USNM Curators Annual Report - Department of Mollusks: Annual, 1892-1893

As a collector, knowing what you don't have can be just as important as what you already have in your collection. Especially if your goal is to have a truly comprehensive set of specimens. From the progress of the Department of Mollusks to identify and catalog duplicates in the previous year, curator William H. Dall reports on the fruit of those labors as well as work with Tertiary Fossils and special reports drawn up for four different government organizations including the US Navy, the Revenue Marine and the Department of Agriculture plus several expeditions. Join up with other volunteers to transcribe this material and help us connect this material with other biodiversity material in museums and research centers all over.
