CHECKLIST OF RECENT MOLLUSCA OF WYOMING, USA

Dorothy E. Beetle 1

Abstract. —Wyoming lacks a rich molluscan fauna clue to its considerable elevation, extremes of temperature, the short period between killing frosts, scanty moisture, and intermittent creeks. Recent mollusks found in the state total 42 genera (109 ), including 6 genera (23 species) of bivalves, 15 genera (42 species) of freshwater gastropods, and 21 genera (44 species) of land gastropods. Synonymy, the counties in which each species was collected, and habitat notes are given.
