Excerpt from A Descriptive Catalogue, Vol. 1: Of the Naiades, or Pearly Fresh-Water MusselsThis work was begun immediately after the publication of my Synopsis of the Naiades in 1900 and was completed, substantially as it now appears, in the latter part of 1901. It was prepared in anticipation of an immediate publication with illustrations of all the species. But owing to the failure of that expectation and my removal to Florida in 1902, the mss. Was laid aside and nothing further done upon it until recently.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
