Characters. — Shell straight or slightly curved ; chambers very nitmerous, 

 narrow, arcuate, neat. Foramina usually conspicuous. 



There is a considerable range of variation, in minor particulars, amongst the 

 feeble biserial forms of Bulimina included under the sub-type Bolivina. We can, 

 however, find no single character in B. antiqua as figured by d'Orbigny, and 

 subsequently by Egger, which can be said to form valid ground for even varietal 

 separation from his previously described recent species B. punctata. 



Occurrence. — Bolivina punctata is shown in the ' Challenger ' and ' Gazelle ' 

 Reports to be a cosmopolitan species. Its bathymetrical range extends from 2 to 

 2740 fathoms. As a fossil it is of very common occurrence. It has been recorded 

 from the phosphatic chalk of Taplow, the Eocene London Clay, the Oligocene of 

 Elsass, the Miocene of Malaga, Italy, Vienna, and Muddy Creek (Victoria), and 

 from the Pliocene of Italy, Garrucha (South Spain), and St. Erth. In the 

 Coralline Crag it has been found in every zone examined.
