Land snails of Ulithi Atoll, Caroline Islands: a study of snail accidentally distributed by Man / by Harold W. Harry

During the Second World War I had occasion to visit briefly Mogmog Islet, Ulithi Atoll, Western Caroline Islands, and to collect the land snails reported herein. The collection was divided, and one part, including all specimens of several less abundant species, was sent to the late Dr. C. Montague Cooke, Jr. of the Bernice P. Bishop Museum. In unsorted "sweepings" he found a few species which I had over-looked. It was his intention to publish the data in a paper on comparative faunal studies of the Mid-Pacific Islands, but death intervened. Some years later I had the opportunity to study more carefully the set I retained, using the extensive collection and library at the University of Michigan Museum of Zoology.
