palseontological character ; not one species common to both has been 

 found throughout their whole extent. As the Koessen strata con- 

 tain a number of characteristic has fossils, while the fauna of the 

 Hallstatt strata, at least in its general aspect, comes nearer to the 

 Muschelkalk, we may, with some degree of security, here place the 

 boundary between the formations. 



V. The Koessen Brachiopoda. 



At pages 38-64 of his Memoir, M. Suess describes the Brachio- 

 pods on which he founds the palseontological conclusions above 

 detailed. The following table shows their general distribution : —

On the VoRARLBERG and the Salzberg. By M. E. Suess. 



[Proceedings of tbe Imp. Geol. Institute of Vienna, Nov. 14, 1854.] 



M. E. Suess, after having visited the Vorarlberg (in company with 

 M. Escher von der Linth and M. Merian) and the Salzberg in the 

 Tyrol, reports that the sedimentary rocks of the Vorarlberg, although 

 agreeing in many respects with those of the Eastern Alps of Austria, 

 differ from them in several particulars. The Spuller's Alpe and the 

 environs of Stallehr and Schroecker are alluded to as examples of 

 this. At these localities rocks palseontologically and lithologically 

 identical with the liassic strata of Adneth and Kossen, and with the 

 variegated marls of the Eastern Alps, rest on sandstones which are
