GEOLOGICAL MEMOIRS. 



The second part of the work has reference to the organic remains 

 of the German Cretaceous system, and consists of a tabular list of 

 the fossils (pp. 84-277), synoptically arranged in zoological order, 

 with authorities and synonyms, stratigraphical places, and localities. 

 The localities of such of the enumerated species as occur out of Ger- 

 many are also given. The list comprises 1500 species, distributed 

 as follows : — 



Reptilia 4 Zoophyta 423 



Chelonia 1 Anthozoa 26 



Sauria 3 Bryozoa 283 



Pisces 87 Polythalamiaf 4 



Cycloidei 13 Amorphozoa 110 



Ctenoidei 6 Plants 115

At pages 279 et seq. reference is made to observations published 

 by the author and other naturalists on the Cretaceous formation in 

 various parts of Germany since the publication of the first part of 

 this work. The author again dwells on the fitness of the term 

 " Quadergebirge " in its application to this system in Germany, and 

 concludes with some further explanations of the use of the Tabular 

 List of Fossils, and with some remarks on the very high value that 

 attaches itself to the oryctographical works of Prof. Bronn (Index 

 Palaeontolog.) and M. A. d'Orbigny (Paleont. Francaise), to which 

 all writers treating of such a subject as the present must be neces- 

 sarily greatly indebted. 



The plates attached to the volume illustrate the stratification of 

 the Quader-formation, and forty-four fossils, of which the following 

 have not been previously figured : — 



Podocratus Diilmensis, Becks. Ammonites Neptuni, Gein. 

 Serpula tubseformis, Geinitz. Orbignyanus, Gein. 



* [Represented by the Cytheridce. The ten species grouped by the author's 

 friend Dr. Reuss under Cypridina (p. 98) belong to Cythere and Cythereis. —

f [Four only of the most common species of this group (Foraminifera) are 

 here enumerated ; the reader being referred to other works for an account of these 

 minute fossils, so abundant nearly everywhere in the Cretaceous series. — Trans.]
