J.—On tHE ORBITOIDAL STRATA NEAR Auspitz, Moravia. By M. 
A. Rzenak. [ Proceed. Imp. Geol. Instit. Vienna, July 31, 
1882.] (Communicated by Count Marscuatt, F.C.G.S., etc.) 
HE prevailing deposits are soft sandstones and blue marls, dis- 
tinctly stratified, and resting on menilitic shales. The marls 
include in one locality remains of Meletia, and in another some few 
Foraminifera, probably referable to a late Oligocene horizon (“'Ton- 
grian-Aquitanian”’). A deposit lithologically and chronologically 
distinct from the “soft sandstones” appears on the Steinberg and on 
the south slope of the Haidenberg. It is a highly calcareous sand- 
stone, with intermediate conglomerates, including fragments of 
erystalline, massive, and schistose rocks, and with occasional layers 
of green clay containing Foraminifera, on the whole of older Oligo- 
cene type. A fine-grained bed of the sandstone contains Foramini- 
fera, including a large Dentalina, possibly Denialina Herculea, 
Gtimbel, a “Nummulitic” form. Other organic remains in the 
sandstone are fragments of Shells, Corals, Polyzoa, and rarely teeth 
of Squalide. Nummulite-like shells are very frequent in some strata. 
These lenticular shells, beset with small tubercules, are Orbitoides. 
They are identical with, or, at least, very near to Orbitoides aspera, 
Giimbel; and equal in size to those from the Buda Marls, though 
smaller than the Bavarian specimens. These Orbitoidal beds are 
evidently the most ancient member of the Tertiaries in the Auspitz 
district, being coeval, isotopic, and partly isopic, with those of 
Kirchberg, in Lower Austria, and of Stokerau, north of Vienna. 
They are of the same age as the upper strata of Priabona, and 
Hoffmann’s “ Orbitoidal Horizon ” in Hungary. 
The Foraminiferal clay of Rikolschiz is, in some respects, allied 
to that of the Hungarian Middle Oligocene (Clavulina Szaboi beds). 
Their Foraminiferal fauna, especially the Orbitoides, imparts to them 
more of the “ Alpine” than of the “Carpathian” types. Possibly, 
together with the analogous Hungarian deposits, they may constitute 
a special geological province, connecting the ‘‘ Alpine” with the 
“ Carpathian Sandstone Zone.” 
II.—Guactat Sections ar York, AND THEIR RELATION TO OTHER 
Deposits. By J. Epmunp Crarx. [Geol. and Polytechnic Soc. 
W. Riding of Yorks, vol. vii. pp. 421-489. | 
[* this paper details are given of a number of sections of Glacial 
and Alluvial deposits in the neighbourhood of York. The 
occurrence of Ursus speleus (identified by Mr. W. Davies, F.G.S.) in 
the valley gravel appears to be the first record of a carnivorous mam- 
mal in this deposit near York. Mr. Clark mentions that in the deposits 
at Overton, Mammoth, Hippopotamus, etc., have been found.
