On the extant type material of Cardisoma hirtipes Dana, 1851, and Cardisoma obesum Dana, 1851 (Crustacea: Brachyura: Gecarcinidae)

Two boxes in the U.S. National Museum of Natural History, Smithsonian Institution, were found to contain the dried type material of the land crabs Cardisoma hirtipes Dana, 1851, and Cardisoma obesum Dana, 1851 (Gecarcinidae). The types of the common Pacific land crab, C. hirtipes, were believed to have been lost and a neotype had been designated in earlier revisions. Cardisoma obesum Dana, 1851 is currently regarded as a junior subjective synonym of Cardisoma carnifex (Herbst, 1796).

Key words
