homotaxeous, and for the present nothing is known which would lead 

 us to suppose that one was older than the other. 



It has long been the general opinion that the Graptolites which 

 characterize Barrande's Colonies and his Etage Eel, had originally 

 their home in the N. of Europe, and that from thence they made 

 excursions into the Bohemian basin. In their earlier migrations 

 they could not find complete footing there, and consequently formed 

 a colony which soon died out. Later, viz. at the time of the 

 formation of Barrande's Etage Eel, they established themselves 

 in permanent occupation of the Bohemian basin. 



Formerly, when it was thought that the Graptolites of the Upper 

 Graptolite Schists were co-existent with the Trilobites of the Tri- 

 nucleus Schists, and that their equivalent English Graptolite-bearing 

 beds belonged to the Llandeilo and Caradoc, such a view was very 

 natural. Now, however, the better insight we have attained of the 

 English and Swedish succession has robbed it of all its force. There 

 is now no reason to believe that the Graptolites which inhabited 

 Barrande's Colonies had emigrated from the ocean of the north. 

 Where they came from is, at least for the present, impossible to 

 determine ; but probably the Bohemian Colonies are older than all 

 the Swedish and English beds in which the same fauna is found. 

 Instead of the emigration having taken place as believed hitherto, 

 if we may judge from the facts already obtained, it would rather 

 have taken place in the opposite direction. — Carl Faye. 



II. — Pkof. J. Woldrich — On Pleistocene Canid^. 

 (Imper. Acad. Vienna, Meeting April 4, 1878.) 

 The remains found in the Loess of Lower Austria and in the 

 Caves of Franconia, Wiirttemberg, and Moravia prove the family of 

 Canidce to have been represented in Europe during the " Diluvial " 

 (Pleistocene) period, in its Lupine or Wolf type by the genera — 

 Cyon (2 species), Lycorus (1 sj^.). Cams (1 sp.), Lupus (4 sp.) ; and 

 in its Vulpine or Fox type by the genera — Vulpes (4 sp.) and 

 Leucocyon (I sp.) : altogether 13 species. A nearly complete skele- 

 ton of Lupus Suessi, now in the University Museum at Vienna, 

 was found some years ago in the Loess of Nussdorf, N.W. of 

 Vienna, overlying the plastic clay of Hernals. This species was 

 characterized by a powerful and not very large head, a very strong 

 neck, and a vigorous muscular system. It was more robust than 

 Lupus spelceus ; and intermediate in size between that species and 

 the existing Wolf. The structure of its extremities shows that it 

 Avas fleet enough to pursue even the larger Herbivores and strong 

 enough to overpower them. — Count Marschall.
