V. — Fossils from the Coal-Measures of Bohemia. By J). Stur 

 and A. Fritsch. Imp. Geol. Inst. Vienna, Meeting Dec. 5, 1876. 

 [Communicated by Count Marschall, F.C.G.S.] 



1. Three species of fossil Plants were latel}^ found for the first 

 time between the first and second Coal-seams of the Kladno-Schlau 

 Basin, namely, SpJienopteris irregularis, St. (together with Astero- 

 carpus Wolji, Stur, in the same state of preservation as in the roof of 

 the upper Coal-bed of Radnitz) ; Alethopferis Serlii, Brongn. (only the 

 apex of a frond) ; and Pexopteris elegans, Germ, (a large fragment 

 of a frond, agreeing in minute details with a specimen from Wettin 

 in Saxony). 



2. Animal-remains have only been met with in one subdivision 

 (Radnitz Beds) of the Centro-Bohemian Carboniferous Formation. 

 They all belong to essentially Terrestrial Animals — Crustaceans, 

 Arachnids, and Insects ; and are distributed thus : — 



In the roof of the upper Radnitz Coal : Lepidoderma Imliofi, 

 Reuss ; Xyloryctes planus (borings). 



In the upper Radnitz Coal-seam : Gampsonyx, sp. (in laminated 

 coal). 



In the roof of the lower Radnitz Coal : Palaranea horassifolice, 

 Fr. ; CyclopJithahnus senior [Microlahis Sternhei-gi) , Covda ; Xyloryctes 

 septarius (borings). 



In the floor of the Radnitz Beds : G amp sony elms parallelus, Fr. ; 

 Acridites priscus, Andree. 



Excellent specimens of all these forms are preserved in the newly 

 established Geological Museum of Prague. 



VI. — The Distribution of the Cephalopoda in the Upper Chalk 

 OF North Germany. [Verbreitung der Cephalopoden in 

 der oberen Kreide Nord - deutschlands, von Clemens 

 ScHLiiTER.] (Zeitschrift der Deutschen geologischen Gesell- 

 schaft. Band xxviii. heft 3.) 



THIS Memoir by Herrn Clemens Schliiter constitutes a kind of sup- 

 plement to his work " Cephalopoden der oberen deutschen Kreide." 



The Upper Cretaceous beds of North Germany are subdivided into 

 the following zones in ascending order, viz. : — 

 Zone of Fecten asper. 



„ Amm. varians. 



,, Amm. RhothomMgensis, 



,., Actinocamax pleniis: 



,, Inoceramus labiatus. 



,, Inoceramus Brongniarti. 



„ Heteroceras Eeussiamim. 



A brief sketch of the geographical extent, and equivalents in 

 France or England when such exist, together with a list of the 

 Cephalopoda obtained, is given under each of these headings; whilst 

 appended will be found a table showing the respective vertical 

 ranges of the 155 species of Cephalopods in the Chalk of North 

 Germany; or, rather, their respective positions in the vertical series: 

 for the most prominent fact revealed in this table is the limitation of 

 these several species to the different hoi-izons, only a few being 

 common to two or sometimes three consecutive zones. B.B.W. 



Zone of Inoceramus Cuvieri. 

 „ Amm. MargcB. 

 ,, Scajohites binodosiis. 

 ,, Becksia Soekelandi. 

 ,, Amm. Ccesfeldiensis. 

 „ Heteroceras polyplocum.
