STUB, AND WOLF AUSTRIAN TERTIABIES. 31 



Mactra Podolica, Eichw., Donax lucida, Eichw., Cardium Vindo-> 

 bonense, Lam., and a single badly-preserved specimen of Cerithium 

 pictam, East. 



It may be inferred from these sections, that in the locality in 

 question the yellow sands, sandstones, and calcareous porose sand- 

 stones, corresponding to the Cerithian strata of the Vienna basin, 

 are overlaid by strata of greenish clay and felspathic sandstones with 

 Congerice. The occurrences here described seem to be strictly local. 

 In the vicinity the yellow (probably Cerithian) sands are immediately 

 overlaid by diluvial detritus, so that the presence of Congerice may 

 . be supposed to indicate the former existence of a local freshwater 

 current. 



2. Near Sereth (Buhtowina). [Stur.] — A hill of grey sandstone, 

 in nearly horizontal layers, with intercalated marls, opened by 

 quarries, gave the following organic remains (more frequent in the 

 marls than in the sandstone itself) : — Murex sublavatus, Bast. (?), 

 Cerithium mitrale, Eichw. var., Rissoa inflata, Andrz., 11. angulata, 

 Eichw., Bulla, sp. (B. Pupa, Eichw. ?), Vermetus intortus, Lam., 

 and ErvilUa Podolica, Eichw., which, although but indifferently pre- 

 served, indicate a fauna corresponding to that of the Cerithian strata 

 in the Vienna basin. 



3. Between Netzendorf and Sjpeising (about three English miles 

 W.S. W. of Vienna). [H.Wolf.] — The Wiener Berg, running south of 

 Vienna in an E.-W. direction, shows exclusively Congerian strata in 

 its central portion near Inzersdorf. In its westerly continuation 

 (hills of Meidling and in or near Schonbrunn) Cerithian strata, 

 dipping, at low angles and with various undulations, eastward 

 beneath the Congerian strata, make their appearance. A railroad- 

 section has laid bare Congerian strata, only a few feet thick, while 

 about 4200 feet eastward their thickness exceeds 70 feet. These 

 strata, dipping slightly eastward, with various undulations, are, in 

 descending order, as follows : — 



1. Boiled fragments of Vienna Sandstone (1-2 feet); 2. Undu- 

 lated seam of yellow sands (3 inches); 3. Blue plastic "tegel" 

 (2 feet) ; 4. Undulated yellow clay (4 inches) ; 5. Bluish-grey 

 sandy "tegel," with Cardium conjungens in its upper part, and with 

 Congeria Partschi, Cz., and large nodides of calcareous marls in- 

 cluding plant-remains, in its lower portion (5-0 feet) ; <>. Sand of 

 minutely triturated Shells, with an intercalated band of small frag- 

 ments of Vienna Sandstone (16 inches); 7. Sandstone, "with Congeria 

 spathidata, Bartsch ; 8. Grey sands (1 foot) ; 0. Yellow sands, with 

 triturated Shells (6 inches); 10. Grey sands (4 feet); 11. Gravel 

 of Vienna Sandstone, not yet sunk through. At two other places 

 this gravel is exposed to the thickness of above feet, overlaid by 

 nearly 1 foot of sands, in an undulated layer, dipping eastward. 



North of the west end of Hetzendorf, the railroad has cut 

 through 1 foot of soil, 1 inch of sandstone, and IS feet of •• tegel," 

 which has been penetrated by a pit as far as the Cerithian Bandstone 

 immediately under it. The portion next to the sandstone was found 

 to contain Cardium Vindobonense, Bartsch, MytilvA carinalus, Br.,
