THE FORAMINIFERA OF A POST-TERTIARY DEPOSIT 
IN SUSSEX. 
By F. W. Millett. 
The material submitted for examination consisted of about three 
ounces of a somewhat coarse sand, containing many minute mollusca 
and foraminifera, together with a few ostracoda and many fragments 
of echinodermata and polyzoa. There were also present numerous 
glauconitic internal casts of foraminifera, and many of the shells 
contained iron pyrites. 
When placed in a sieve of eighty threads to the inch, about half- 
a-dram of fine material passed through, whilst the grains which 
remained behind were almost uniform in size, few of them exceeding 
the one-tenth of an inch in diameter. In this coarser portion the 
foraminifera were very abundant, but much weathered and rolled, 
and consisted principally of the common forms of the eocene beds of 
Hampshire, viz. —JSfummulina variolaria, Alveolina sabulosa and Discorhina 
trochidiformis . 
In the finer portion there was much greater variety, and nearly all 
the specimens -were in good condition, many of them being recent. 
It is evident that the deposit contains foraminifera derived from the 
eocene and possibly from the cretaceous formations, mixed with a large 
number of recent specimens, the remainder being composed of tertiary 
forms, to which, under the circumstances, it would be difficult to 
assign the exact horizon. Some of the species are represented by 
specimens both recent and fossil. 
N.B.—This note, necessary to explain the incongruous concourse of 
species, was omitted from Mr. Bell’s communication to the Society.
