A well-preserved upper jaw of Anchitherium Aurelianense* lias been 

 lately found in the brown coal of Leiding (Lower Austria) ; also a tooth, 

 from the lower jaw, in the " marine sands " of Grossbach ; and another, 

 from the upper jaw, in the brackish " Tegel" of Nussdorf, near Vienna. 

 This species was long ago stated by the late P. Partsch to occur in the 

 Tertiary limestone of Brack on Leytha (frontier of Lower Austria) ; but 

 since that time it had not been met with in the Vienna basin ; now, how- 

 ever, it is proved to have lived during each of three mammalian periods, 

 the faunae of which are found in this basin. f 



M. Cornells de Groot, Chief Engineer and Superintendent of the Dutch 

 Colonial Mines in the East Indies, reports that the production of Tin in 

 Banka and Billiton (Blitong) has been — in the eight districts of Banka — 

 In 1857... 4609-037 Netherland tons, 1000 kilogrammes each. 



1858... 6028013

 1851)— 



In 1856... 209-839 Netherland tons, 1000 kilogrammes each.

The fossils found at Grand-Manil, near Gembloux, by M. Gosselet, and 

 referred by him to the Silurian period, but disputed by Messrs. Malaise, 

 De Koninck, and Dewalgue as true Devonian, have been admitted by M. 

 Dewalgue, after further researches by M. Malaise, to be Silurian. The 

 genus Trinucleus is represented by fragments of T. seticornis and T. BucTc- 

 landi, of Bohemia. A fragment appears to belong to T. ornatus. To the 

 genus Calymene are fragments of heads, pygidia, etc., nearly allied to 

 C. incerta, of Bohemia ; to the genus LitJias a head complete, analogous 

 to forms of the second fauna of that country. Other fragments belong 

 to the Silurian group of the genera Encrinurus, Chromus, Zethus, axid 

 Endymene. Lastly, pygidium of Homalonotus. This locality also con- 

 tains Graptolites, which are always regarded as characteristic of Silurian 

 deposits. 



M. Belval, Conservator of the Museum of Natural History at Brussels, 

 in classifying the collection of Echinoderms, has come upon a new species 

 belonging to the genus Encode of Agassiz, of the class of Scutellse. It is 

 near to the Encope Michelini of Agassiz, figured in pi. vi. fig. 9 and 10, of 

 his Monograph of the Scutellas, but very distinct from all other species 

 of this genus. This new species has received the name of Encojpe Ghies- 

 hrecMii, in honour of M. Ghiesbrecht, the traveller-naturalist, who found 

 it at Pernambuco, in Brazil, and presented it to the Brussels Museum. 

 E. Ghiesbrechtii is distinguished from E. Michelini by being much larger, 

 and not presenting that augmentation of height so remarkable in E. Mi- 

 chelini ; the apical rosette is not prominent; the poriferous zones are 

 narrower than the intermediate space.
