tritus of the primary slaty rocks on which tiiey rest at high angles of 

 inclination, and rise into the lofty mountain of the lladiberg. 



b. Shale and sandstone with coal. There are various beds of lignite 

 near Eibeswald, one of which is deposited on the grits of the Radl- 

 berg. At Scheineck, where the coal is extensively worked for use, it 

 contains bones of anthracotheria, and in the shale are found gyro- 

 gonites (Chara tiiberculata of the Isle of Wight), many flattened 

 stems of arundinaceous plants, cypris, shells of paludinse, scales of 

 fish, &c. From liie organic remains and position of the strata it is 

 presumed by the authors that this coal is of about the same age as 

 that of Cadibuona in Piedmont. 



c. Blue marly shale, sand, &c. The carboniferous strata are sur- 

 mounted by dark-coloured marls inclosing well preserved shells, 

 many of which are identical with species found in the London clay 

 and Calcaire grossier, amongst which are Lutraria oblata, Lucina 

 mutabilis and renulata, Venus vetula, Cerithium thiara. Bulla cylin- 

 drica, &c.&c. 



d. Conglomerate, with micaceo-calcareous sand and millstone con- 

 glomerate. This group is of very great development and occupies 

 all the hilly region of the Sausal. 



e. Coralline limestone and marl. The preceding group is seen, both 

 atEhrenhausen and Wildon on the Mur, to pass under a hard, mottled, 

 coralline limestone of a yellowish white colour, which at the latter 

 place forms a caj) several hundred feet thick in beds nearly hori- 

 zontal. The fossils seem to be of the age of the English Crag 

 and middle Sub-apennine formations, and include many corals of the 

 genera Astrea and Flustra, Crustacea, Balanus crassus, Conus Al- 

 drovandi, Pecten infumatus, Pholas, Fistulana, &c. The authors com- 

 pare this coralline limestone witli the tertiary marble of Possagno 

 near Bassano, and they also observe that it far exceeds in magnitude 

 the secondary coral rag of England. 



f. White and blue marl, calcareous grit, white marlstone, and con- 

 cretionary white limestone. The Mur in its easterly course from 

 Ehrenhausen, exposes all the members of this and the following group, 

 although some of them are still better seen in transverse sections to 

 the .south. At Santa Egida concretionary, white limestone alternating 

 with marls, contains Pecten pleuronectes, Ostraea beliovicina, Sca- 

 laria, Cypraea, &c. and in the Zirknitz-thal, Echinanthus marginatus 

 with gigantic oysters and pectcns. At St. Kunegund and Morgruben 

 the white; marls graduate into a compact building stone undistin- 

 guishable from the dunch or lowest chalk of Cambridgeshire, Near 

 Mureck on the right bank of the Mur, the upper portion of this group 

 is remarkable by containing a very white concretionary limestone 

 made up of small tubular and concentric layers, several varieties of 

 which, occurring in other parts of this tertiary series, very much re- 

 semble coiuTctioiis in the magnesian limestone of England. 



g. Calcareous sands and pebble beds, calcareous grits and oolitic 

 limestone. These form the superior and youngest stratified deposits 

 of the country. At Iladkersburg, where the section terminates and 

 tlie hills sink into tlie plains of Hungary, tlie sands, marls, and grits 



are
