A M-ell-preserved upper jaw of AncliHher'mm Aurelianense* has 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 Xussdorf, near Vienna. 
This species was long ago stated by the late P. Partsch to occur in the 
Tertiary limestone of Bruck 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. Cornelis de Groot, Chief Engineer and Superintendent of the Dutch 
Colonial Minos in the East Indies, reports that the production of Tin in 
Banka and Biiliton (BHtong) has been — in the eight districts of Banka — 
In 1857... 4609-037 Xetherland tons, 1000 kilogrammes each. 
1858... 6028013 
1859...5686-189 
I860.. .5175-621 
1861... 5406-500 
In Blitong (where M. de Groot first discovered and worked tin-ores in 
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. Malai.se, 
De Koninck, and Dewalgue as true Devonian, have been admitted by M. 
Devvalgue, after further researches by M. Malaise, to be Silurian. The 
genus Trinucleus is represented by fragments of T. seticornis and T. Buck- 
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. iiicerta, of Bohemia ; to the genus Lithas 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, Zethns, and 
Endymene. Lastly, pygidium of Homalonotas. 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 Encope of Agassiz, of the class of Scutella?. 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 Encope Ghics- 
hrechtii, in honour of M. Ghiesbrecht, the traveller-naturalise, who found 
it at Pernambuco, in Brazil, and presented it to the Brussels Museum. 
E. Ghiesbrechtii is distinguished froi^i E. MicheUni 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.
