105 Ross West. — A printer's error has to be corrected in record of Pisiditim 

 species at Gairloch (see [ourn. of Conch., 1915, vol. xiv., p. 312), wherein 

 P. nitidum is mentioned instead of P. milium from Gairloch. The record 

 in the books is of P. milimn, and the Hon. Recorder is grateful to Dr. 

 James Ritchie for pointing out this misprint {Scottish Naturalist, October, 

 1915,- p. 310).

 of Kildare, I4lh March, 1918, two (Lance-Corporal Ernest Stainton, 2/ist 

 Fife and Forfar Yeomanry). 



"Ground" Clausilias. — Of our British Clausilias only one {rolphii Gray) 

 can, I think, be regarded as a normally " ground " species. Its favourite habitat 

 appears to be at the foot of the stalks of the common nettle, and if it ascends trees, 

 it only does so quite exceptionally. Our other species of Clausilia may be said to 

 prefer a situation off the ground — rocks, trees, walls, etc., though, no doubt, cases, 

 e.g., laminnta Mont., occur when they are found actually on terra firma. It may 

 be interesting to record that in August, 1912, I came across a remarkable colony 

 of "ground" Clausilias. Not all of the species are regular ground haunters ; 

 one at least [orthostoma Menke) is much more commonly found on smooth- 

 barked trees, while cana Held is almost ubiquitous in its choice of habitat. The 

 locality was a steep mountain side, facing north, above Busteni, in West Roumania, 

 the height perhaps 4,000 feet, the ground a patch of nettles and other low-growing 

 herbs in the middle of a smooth grassy clearing, about half-an-acre square, sur- 

 rounded by pines above and below. No place would have looked more unlikely 

 for mollusca, which detest pinewoods, and no Clausilia will ever ascend a pine if 

 it can possibly help it. Yet in this patch, perhaps two yards square, something 

 suggested a search, and in three-quarters-of-an-hour I obtained eighty-nine speci- 

 mens and eight species of Clausilia (other genera are omitted) namely : — cana 

 Held (Alinda) 6 ; dtibta Drap. (Iphigenia) il ; elata Zieg. (Uncinaria) 16 ; fallax 

 Rossm. (Alinda) 38 ; filograna Zieg. (Graciliaria) 8 ; latestriata Bielz (Piro- 

 stoma) 7 ; orthostoma Menke (Clausiliastra) i ; plicata Drap. (Alinda) 2. All were 

 living specimens. CI. fallax I have often found in similar situations, once near 

 the Roterthurm Pass, in South Hungary, in very hot weather, a couple of inches 

 under the ground at the roots of nettles. Bielz (Fauna Siebenbiirgens, 1867, p. 

 156) states that it occurs on old tree trunks under loose bark, more rarely on the 

 ground beneath fallen leaves and rotten wood. I have taken it in association 

 with Alopia regalis M. Bielz on a rock face at the northern foot of the Pialra Mare. 

 CI. filograna Zieg., one of the tiniest of Clausilias, is also a ground-living species, 

 though it did not occur to me on the occasion referred to. — Rev. A. H. Cooke,
