Remarks.—Tliis, with the following species, was discovered and communicated to me, in 1879, by Mrs. Andrews, who tlins described the locality in which the two siDecies were found.:— " The Cliiis rise up 200 feet on the south side of the river,— they are very steep and rocky, face the north, are almost always shady, damp, and covered with mosses and ferns. I collected the shells on the ledges of the rocks among the dead leaves, at an elevation above the river of about 100 feet. I have not found either of the spiecies in any other ; Mr. J. H. Thomson, to whom I submitted sjDecimens, sent to me examples of the same species collected by him, "on a high rocky ledge, covered with old trees, at Tiverton, Ehode ;.
