Older rocks of the Pozegan Mountains. — Besides some crystalline 

 rocks described by the author in a former paper, these include clay- 

 slate (probably of Carboniferous age), and an overljing felspar- 

 porphyry and tuff which contain melaphyr in veins and in bedded 

 masses ; and also a formation, composed chiefly of a coarse conglome- 

 rate, which forms the greater part of this range of mountains. 



From Maksimov-hrast, in the Tissovacer Yalley, upon the southern 

 slope of the Pozegan Mountains, and where the author first examined 

 these strata, proceeding towards the west, it can be seen that through- 

 out the whole of this district there prevails a conglomerate, composed 

 of pebbles of various kinds, and only held together by a very feeble 

 argillaceous cement. Under this stratum, besides those already 

 mentioned, there exist the following formations, in ascending order : — 

 1st, A very fine-grained, laminated, shelly limestone. 

 2nd, A red limestone, resembling the Triassic limestone of 



Markovac, E. of Daruvar. 

 3rd, A conglomerate formed of pebbles of a dark-grey clay- 

 slate. 

 4th, and uppermost, a conglomerate composed of pebbles of a 

 fine-grained sandstone resembling the Yienna Sandstone, or 

 the Lias Sandstone of the Alps or the Fiinfkirchen Mountains. 

 The appearance of this stratum was quite new to the author, and, 

 from the absence of fossils, the determination of its age was some- 

 what difficult. He found the Leithakalk overlying it E. of Bacindol, 

 and the " white marl " N. of that place. South of Pozeg he saw the 

 Pozeg conglomerate, the felspar-porphyry and tuff, and the under- 

 lying slate. Above the Pozeg conglomerate, between Maticevic and 

 Pavlovce, N. of Neu-Kapela, there occur, first, Leithakalk, composed 

 chiefly of NuUipore concretions, then beds of limestone with masses 

 of Cerithium ruhiginosum, Eichw., and (7. pictum, Bast., upon which 

 follows the " white marl." 



The age of this conglomerate is therefore somewhere between that 

 of the Leithakalk, on the one hand, and that of the felsit-tuff on the 

 other. The hope yet remained that fossil plants might be found in 

 the coal-bed contained in it. The proprietor, Herr J. D. Popovic, 

 reports that this bed dips S.E. Its thickness is about two fathoms*; 

 but a thinning-out was observed at the spot where the bed was 

 won by a new shaft, at the depth of 17 fathoms, the older ones, as 

 well as the levels, being inaccessible, so that it appeared there to be 

 * The measurements are in Austrian fathoms, feet, &c..
