The Locality for Limnaea involuta Thompson. — 

 Cromagiaun Mountain is seven miles from Killarney, on the 

 road to Kenmare : there is no Cromagiaun Lake, as stated by 

 some conchologists. The Tarn inhabited by Z. involuta is 

 called Lough Crincaum on the one-inch statute map. It is on 

 a boggy plateau immediately under the apex of the mountain, 

 which is a strictly preserved deer forest ; there is no path up 

 and the climb is a severe one. The pool is apparently not 

 more than twenty feet across, and a quarter of it being situate 

 close against the precipice of the upper mountain is inaccessible. 

 My brother and I spent one and 'a half hours searching for 

 specimens, but unsuccessfully. I heard afterwards they are 

 only found under stones just where the stream runs out down 

 the face of the mountain, but there are certainly none there at 

 present, as neither the gamekeeper (who knows the shells well) 

 nor ourselves could find them. Perhaps owing to the unusual 

 heat they have retired into the mud in the middle of the pool.
