 shape, arrangement of chambers, and strength of the costae.

Frequent. The specimens are somewhat small, and have their 

 surfaces ornamented with smooth lougitudinal ridges, without 

 secondary striae. 



The species is not uncommon round our coast in dredgings 

 from depths below 30 fathoms, but it is of very rare occurrence 

 in shore-sands.

 Very common ; the specimens are both triloculine and quin- 

 queloculine. This species is usually regarded as one of the 

 most typical of brackish-water Foraminifera, and its presence at 

 Bognor in such numbers is one of the most noticeable features 

 of the gathering. Further remarks on the subject will be found 

 in the preface to this paper.
