The University of Michigan Biological Station (UMBS), located in Cheboygan County on Douglas Lake, about 15 miles (24 km) south of the Straits of Mackinac in the center of the lower peninsula of Michigan, has been a prductive institution for scientific research and for training biologists for over 75 years. Thousands of students have trained there, and hundreds of research papers have been published on the local flora and fauna. For animals, these papers have dealt with many aspects of biology, such as taxonomy, life histories, ecology, behavior, morphology, cytology, parasitism, etc. But, nearly all papers on terrestrial mollusks have been restricted to species occurrences and taxonomy, with several papers giving habitat information. Nevertheless the area has a rich and abundant land snail fauna, and land snails are interesting subjects for all types of biological studies. Perhaps one reason for the neglect of UMBS area land mollusks is the lack of a readily available, up-to-date treatment of their taxonomy. The objective of this publication is to present a list of the land snails of the UMBS area, and to place these mollusks in a modern frame of classification. For the purposes here, the UMBS area includes the counties of Emmet, Cheboygan and Presque Isle, an area of some 2,200 square miles. This list is based on collections made during the summer of 1986, and on specimens collected previously and now part of the collections of the Mollusk Division, Museum of Zoology, The University of Michigan.
