Abstract
THE resemblances between the Tertiary faunas of the West Indies and those of the Mediterranean region have long been noticed and have been taken to indicate the former existence of shallow water across the Atlantic from the West Indies to Northern Africa, along which the migration of animals could take place. This subject, so far as the Miocene and Pliocene periods are concerned, has been more fully investigated by W. P. Woodring (Bull. Geol. Soc. America, 35, 1924, pp. 425, 867), who finds that the resemblance of the Miocene mollusks of the West Indies to those of the Mediterranean area is even closer than was formerly supposed-the resemblance being particularly striking to the fauna of the Piedmont basin of Italy. The similarity reached its maximum in the Helvetian period, when the Miocene transgression of the sea was at its greatest in both regions.
