and Pyrgulifera. Among the bivalves, Cyrena clacica Palfy may 

 be specially mentioned. 1 



At both localities where these brackish-water beds are known., 

 at Puj and Alvincz, they gradually pass upwards into freshwater 

 deposits containing much-crushed (and therefore undeterminable) 

 gasteropods, very rarely a Unio-iike bivalve, and numerous well- 

 preserved remains of various vertebrates. In the north of Tran- 

 sylvania, where, until recently, but few vertebrate remains were 

 found, Anton Koch (36) determined in a freshwater limestone 

 intercalated in these beds the following gasteropoda : — 



Planorbis aff. elegans F. Edw. 

 Paludina aff. globuloides Forbes. 

 Limnea aff. michelini Deshayes. 



It is evident that not a single species has been determined in such 

 a manner as to be of stratigraphical value. Since the brackish- 

 water deposits correspond to the upper part of the French 

 Garumnian, or to the limestone of Faxo in Denmark, the fresh- 

 water beds must be considered as an equivalent of the uppermost 

 layers containing Nautilus danicus of Northern Europe. It is of 

 great importance to be assured that there can be no doubt about 

 their age. Near Demsus (Csula) the freshwater beds enclose a 

 great rolled block of limestone containing Actceonella. 



Curiously enough, the foraminifera, discovered by Halavats at 

 Szazsebes in a rolled block of limestone (coming from the conglo- 

 merates that are intercalated among the Dinosaur-bearing sand- 

 stones), have a very Kainozoic aspect. L. Loczy (42) determined 

 these foraminifera, and found : 



Alveolina cf. ovoidea A. d'Or- 

 bigny. 

 A. aff. oblonga A. d'Orbigny. 

 Peneroplis sp. 



Orbitolites sp. cf. complanata 



Lamarck. 

 Alveolina sphserica Fort, var. 



haueri A. d'Orbigny. 

 A. cf. elongata A. d'Orbigny. 



Since the Kainozoic facies holds good also for the freshwater 

 shells mentioned above, everything goes to show that the Dino- 

 saurian beds of Transylvania extend to the very dawn of the 

 Eocene, and perhaps even include its basement-deposits. 



The thickness of the Danian deposits of Transylvania, built up 

 of blue and purple clays, red, yellow, blue, and greenish sandstones, 

 and mottled conglomerates, varies according to the different
