Pennsylvania is one of our better collected and studied states in the field of malacology. With two well known centers, the Academy of Natural Sciences and Carnegie Museum at either end of the state, many noted malacologists have found occasion to collect and study in Pennsylvania. In addition to numerous professionals who have been associated with the state, there has been a small, but noteworthy, group of amateur collectors, particularly in the south-central and southeastern portions. Although there has never been a complete summary of the molluscan fauna of Pennsylvania, there .have been basic summarizations prepared for every group except the Sphaeriidae.
