Nitecki Associate Curator, Fossil Invertebrates FEBRUARY 28, 1972 PUBLICATION 1141 Library of Congress Catalog Card Number: 70-1 72356 PRINTED IN THE UNITED STATES OF AMERICA BY FIELD MUSEUM PRESS TABLE OF CONTENTS PAGE Introduction 1 Catalogue of type and referred specimens 2 Catalogue of casts 272 References 298 vu INTRODUCTION The catalogue of fossil brachiopods lists the original fossil mate- rial and the artificial casts of type specimens housed in Field Museum of Natural History. The type brachiopods are predominantly of Middle and Upper Paleozoic age from the Upper Mississippi and Ohio River Valleys and from New York and the adjoining states. The extensive collection of fossils in Field Museum consists of the Walker Museum of Paleontology collection (prefixed UC) formerly at the University of Chicago, now on permanent loan to the Museum, and the Field Museum material (prefixed P or PE). In the catalogue, only holotypes are recognized as valid types; all other so-called primary or secondary types are listed as referred specimens. The name of the species and its authorship is entered as it was originally published; in addition, the publication date is always included. An attempt is made to note all subsequent sys- tematic changes. Systematic changes under the heading "Remarks" do not refer specifically to our specimen. The nomenclatural changes attributed to the Museum catalogue were probably made by Stuart Weller. The stratigraphic and geographic data are those of the orig- inal authors supplemented by the Museum catalogues. Specimens known to be lost or destroyed are listed as such ; however, type speci- mens not located at the present time are omitted. This work was supported in part by the National Science Foun- dation grant no. GB-7197. CATALOGUE OF TYPE AND REFERRED SPECIMENS Acambona ? osagensis (Swallow, 1860) Referred specimen: UC 12387.
