STUE TERTIABIES OF SCLAVONIA. 27 



The Congeria-beds form the remaining greater portion of the 

 Tertiary hilly land. They present exactly the same sections as those 

 so well known in the Yienna Basin ; but the contained fossils are 

 somewhat different, as will be seen hereafter, — a peculiarity which 

 was first noticed by Herr Ludwig v. Farkas-Yukotinovic*. 



The Belvedere beds are also developed in the same degree as in 

 the Yienna Basin — the Belvedere Schotter being of very local 

 occurrence ; whilst, on the other hand, the Belvedere sand covers 

 the whole district of the Congeria-beds with a thickness of from 4 

 to 10 fathoms, and appears as a sandy Loess-like loam. 



The next older stratum, the '' Freshwater Limestone " of the 

 Yienna Basin, is represented just as at Moosbrunn. It may be seen 

 close to St. Leonard's Church, near ^eu-Gradiska. First there crops 

 out from beneath the Loess-like sand a sandy greenish " Tegel," 

 containing Valvata pisdndlis, Lam., very abundantly ; then follows 

 a stratum of whitish freshwater limestone, in beds 3 to 4 inches 

 thick, and containing small specimens of Congeria, species of Helix, 

 Planorhis, and Melanopsis, in casts both solid and hollow. Beneath 

 these occur beds of soft, almost marly freshwater limestone alter- 

 nating with yellow loamy sand and dark blue shaly "Tegel," and con- 

 taining fossils belonging to the following species, as determined by 

 Herr V. Frauenfeld : — Valvata jpiscinalis, Jjam., Melanojosis Esperi, Fer., 

 Paludina concinna, Sow., P. tentaculata, L., P. Sadleriana, Partsch, 

 NeritiTia transversalis, Mhlf., and a ribbed species of Anodonta. 



Underneath this last bed is the " Tegel," containing a bed of 

 Lignite : the thickness of the former under the Lignite is unknown, 

 but it must be very considerable. The stratification, as seen along 

 the banks of the streams, is very much disturbed. 



A freshwater limestone t occurs at the spring in the forest in the 

 Drinoosta-Thal, north-west from Kutina. It contains Paludina 

 Sadleriana, Partsch, and P. concinna, Sow. 



In the drainage- area of the Drsive, the Congeria-beds crop out. 

 In a narrow pass near Borova a bed of sand may be seen dipping 

 slightly towards the south, and upon the tops of the hills there is 

 one, from two to three feet thick, containing sandstone concre- 

 tions ; the grains of sand being cemented together by carbonate of 

 lime, derived, probably, from the shells of Cardium, several of which 

 are contained in each concretion of less than one foot in diameter. 

 The most abundant species is Cardium Haueri, Homes ; it is asso- 

 ciated with C. Hungaricum, Homes, and another Cardium, (unde- 

 terminable), occurring only in casts ; also small specimens of Con- 

 geria and Paludina tentaculata, Lam., are found. 



The Loess of the older Diluvium was only observed at some points 

 along the course of the Save, on the boundary of the plain towards 

 the Tertiary hilly land. 



The surface -rock of the plain of the Save and Drave belongs to 

 the terrace Diluvium. [H. M. J.]
