264 Dr Boue on the Geography and Geology of 



The composition of the northern Servian tertiary basin is 

 identical with that of Southern Hungary and the Bannat. The 

 inferior rocks are argillaceous marls, or molasse with sandy 

 marls, then sands and sandy marls, with some conglomerate 

 and calcareous beds containing fossils, such as Cerithium, Car- 

 dium, Venus, Concheria, Trochus, &c. I may mention as ex- 

 amples, the sections at Vischnitza, Grotzka, E. and S. of Bel- 

 grade, Kakovitza, Raila, Schabari, Kragojevacz. Coralline 

 limestones, like those of Syrmia and the Leithagebirge near 

 Vienna, are also to be met with, particularly in those parts 

 bordering on the Danube, as at Vischnitza, Belgrade, and south 

 of Sau. In the upper part of the basins, where the influx of 

 fresh water must have been greater than elsewhere, one some- 

 times observes whitish or greyish marls containing Cypris, 

 Planorbis* Paludina, Lymnea, and Concheria (C. spathulata), 

 as at Relnitza, and on the shores of the Mutnitschka-rieka, 

 near the monastery of Svetapetka, W. of Parakin-Palanka. 

 To the SW. of Kragojevacz I also found marls with Cy- 

 pris, and in the sandy marl a whitish coarse limestone, with 

 many impressions of the Concheria triangular is (Partsch). 

 Lignites are met with near Semendria and Miliova, at which 

 latter place Planorbes occur. 



The Kossova-Pristina basin is situated pretty high, and is 

 evidently the site of an old lake, of which the bottom is now 

 alluvial, and the sides are covered here and there with marls 

 and a conglomerate having a calcareous cement like that of 

 many fresh-water limestones. 



The Kostendil) Dubnicza, Radomir, and Dzumaa basins con- 

 tain only molasse and marls. These arenaceous rocks form 

 considerable ridges between Dubnicza and the Radomir and 

 Kostendil plains. One of the ridges between Kosnitza and 

 Verbonitz surrounds or covers old compact limestone hills, 

 and the Strymon flows through a rent running N S. in this 

 molasse, from Kosnitza to the confluence of the Dubnicza river 

 with the Strymon. 



The molasse is inclined to the S.E., and some coarse con- 

 glomerates are seen on the sienitic rocks near Kosnitza, and 

 between that place and Shetirtza. These last are partly hori-
