The attached photographs show a site on the cliffs at Walton-on-the Naze below Sunny Point TM264231 and what I believe to be the Snail Cernuella (Helicella) virgata, the sandhill/dune snail.
The promenade here is part private, part public owned. At he point where they meet the seawall funnels southerly winds and windswept sand onto the base of the cliff creating a mini dune like environment.
A few years ago I found that this snail had taken up residence there with just one or two specimens present. On 10.11.11 a small colony was noted some 30+ being recorded.
It would be interesting to know how on earth they arrived at the site, which is small and isolated from any dune area by about a mile
