disks, about ^j inch ia diameter and y^- inch thick, with a smooth sur- 

 face, and composed of a spiral of three or four nearly equal convolu- 

 tions, divided into chambers by curved septa. The minute tubulation 

 of the shell is perfectly preserved ; and the canal-system of the septa can 

 also be determined. H. A. N. 



Brauns, Dr. D. Der obere Jura im nordwestlichen Deutschland, 

 von der oberen Grenze der Ornatenschichten bis zur Wealdbildung, 

 mit besonderer Beriicksichtigung seiner Molluskenfauna. [Upper 

 Oolites of N. W. Germany.] 8vo. Braunschweig. Pp. 43i, with 

 3 plates of fossils. 

 On the same plan as the former works on the L. and M. Jura. The 

 ground covered by the present volume extends from the Coral Rag to 

 the Purbecks. The J^. German U. Oolites are divided into the follow- 

 ing sections : — 1, Perarmatus-heds ; 2, Cidaris florigemma beds, or 

 Coralliue Oolite ; 3, L. Kimmeridge ; 4, M. Kimmeridge ; 5, U. Kim- 

 meridge ; 6, Ammomtes glgas beds ; 7, Purbecks. Sections and leading 

 fossils, with their places of occurrence are given under each head. The 

 second part consists of a critical history of all the Mollusca known 

 from these beds. The chief feature of this palaeontological part is the 

 position taken up, that only zoological characters are regarded in the 

 definition of species; hence the latter are very comprehensive. The 

 result is a total of 282 Mollusca in the N.W. German U. Jurassics, of 

 which only 10 pass up from the M. Jurassic (U. Lias to M. Oolite). 

 In the author's L. Jurassic (=L. and M. Lias) were described 215 

 species, and in the M. Jurassic 196 species. The thickness of these 

 tJ. Jurassic beds is about 350 metres. 



The following new species are described and figured : — OervilUa 

 Os7iabracke)isis,lLrom U. Kimmeridge of Lauenstein, and Turbo Witteanus, 

 from the L. Kimmeridge of Ahlem. E. B. T.

 Purbeck Beds and the Lias, and from Permian, Carboniferous and 

 Devonian rocks. W. W.
