FR. VON HAUER CONGERIAN STRATA. 25 



&c., on the western side of this barrier, are paralleled by Dr. Polle 

 with the basin of Rein ; and so also may be the lignitif erous fresh- 

 water strata of Liescha, near Privali (Carinthia), containing, accord- 

 ing- to M. Lipoid*, the same Gasteropodous species. Congeria;, 

 Mdanopsides, and other characteristic Inzersdorf forms have not 

 been found to occur in any of the localities just mentioned ; and the 

 relations of these deposits with respect to the Cerithian strata, con- 

 spicuously developed on the eastern side of the above-mentioned bar, 

 on the left banks of the Mur, are still to be ascertained. 



If the deposits just mentioned have nothing of the palaeonto- 

 logical type of the Congerian strata, it must appear the more sur- 

 prising to meet this type in the secluded and far more elevated 

 lignitiferous basin of Fohnsdorf, the first exact description of which 

 is clue to M. Kudernatschf. This geologist noticed the presence of 

 Congeria and Palvdina among the innumerable shells filling a bed 

 immediately overlying the lignite ; and Dr. Homes recognized one 

 of the species to be Congeria triangularis. 



The eastern portion of the Styrian tertiary region (Fiirstenfeld, 

 Feldbach, Gleichenberg, Kloeh, and the area comprised between 

 Padkersburg, Pettau, Marburg, and Mureck), as far as it has been 

 surveyed by Dr. Andrae j, is chiefly occupied by Cerithian strata, to 

 the exclusion of freshwater deposits of less ancient origin. Recent 

 observations from the immediately neighbouring portion of S.W. 

 Hungary have not come to my notice. On the banks of the Balaton 

 lake, near Tihany, our fauna appears again in full development. It 

 was the organic remains of this place (known under the vulgar name 

 of " Goats' hoofs ") that first induced the late M. Partsch to under- 

 take a scientific review of the genus Congeria. Prof. Zepharovich §, 

 who gave a detailed description of the peninsula of Tihany, found 

 there Congeria triangularis associated with Cardium plication, 

 Eichw., Melanopsis Dafouri, Fer., and Paludina Sadleriana, Partsch; 

 and above them a bed with Melanopsis Bouei, M. pygmcea, Partsch 

 (M. buccinoidea, Auct.), Planorbis, &c. 



Further southward the presence of the Inzersdorf strata is at 

 least indicated by the presence of Melanopsis Martiniana in the 

 Draun Valley (according to M. Sinnetinger |j), and by the Congeria 

 and Melanopsides (although rather incongruously associated with 

 genuine marine forms) enumerated in M. de Yukotinovic'.s " Cata- 

 logue of the organic remains from the mountains near Agram in 

 Croatia^." He also describes a limestone with Mi lania ami other 

 freshwater shells as occurring in thcMostuvinaMountains* ( ( Voatia), 

 leaving it in doubt, however, whether this is of merely local occur- 

 rence, or really belonging to the great freshwater lake of the Con- 

 gerian Period. 



In the south portion of the Hungarian basin, the environs of
