To those students interested in the palæontology of Maryland, United States, it may be welcome intelligence to know that the “John Finch Collection” of Tertiary Mollusca from that State, including some of the type-specimens figured and described by Thomas Say in 1824, is in the possession of the British Museum. This fact has only recently been recognized through the examination of certain documentary evidence connected with the history of the fossil invertebrate collections contained in that institution.
