There are lots of interesting questions about this genus, and it would be good if a big sample of shells were to be deposited in the NS Museum... > > Gayle said it was interesting that they were so widespread over all the rock walls of this historic fort located on Georges Island, in the Halifax Harbour. Maybe, because of it's location, & with not much human visitation, these snails thrived... they were EVERYWHERE, over all the outside rock walls of this historic Fort Charlotte, there on Georges Island., which is, not open to the public at all...but was, this year, for the 'Tall Ships' visitation & regatta, commemorating Canada's 150th... Maybe Andrew will take a trip over and check it out... > >> ================================================ >>> On 7/31/2017 11:50 AM, GayleMacLean wrote: >>> Yesterday, I had a fabulous visit to Georges Island to tour historic Fort Charlotte. >>> I was surprised to see that the outside rock walls of the buildings were covered with small snails.
