Excerpt from Catalogue of the Type and Figured Specimens of Fossils, Minerals, Rocks and Ores in the Department of Geology, United States National Museum, Vol. 1: Fossil InvertebratesThe information relating to each entry is given in the following order (i) Catalogue number of the department registers, (2) name of species practically as written in the work cited, (3) kind of type, (4) formation, (5) locality, (6) author and place of publication, and (7) remarks on the present name if different from the one cited, or a cross reference when the same species appears in the catalogue under more than one name. Some notice is taken of synonymy, but as a rule only when this had been known previous to the making of this catalogue. In the case of remarks, these are always in brackets and signed by the author of the information, when not furnished by the present writer.No record is made of figures republished in text-books. In cases where a part of the material is lost, this fact is noted by the absence in the citation of the figures representing the missing material, no account being taken where all the specimens of an author are lost.An author's name in parenthesis indicates that the person cited did not use the genus or combination as given. It has not been thought necessary to give the author who first made the change as adopted in this catalogue.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
