IV. — The Food of ä Siberian Rhinoceros. 
(Imp. Geol. Instit. Yienna, January 23, 1877.) 
Dr. St. J. Sckmalhausen lias microscopically examined the 
remnants of food contained in the cavities of the teeth of a North- 
Siberian Rhinoceros (Rh. antiquitatis ) whose remains are preserved 
in the museum of Irkutsk. These are remnants mostly of leaves, 
and of some stems, chiefly monocotyledonous. There are fraginents 
of grasses, and of small twigs of some woody plants, such as Picea 
(obovata ?) t Abies ( Siberica ?), Larix ( Siberica ?), Ephedra, sp., Salix, 
sp. (prevalent), and Betula ( fructicosa ?). All these plants still 
exist in high northem latitudes, and confirm Brandt’s supposition, 
that the Pachyderms of North Siberia lived in the regions where 
their remains, partly preserved by frost, are now found. — Count M. 
V. — The Species of Mastodon in Europe. 
Herr M. Vacek stated at the meeting of the Imp. Geol. Instit. 
Vienna, February 6, 1877, that of the seven species of Mastodon 
known to exist in the European Tertiaries, five have been ascertained 
to have lived within the region of the Austro-Hungarian empire. 
These are Mast. Borsoni , Mast, tapiroides, Mast, angustidens, Mast, 
longirostris, and Mast. Arvernensis. 
VI. — On an Ossiferous Cave in Thuringia. By Dr. K. Th. Liebe. 
(Imp. Geol. Instit. Yienna, February 20, 1877.) 
A small Bone Cave was discovered late in the autumn of 1874, 
in the Linden Valley, South of Gera in East Thuringia. The 
animals whose remains are found in this cave (probably a Hytena- 
den, of rare occurrence in Germany), arranged according to their 
relative frequency, are, Equus fossi/is, TLjana spelaa (nearly all the 
bones broken and evidently gnawn), Rhinoceros tichorhinus, Bos 
primigenius, Ursus spelteus, Felis spelcea, Cervus elaplius, Cerv. alces, 
Cerv. tarandus, Elephas primigenius, Alalcdaga geranus, Vulpes 
vulgaris, Canis, sp., Arctomys marmotta, Arvicola gregalis, Mas 
rattus, Cervus capreolus, Mustela, sp., Lepus, sp., Tetrao tetrix, 
Pandion haliaetus, and Charadrius, sp. The presence of Alalcdaga (a 
species of Gerboa), now living in the Steppes of extreme East 
Europe, and of Arvicola gregalis, an inhabitant of high Northern 
latitudes in Europe and Asia, are specially worthy of notice. The
