300 



feet. 



P. pusillum (Gmelin). — (T.) — Under stones on the chils of Knocknabreestce, 

 at Brandon Head ; in the marshes at Stradbally ; and in the tarns
