Hevwood Mount, Tenby, 

 20th Feb., 1899. 



Helix acuta monst. sinistrorsum at Tenby. — On August 29th, in company 

 with Mr. A. G. Stubbs, I paid a visit to " The Burrows " at Tenby. The weather 

 was wet, and the snails out in abundance, and on the edge of the golf-links, in a 

 fringe of short grass at the foot of a small sandhill, I took a great number of Helix 

 acuta, both the typical form and varr. arliculata, strigata, and bizona. My chief 

 prize, however, was a living sinistral specimen ; it is rather small, measuring 10 

 mm. in height by 5 mm. in breadth, but is apparently mature. I have never heard 

 of the occurrence of sinistral shells of this species before, and if this be the first 

 record I can only say that it is very singular that amongst the millions observed 

 on our coasts no others have been detected. — Fred Taylor {Read before the 

 Society, Nov. 9th, 1898). 



Note on Clausilia semidenticulata Pfr. — Of the specimens of this species 

 herewith presented to the Society's cabinet, the smaller ones were found at Mag- 

 nesia ad Mseandrum, the larger at Sochia in Asia Minor. For the identification of 

 these I am indebted to Dr. Boettger, of Frankfort, who writes me regarding them : 

 " They agree with the description and figures given by Kiister, though they are 

 larger ; this, however, does not prevent me from regarding them as CI. semidenti- 

 culata. They stand between CI. denticulata 01. and CI. thessalonica var. spreta 

 Gr." So far as I am aware, this is the first time this species has been taken on the 

 mainland of Asia Minor, having hitherto only been found on some of the Ionian 

 Islands and on the European side of the Bosphorus. — J. Bliss {Read before the 

 Society, April 12, 1899). 



Limax cinereo-niger in Carnarvonshire and Denbighshire. — This slug 

 is fairly plentiful in the woods of the Conway Valley in the neighbourhood of Tre- 

 friw and Bettws-y-Coed. In the early part of May, 1898, I collected several 

 specimens on the Carnarvonshire side of the river, from beneath the bark of dead 

 trees where they were always associated with Limax marginatus. I had few 

 opportunities of searching the woods on the Denbighshire side, but found an imma- 

 ture example beneath the bark of a dead ash at the Conway Falls. All the slugs 

 were referable to the variety litctuosa Moq. — Chas. Oldham {Read before the 

 Society, Jan. nth, 1899).
