LIII, PART I (NO. 6). 14 92 DR L. F. SPATH ON I. INTRODUCTION. The Ammonoids described in the present paper were placed first of all, for study, in the hands of Mr J. M. WORDIE, whose departure, however, as geologist with Sir E. SHACKLETON'S Antarctic Expedition prevented the completion of the work. A preliminary list of identifica- tions by Mr WORDIE included a number of forms of "Schloenbachia" especially " S." inflata, J. Sowerby sp., this form alone being quoted from ten localities. Professor GREGORY, in his " Contributions to the Geology of Benguella," * referred to these identifications, and in his correlation-table classed the beds with " Schloenbachia injlata " as " Vraconnian," following the prevailing custom. It may be well, however, to remark here already that A. injlatus, J. Sowerby, will be shown to be an exclusively Albian, and not even uppermost Albian, form, and that there is no evidence of any Cenomanian admixture in the typically Albian fauna of the so-called " zone of A. injlatus" in Angola, so that the term Vraconnian is here rejected. Moreover, EENEVIER'S " Vraconnian" was meant for ^ost-inflata beds, and, in the writer's opinion, SOWERBY'S species is not represented at all in the Angola collection. - In March 1915 the collection was offered to the late G. 0. CRICK for examination and description. At about the same time Mr R. B. NEWTON studied the brachiopoda, pelecypoda, and gastropoda of Professor GREGORY'S collection, and his results, together with other palse- ontological and petrographical papers, were published in vol. li of the Transactions of the Royal Society of Edinburgh. + Mr NEWTON also briefly referred to the Ammonites, and followed CHOFFAT in considering the beds from which Professor GREGORY'S collection was obtained as of Vraconnian age, i.e. as " intermediate between the Albian and Cenomanian." I Mr CRICK had intended to publish his results at the same time, but owing to failing health he could not continue the work. The supervision of the fragmentary MS. was entrusted to the writer early in 1920, together with the task of naming the collection of Ammonoidea, which now are in the British Museum (Natural History), having been presented by Professor GREGORY in September 1916. The writer's thanks are due to Dr A. SMITH WOODWARD and to Dr F. A. BATHER, of the British Museum, for the opportunity of dealing with the collection ; also to Professor J. W. GREGORY for his ever-ready advice and help with the preparation of this paper, which now is offered as a belated contribution to the series of palaeontological papers that appeared in 1916. Especial acknowledgments are due to the Carnegie Trust for a very generous grant towards the cost of the illustrations. The writer soon discovered that he would have to study the collection quite independently of the work done by Messrs CRICK and WORDIE. Of 117 specimens in the collection, Mr CRICK'S notes only deal with fifteen ; and of these only the descriptions, but not the inter- pretations, of two new species have been accepted. Of the remaining specimens, a number bore provisional identifications by Mr WORDIE, acknowledged in each case under the specific descriptions, but these also had to be revised and largely altered. One specimen was described by Mr CRICK as " Mortoniceras delaruei, d'Orbigny sp.,"a form of the Middle Gault. Apart from this poorly preserved fragment, the identification of which, however, must be questioned, as will be seen under the specific descriptions, and, possibly, a second doubtful fragment, there is no evidence that a horizon below that of sub- zone VI6 of JACOB § or of Bed XI at Folkestone || is represented in this collection. Mr CRICK * Trans. Roy. Soc. Edin., vol. li, pt. iii, No. 13, 1916, pp. 498 et seq., 521. t Ib., Memoirs Nos. 14-17, 1916. I lb., No. 15, p. 562. § "Etudes Pal. et Strat. s. la partie moy. d. Ter.

CRETACEOUS AMMONOIDEA PROM ANGOLA. 93 himself, in his introductory remarks, stated that a preliminary examination of the specimens showed that they were chiefly referable to the genus " Mortoniceras," and that only one horizon appeared to be represented, viz. the Vraconnian, or zone of Mortoniceras rostratum, usually referred to in the literature dealing with West Africa as the zone of Schloenbachia injlata. Now, obviously, it was undesirable to continue to use in the customary indefinite manner the names of two such important Ammonites as SOWERBY'S A. rostratus and A. inflatus ; and a study of the English types of this group was essential. Since PICTET,* in 1861, erroneously stated that A. milletianus and A. inflatus could occur together (if very rarely), and on the other hand made A. inflatus range up, with A. curvatus and A. falcatus, beyond A. varians, into the Rhotomagian, the term A. inflatus has stood for one of the most heterogeneous assemblages of Ammonites ever known. What forms the records of A. inflatus, without figures, from many foreign, e.g. American, localities may include, it is impossible to say. On the other hand, SCHLUTER t stated already in 1876, what is practically confirmed at the present day, namely, that " no species of Cephalopoda occurs in the lowest Cenomanian [his zone of Pecten asper and Catopygus carinatus], that is found already in the beds below ; and that A.

The want of a complete and consistent list of the principal subdivisions of the mollusks having been experienced for some time, and such a list being at length imperatively needed for the arrangement of the collections of the Smithsonian Institution, the present arrangement has been compiled for that purpose. It must be considered simply as a provisional list, embracing the results of the most recent and approved researches into the systematic relations and anatomy of those animals, but from which innova- tions and peculiar views, affecting materially the classification, have been excluded.

  • Notes on the Carboniferous Cephalopoda
    Downloaded from http://pygs.lyellcollection.org/ by guest on October 1, 2021 257 some two miles inland, at an elevation of about 200 feet above the sea-level; and more recently have had a specimen given to me, said to have been found in Cornwall, but I am somewhat dubious about the accuracy of this locality. I am under the impression that Yermiculite Granite will be found in Yorkshire, especially in the northern division of the West Riding; and I trust our geological friends will carefully examine any granite boulders they may meet with in their excursions. It is only when the Granite is decomposed that the mineral can be properly separated from it; but even in situ, by careful observation, there will be no difficulty in detecting it. That these Granite boulders have travelled a long distance I am fully persuaded, and my belief is they have been transported to our shores in floating ice, very probably from Labrador. NOTES ON CARBONIFEROUS CEPHALOPODA. PART I. RECENT CEPHALOPODA. BY WILLIAM CASH, F.G.S. (PLATE XI.) THE true method of reasoning on natural objects and phenomena, is from that which is well known to that which is unknown; hence it follows, that a sound knowledge of the structure and relations of Fossil Animals can only be acquired by a careful study of the structure and relations of their living analogues. These and similar considerations have resulted in prefacing the proposed " Notes on Carboniferous Cepha• lopoda," with the following remarks on the structure, habits, distribution, and classification of their living repre• sentatives.

The Fossil Bluff Group of eastern Alexander Island was deposited in the fore-arc basin of an active magmatic arc, which formed the present-day Antarctic Peninsula. Cephalopods are common throughout the group. Ammonites and belemnites of several localities within the northern half of the outcrop are described, and previously described cephalopods are revised. Nine genera and seventeen species of ammonites (of which Raimondiceras alexandrensis and Blanfordiceras weaveri are new), and two genera and sixteen species of belemnites (including two new subgenera: Belemnopsis {Parabelemnopsis) and B. (Telobelemnopsis), and four new species: B. {Belemnopsis) launceloti, B. (T.) rymilli, B. (T.) bertrami and B. (T.) stephensoni) are described. This detailed study of the cephalopods indicates that the Fossil Bluff Group ranges in age from Kimmeridgian (late Jurassic) to at least Aptian (early Cretaceous), and enables seven ammonite biozones and three belemnite biozones (including two sub-biozones) to be erected within the group.

Key words: heteromorph ammonites; Lower Cretaceous; Silesian Unit; Reichraming Nappe. New records of heteromorph ammonites from the Silesian Unit of the Outer Western Carpathians (Czech Republic) are represented especially by small pyrite steinkerns with suture lines preserved. A lesser proportion of them belongs to representatives of the subfamily Bochianitidae from the Valanginian. Among the most interesting is Baculina rouyana dOrbigny. Another group consists pri­ marily of lower Barremian Leptoceratoidinae. In addition to commonly occurring species of Hamulin­ ites and Leptoceratoides, an Eoheteroceras assemblage is often found, represented partially by new ele­ ments. Heteromorphs from the Northern Calcareous Alps (Austria) come from marly Hauterivian limestones. Ptychoceras meyrati is present through most of the Hauterivian. Well­dated finds of less well­known species occur sporadically, such as Megacrioceras doublieri, Pseudomoutoniceras ex gr. annu­ lare, Acrioceras (Paraspinoceras) pulcherrimum, and A.

  • Information to Users
    INFORMATION TO USERS The most advanced technology has been used to photograph and reproduce this manuscript from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

  • Notes on the Carboniferous Cephalopoda
    Downloaded from http://pygs.lyellcollection.org/ by guest on October 1, 2021 257 some two miles inland, at an elevation of about 200 feet above the sea-level; and more recently have had a specimen given to me, said to have been found in Cornwall, but I am somewhat dubious about the accuracy of this locality. I am under the impression that Yermiculite Granite will be found in Yorkshire, especially in the northern division of the West Riding; and I trust our geological friends will carefully examine any granite boulders they may meet with in their excursions. It is only when the Granite is decomposed that the mineral can be properly separated from it; but even in situ, by careful observation, there will be no difficulty in detecting it. That these Granite boulders have travelled a long distance I am fully persuaded, and my belief is they have been transported to our shores in floating ice, very probably from Labrador. NOTES ON CARBONIFEROUS CEPHALOPODA. PART I. RECENT CEPHALOPODA. BY WILLIAM CASH, F.G.S. (PLATE XI.) THE true method of reasoning on natural objects and phenomena, is from that which is well known to that which is unknown; hence it follows, that a sound knowledge of the structure and relations of Fossil Animals can only be acquired by a careful study of the structure and relations of their living analogues. These and similar considerations have resulted in prefacing the proposed " Notes on Carboniferous Cepha• lopoda," with the following remarks on the structure, habits, distribution, and classification of their living repre• sentatives.
