AJKA AND COSINA 203 



occurring at Ajka, in Bakony, Hungary; and when 

 similar and contemporaneous freshwater shells are found 

 in localities so remote from one another as Western 

 North America and the heart of Europe, the chances 

 are immensely in favour of their having originated at 

 some earlier date than the beds in which they are 

 found. Pyrgulifera can scarcely, therefore, be regarded 

 as indigenous to the Laramie beds. Goniobasis arctica

and G. macilenta, again, appear to closely resemble a 

 little shell named by Stache, Fascinella, of which there 

 are two species, F. eocenica and F. lacustris, found fossil 

 in the Cosina beds of the Karst, in Carinthia, Istria, 

 and Dalmatia. These beds, which contain abundance of 

 Chara, a freshwater plant, are associated with coal- 

 bearing deposits at their base, and they lie between 

 the upper Cretaceous and the lowest Alveolina beds of 

 the Nummulitic limestone, so that, while they may be
