Notes on the Fauna of the Chipola Formation- XIV on the Occurrence of Bursa (Mollusca: Gastropoda), with Comments on the Genus

Abstract

The gastropod genus Bursa Roding, 1798 (type species: Murex bufonius Gmelin) has a long history in the New World, with two forms being known from the Eocene Talara Formation and Oligocene Chira Formation of Peru (Olsson, 1930, pp. 62, 63). By Miocene time the group had spread into the Caribbean and from then on flourished, with numerous species known from both the fossil and Recent faunas. Hitherto there have been no fossil representatives of Bursa reported from the southern United States, but in this paper two species are recorded for the first time.
