the north, but with many undulations and
fractures, and in them the following fossils
are found, as identified byM. Zeuschner: —
AmmonitesWalcotti, A. Bucklandi, A. an-
nularis. Nautilus acutus (V. Buch), Be-
lemnites digitalis, Terebratula biplicatay
Spirifer TFalcotti, S. rosti'atus, with Ap-
tychi, Cidarites, Pentacrinites, and some
remains of ichthyolites. This group of
fossils leaves no doubt,
stones containing them

Tatra, there are other limestones in a
more or less crystalline state, w^hich,
compressed by high inclination into a
small horizontal distance, are difficult of
access on account of dense woods and their
rugged outline. To these I cannot pretend
to assign a precise age. On their flank,
and particularly on the left bank of the
Biala Dujanec, where that stream issues
from the gorge of Zagopane, they are un-
conformably and irregularly covered by a
band of nummulitic limestone (/"), which
dips off at an angle of 35° to 40° and
passes under a portion of certain schists,
sandstones and impure limestones .g),
which occupy a portion of the hilly tract
extending northwards to the valley of Neu-
markt. This nummulite limestone is thick-
bedded, of grey colour, in part a coarse cal-
careous grit, and even a small conglomerate
made up of fragments of the underlying
limestones, and is much charged with mag-
nesia. It contains nummulites throughout
a thickness of upwards of 100 feet, but most
abundantly in the upper beds. Among
these, besides the Nummulina globulus,
Leym. ?, there is the large species N.
planospira ?, so common in the Alps and
elsewhere ; and these typical fossils are
also, as in many other regions cited, asso-
ciated with certain pectens, ostreae, &c.,
•auoqisanin and large echinoderms, &c. In short, the
P3j3?tv fQggji assemblage of genera and forms is
so precisely the same as that seen in the
%■% supracretaceous nummulitic rocks of the
I ;f Alps, that no doubt can exist as to the age
