and probably derived from a Tertiary day. They differ somewhat 

 from Karrer's specimens in respect of the rapidly increasing breadth 

 df the shell, which is also of practically uniform thickness from the 

 initial to the final chambers, i.e. the opposite faces of the shell are 

 practically parallel. Karrer's specimens were from the Miocene of 

 Kostej in the Banat. As a recent species it occurs in all the great 

 oceans, most of the records heing from dee]) water.

A single, well preserved, and typical fossil specimen which 

 agrees perfectly with Brady's type figure (suprd). The shell is 

 hyaline and the sutures very strikingly limhate. 



Millett (suprd) goes at some length into the relationship of this 

 variety with other species. 



The variety is at the present day confined to tropical and sub- 

 tropical seas. Our knowledge of its geological range is somewhat 

 doubtful, for reasons explained by Millett.

A few small fossil specimens which present the characteristic 

 plications of the chambers which mark this species. At the present 

 day this is a tropical shallow-water species and under favourable 

 circumstances reaches a very large size. We have specimens from 

 the Philippine Islands £ inch in length. The original record by 

 Eeuss was from the Oligocene of the south of France.
