lay down its geographical range. In the earlier Tertiaries of North Germany, in the 
Miocene of the Vienna Basin, of Lower Bavaria, and of Kostej in the Banat, in the Pliocene

found; and the presence of a similar, if not identical, variety in the Tertiaries of New 
Zealand is recorded by Herr Stache.
