On the Guotocy of Roumerta. By Prof. F. von Hocusrerrer. 
[Proc. Imp. Geol. Inst. Vienna, November 16, 1869.] 
Prorsessor Hocusterrer has accompanied M. W. Pressel on a tour 
through part of European Turkey. The region explored by him 
occupies an area of about 800 Austrian square miles, stretching 
through about 80 miles, from the river Morawa to the Bosphorus, 
with an average width of 10 miles, from the Balkan to the Rhodopi. 
He distinguishes the following districts :— 
1. The Cretaceous plateau between Rustschuk and Varna.—The 
mass of plateaux and flattened mountains, with a maximum altitude 
of 1200 feet above the sea-level, from the northern base of the 
Balkan, near Schumla and Razgrad, to Rustschuk on the Danube, 
is composed of a system of nearly horizontally stratified calcareous 
marls, green sandstones, and Oolitic limestones. Abundant remains 
of Cephalopoda (Belemnites, Ammonites, Baculites, Hamites, &c.) 
found in the quarries of Schendeinschick, in a rock exactly resem- 
bling the marls of the Plinerkalk, show that these deposits belong to 
the Cretaceous series. These sub-Balkanian Cretaceous rocks have 
a northern European type, as has already been remarked by Prof. 
Peters with regard to the contemporaneous deposits in the Dobrud- 
scha. Well-marked Nummulitic Limestones (described by Capt. 
Spratt in the Quart. Journ. Geol. Soc. vol. xiii.) occur round Varna, 
and Sarmatian deposits cover a very limited space in the immediate 
vicinity of that place. 
2. The Byzantine peninsula is composed of Devonian strata and 
of Tertiary Limestones. The latter are of Eocene age at Jarim 
Burgas, and of Neogene date at Makrikioi. The range of Tscha- 
taldsche rises like an island out of these Tertiaries. Eruptive rocks 
of Trachytic, Dioritic, and Andesitic nature are conspicuously de- 
veloped on the shores of the Bosphorus. 
3. The Lower Maritza or Adrianople basin.—This is bounded 
on the north by a range formed of Eocene Limestone, resting im- 
mediately on gneiss, near Sarai, Visa, Kirklisi, &c. The interior of 
the basin, which is furrowed by innumerable watercourses, is filled 
up with Newer Tertiary and diluvial freshwater deposits. Prof. 
Hochstetter nowhere met with traces of Neogene marine deposits 
south of the Balkan. 
4. The region of the river Tundscha.—Between Adrianople and
