In the Gosau district itself these beds rest upon Triassic 

 rocks, but near Salzburg they lie upon the Gault, and 

 must, therefore, be of Upper Cretaceous age. It is not 

 possible to make a direct comparison of the Gosau beds 

 with those to the north, but the fauna is very like that of 

 the Corbieres in the South of France. Toucas there 

 recognises two Hippurite zones, the first containing Hipp, 

 cornu-vaccinum in abundance, and the second with Hipp, or- 

 ganisans and H. cornu-vaccinum ; x and Kynaston correlates 

 his two zones with these. Toucas places his first Hippurite 

 zone in the Upper Turonian, and his second towards 

 the top of the Senonian ; and Kynaston concludes that 

 the Lower Gosau beds represent the upper part of the 

 Turonian and the whole of the Senonian, while Toucas 

 correlates them with the Senonian alone. The age of the 

 Upper Gosau beds, in which very few fossils are found, 

 must still remain somewhat doubtful, but they may re- 

 present the Danian of other areas. 



Of other papers upon the Cretaceous it will not be 

 necessary to say much here. In the Lagonegro district 

 only the Apturgonian is represented (10). It there rests 

 unconformably upon the Lias, and consists of limestones. 

 In the Monte Consolino, near Stilo in Calabria, Bassani 

 and Lorenzo believe that the limestone which forms the 

 crest of the hill includes beds later than the Tithonian (24). 

 Sacco introduces some emendations in the geological map 



1 It should be remarked that Toucas does not attach much weight to 

 the presence of H. cornu-vaccinum and H. organisans. Both of these occur 

 in both zones. H. dilatatus and H. bioculatus appear to be the forms 

 most characteristic of the upper zone. Toucas : Bull. Soc. Geo/. France,
