Characters. — More or less oviform and compressed, sometimes subfusiform ; 

 suboval in transverse section ; broad about the middle, rounded below, obtusely 

 pointed above. Five or six chambers, variable in size, irregularly subspiral. This 

 form is nearly allied to the typical P. comm,nnis. 



Occurrence. — Polymorphina sororia is stated in the ' Challenger ' Report 

 to have been found at two stations in the North Atlantic, west of Ireland, 

 at depths of 808 and 1443 fathoms ; also midway between Cape of Good Hope and 

 Kerguelen Island (1375 fathoms). It was also found by the 'Gazelle' oft* Sierra 

 Leone, at a depth of 367 fathoms (Egger). 



As a fossil it has been recorded from the Chalk of Taplow ; from the Oligocene 

 of Elsass and Pietzpuhl ; and from the Pliocene of Belgium and St. Erth. The 

 Crag specimens were obtained from Broom Hill (zone d) and Aldborough (zoneg).
