Preserved in slabs of impure coal, they were stated by Moodie to have come from "the Coal Measures of Washington County Kansas," and are, so entered in the records of the National Museum. But the sediments of Washington County Kansas are of Cretaceous and Permian age and contain no "Coal ; Through the courtesy of Drs. Nicholas Hotton, III and G. A. Cooper of the U. S. National Museum, the history of the specimens has been traced. It was part of a collection assembled by Prof. Gustave Hambach of St. Louis which was purchased by that Museum in 1909. It mainly consisted of fossil echinoderms, but also included a few other animal and plant fossils which Professor Hambach had picked up in the course of his search for echinoderm materials. As far as known, he never visited Washington County, Kansas, but did work in Washington County, Arkansas and, in fact, described echinoderms of the ge
