by crushing the rock. It is pi'obable, but not quite certain in the 

 absence of sections, that the Alveolina Hauerii of d'Orbigny^ from 

 the Miocene of Nussdorf is of the same type. Schwager's specimens 

 came from the ^/I'eoZ/no-limestone of the Wady Natfe in the 

 Arabian Desert (Libj'an Stage).

This species, viewed towards the septal face, gives an ovate, pointed 

 outline. It was suggested by Schwager that it may represent an 

 immature stage of the foregoing species. It was found by that 

 author associated with A. elUpsoidalis from the Wady Natfe, Arabian 

 Desert.

 A good vertical section of the above species occurs in one of the 

 slides. It is recognized by the pointed aboral end and the fine 

 arenaceous structure of its test. 



As a fossil B. capreolus makes its first appearance in the Eocene 

 of the Bavarian Alps ; it was also found in the Clavulina-Szaboi 

 beds of Hungary ; and it is known from the newer Tertiaries of 

 Italy (Mio-Pliocene). The depths at whicii this species occurs in 

 recent deposits ranges from fairly shallow water to about 700 

 fathoms. At the present day it is generally found in the North 

 Atlantic Ocean.
