CVlll PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



described and mostly figured in our Journal by Mr. W. H. Baily, 

 who observes that they bear a close affinity to the collection of fossils 

 from Southern India, so ably described by Prof. E. Forbes. Dr. P. C. 

 Sutherland has also given us some important information respecting the 

 geology of Natal, in a series of letters addressed to Sir R. Murchison. 

 Beds of sandstone and shale occur alternating with trap-rocks ; in 

 the former, several seams of coal have been found of no very good 

 quality, and which, from the appearances of the vegetable remains 

 in the shale, appear to belong to the Oolitic rather than to the true 

 Carboniferous formation. These facts are interesting as they cor- 

 roborate Mr. Bain's observations on the extension of the reptiliferous 

 and coal-bearing strata of the Karoo-series of the neighbouring re- 

 gions. Granite and other crystalline rocks also abound, and copper 

 in the form of malachite is not unfrequent. 



The Rev. W. B. Clarke has communicated to us some papers on 

 the geology of Australia. We have a paper on the occurrence of 

 obsidian bombs in the auriferous alluvium of New South Wales, and 

 another on the occurrence of fossil bones in the same deposit. After 

 comparing this latter fact with the occurrence of mammoth remains 

 in the auriferous alluvium of Berezof, in the Ural Mountains, Mr. 

 Clarke observes that their presence would seem to imply that the 

 gold in this deposit was collected at a comparatively recent date. 



Mr. H. Rosales has also communicated to us some fresh informa- 

 tion respecting the gold-fields of Ballarat, and of the Eureka and 

 Creswick Creeks, in Victoria, the alluvial deposit in which the gold is 

 now found, and the quartz-veins from which it has been derived. 

 Mr. Odernheimer has also forwarded, through Sir R. Murchison, 

 some new details respecting the geology of part of the Peel River 

 district. His attention had also been directed to the auriferous beds 

 and the gold-bearing quartz veins, and he has added some interesting 

 remarks on the formation of the gold, observing that he has no 

 doubt that it is derived from auriferous iron pyrites. 



PalcBontology. — Our active Assistant-Secretary, Mr. Jones, has 

 published in the ' Annals and Magazine of Natural History ' some 

 interesting notes on Pala30zoic bivalved Entomostraca. In these re- 

 marks he has described some species of Beyrichia from the Upper 

 Silurian limestones of Scandinavia. Drifted fragments of these lime- 

 stones occur abundantly in the diluvial sands and gravels of Mecklen- 

 burg, Brandenburg, and Pomerania. Mr. Jones having obtained frag- 

 ments of this rock from the gravels of Prussia and Silesia, proceeded 

 to examine their contents with a view of comparing the British forms 

 with those published by Kloden as portions of the carapace of small 

 Tiilobites, and of reviewing the nomenclature of the species and the 

 terminology of the subject. Mr. Jones describes the diiferent fossil 

 contents of five distinct fragments of limestone, of which one is from 

 near Berlin, and the others from the vicinity of Breslau. The result 

 of this examination was the discovery of no less than eight species of 

 Beyrichia, together with Cytheres, Lept(jena lata, the two latter 

 occurring in every fragment, Tentacvlites, and Encrinital remains. 

 Mr. Jones then proceeds to describe these species of Beyrichia, illus-
