VOL.- XIV. (1) FOREST BED—-GEOLOGY 2} 
great yield of the bed No. 5, amounting to 86 species 
and 3 varieties, as_ from the position of the alluvium and 
its appearance I thought it would turn out to be largely a 
river deposit. Bed No. 4 is very remarkable as containing 
Psammosphera fusca, an arenaceous species hitherto only 
recorded from deep water, whilst from the nature of the 
clay and its position J infer that it was deposited in shallow, 
probably tidal water. The specimen in Bed No. 2 not having 
been collected by me, I cannot describe its locality except 
as underlying the peat. It has every appearance of being 
an estuarine deposit. It evidently lies upon an eroded 
surface of Keuper Marl. 
In connection with this great yield of Foraminifera, a 
question that naturally suggests itself is—‘ Have they lived 
in the waters adjoining to where their remains are found ?” 
Professor Sollas, in an interesting paper on ~ The 
Estuary of the Severn and its Tributaries,” considers that 
he has found evidence that marine organisms, amongst 
which are fragments of sponges, have been washed up 
the Severn from the deeper waters outside. He has found 
them in the modern mud of the Severn, and cannot other- 
wise account for their presence. The Westbury beds are 
however further up the Severn than the localities Prof. 
Sollas mentions. 
Judging from the condition of the Foraminifera and their 
fragility, Mr. Wright considers that they have lived in the 
locality where the specimens of clay were taken, and pro- 
bably in brackish water. Prof. Sollas is probably right in 
his inference as regards the remains found in the Severn 
muds that he examined, but as regards the Foraminifera 
treated of in this paper, I agree with Mr. Wright’s views. 
The succession of events would appear to be these, com- 
mencing at the earliest Pleistocene.
