A magnificent, uncrushed, complete adult internal mould, beautifully preserved on both sides with a very fine complete ventral horn or lappet. The peristome is complete on one side, and almost complete on the other. The sutures, including the last show well and the body chamber with superb ribbing to the end, occupies 2/3 of the final whorl. Much of the matrix figured by Arkell, 1957 and Buckman, 122, has been removed and some test is present in the umbilicus. From Swindon, Wiltshire, England.
