8TTJK— TRRTIARIES OF SCLAVONIA. 25 



crystalline rocks are here surrounded by Congeria-beds ; . but the 

 Leithakalk is seen beneath them in a deep valley on the northern or 

 Nasic side, and also occasionally on the south side, east of GrediBtje. 

 In the road upon the Bektes side, near Gredistje, there crops out a 

 loosely coherent Nullipore-limestone, extremely like that of Yucin, 

 containing Pecten latissimus, Brocc, and Ostrea digitalina, also Am- 

 phisteginaHaueri, Orb., A. Tnammillata, Orb., andHeterostegina costata, 

 Orb., and the following Bryozoa, determined by Dr. Stoliczka : — 



Hornera hippolyta, Befr. Salicornia marginata, Goldf. (8. crassa, 



Idmonea foraminosa, Beuss. Busk). 



tenuisulca, Beuss. Eetepora cellulosa, Lam. 



Griebeli, Stol. Cellepora globularis, Bronn. 



Myriozoum truncatum, Lam. Eschara bipunctata, Beuss. 



monilifera, Milne-Edw. 



This formation disappears in a southerly direction, and therefore 

 immediately under the highly inclined Congeria-beds. 



A series of beds of particular interest was found in an almost 

 isolated position, surrounded by crystalline rocks, partly upon the 

 heights of Gradac, and westward from them, and partly in a small 

 basin lying northward from Gredistje. The prevailing rocks on the 

 south-western border of the basin were clay and sandstone, the 

 former containing many badly preserved remains of Eish. Three 

 seams of very good brown-coal were also found in it*, dipping very 

 fast towards the south. They are separated only by very thin beds 

 containing Planorhis, sp., and together they attain a thickness of 

 from one and a half to two fathoms. Eastwards they are soon cut 

 off by the crystalline rocks, and westwards they very shortly dis- 

 appear under the Congeria-beds. Interstratified with the coal, and 

 filling up the rest of the basin, are tuff and conglomerate, containing 

 pebbles of trachyte and, more rarely, of basalt. 



Further westward, near Kutjevo, the coal-bearing clay, shale, and 

 sandstone, closely corresponding with the E-adaboj beds, tower up to 

 a considerable hill from out of the Congeria-beds, and the author 

 was informed of an outcrop of coal there. Unfortunately only one 

 specimen of Melania Escheri, Brongn., that is so abundant in the 

 Cerithium-beds (Gaunersdorf) of the Vienna Basin, has been observed 

 here. 



Southern slope of the Orljava-Gehirge, near Velika. — The Older 

 Neogene strata crop out in this district from under the Congeria- 

 beds, the only beds seen being the Leithakalk and those beneath it ; 

 the younger marl and the beds of Kutjevo not being observed. Near 

 Yelika the marine Neogene strata, corresponding with the "Tegel" 

 of Baden or the beds of Rogolje and Benkovac (see above), were ob- 

 served. The lowest bed is a coarse sand, here and there of a brick- 

 red colour ; upon it lies a white, light, friable marl, like that in the 

 ravine of Brussovac ; then comes the Leithakalk. 



The bed of the sea of the Older Neogene epoch must therefore 

 have been very undulating, and here and there the Trias shale must
