Book excerpt: Excerpt from Uintacrinus: Its Structure and Relations The occasion for this paper is the discovery of some remarkable specimens of Uintacrinus, which have disclosed a number of entirely new facts, not hitherto suspected, bearing upon its structure and relations. When Mr. F.A. Bather, of the British Museum, brought out his admirable morphological study of this remarkable Cretaceous Crinoid, it seemed as if he had left but little else for others to say on the subject. This would probably have remained true, but for the accession of fresh material and the discovery of new facts. Mr. Bather has since then prosecuted further researches in Great Britain and on the continent of Europe, with very interesting results bearing upon the occurrence and distribution of the genus in that part of the world. He has found that instead of being the rare form in the European Cretaceous which it was supposed to be, evidenced only by the unique specimen described by Professor Schlueter in 1878, Uintacrinus is one of the most abundant fossils at the typical locality in Westphalia, although occurring, so far as yet known, almost exclusively in the form of detached calyx plates and brachials. He was, however, so fortunate as to find at Recklinghausen a second well-preserved calyx of U.zvestalicns, about as good as the type specimen. In England he finds the detached plates very abundant in the Marsiipites beds of the White Chalk, closely associated with Boiirgueticrimis; and in some localities west of Margate Dr. Rowe has found them associated with Marsiipites.
