Timothy Abbott Conrad was a New York geologist and malacologist who contributed to the New York Geological Survey in the 1830s. He was a frequent contributor to journals such as the "American Journal of Science" and "Journal of the Philadelphia Academy of Science," and also oversaw the posthumous publication of the last part of Thomas Say's "American Conchology." In this work, Conrad writes about the large variety of freshwater shells throughout the Midwestern and Southern regions of the United States, including some new species he names. Each plate is accompanied by a description and Conrad's observations. The 8-page appendix, dated October 1835, contains "additions to, and corrections of, the Catalogue of Species of American Naiades, with descriptions of new species and varieties of Fresh Water Shells."
