HOERNES — ALPINE TRIAS.

Scliwarzeiibachj — 2nd, others discovered by M. Lipoid on Mount 

 Obir, N.W. of Eisenkappel in Lower Cariuthia, — 3rd, another series 

 from Esino in the Val Pelaggia, on the eastern border of the Lake 

 of Como, which were kindly submitted for the author's examination 

 by M. Escher, — and lastly, some fossils from the Hallstadt strata, 

 lately found by Dr. Fisher, of Munich, at Sandling* and at Selt- 

 schen, near Aussee in Styria. 



The Esino fossils were found in a dark-grey or black dolomitic 

 limestone in the detrital accumulations (schutt-halden), on the 

 northern slope of the Val Pelaggia. The limestone is intersected by 

 veins of white calcareous spar, and has a slight bituminous smell 

 when struck with a hammer. MM. Escher and Curioni found also 

 Crinoidal joints in this limestone. 



The number of species common to the several fossil faunae here 

 referred to is but small, but may however be regarded- as sufficient 

 to indicate that the Hallstadt and the St. Cassian strata are closely 

 related, and that in a palaeontological point of view the dolomitic 

 limestones of Esino, Hall (Tyrol), Unterpetzen, &c., are members of 

 the extensive St. Cassian series. 



The following table exhibits a synoptical view of the relative oc- 

 currence of the Triassic fossils described in Dr. Moritz Hoernes' 

 paper.
