Vol. 52, pp. 131-134 October 11, 1939 PROCEEDINGS or THE BIOLOGICAL SOCIETY OF WASHINGTON NATURAL HISTORY OF PLUMMERS ISLAND, MARYLAND. BY E. A. GOLDMAN and H. H. T. JACKSON. IX. Mammals.^ No systematic survey of the mammalian fauna of Plummers Island, or its vicinity, has ever been undertaken. The following list embraces 30 species that have been collected or observed, or whose presence on the island has been definitely determined by tracks, during a period of about 37 years. Owing to lack of field work it is not feasible to list all the mammals of the "main-land," as the tract of about 40 acres belonging to the Washington Biologists' Field Club on the adjacent Maryland shore is commonly called by club members. It seems desirable, however, to direct attention to an additional list of eleven species that are known from the general region and may be expected to occur on the island or the "mainland" area. In the preparation of these lists the card records kept at the island for many years, mainly by Dr. A. K. Fisher, have afforded an indispensable basis. Special acknowledgment is also due to Vernon Bailey who has brought together so much information in his "Mammals of the District of Columbia" (Proc. Biol. Soc. Wash., vol. 36, pp. 103-138, May 1, 1923), which has been freely consulted by us. The lists directed attention to many gaps in our knowledge of the mammals of Plummers Island and vicinity, gaps which it is hoped may be filled through an intensified interest of club members in this branch of natural history. 1 The following numbers of this series have been published previously: I (Introduction), Proc.
