peat was obtained. Z# do. of tidal alluvium, taken about 
3 feet below surface of the bench, or 5 to 6 feet below the 
general surface of the alluvial deposits. 
The peat bed (3), as I saw it, was not a large exposure, 
and seemed a tangle of roots and rootlets. There were 
no stools of trees zz sz¢u, only branches bedded in the 
peat, which is of a fresh brown colour when dug up. 
The blue clay (4) in appearance is very like the Scro- 
brcularia Clay of our coasts. There was only a thin bed 
of this, which lay directly on the peat. 
The tidal alluvium (5) represents by far the largest 
portion of the Post-Glacial deposits of the Severn, so far 
as they could be seen in this locality. It is a gray brown, 
laminated clay. 
The similarity of the succession of these deposits to 
those I have studied and mapped on the Lancashire and 
Cheshire coasts’ struck me as remarkable, and with the 
object of further comparison I took the specimens 4 and B 
and submitted them to my friend, Mr. Joseph Wright, F.G.S., 
of Belfast, who has kindly examined them for Foraminifera, 
and sends me the following interesting report and list of 
species. The species marked with an asterisk occur also 
in the Formby and Leasowe Beds in Meols, Cheshire, a 
deposit underlying the “Superior Peat and Forest Bed,” 
of which I think the Severn peat bed is the equivalent. 
Taking the Westbury Peat Bed as the representative of 
the “Superior Peat and Forest Bed” of Lancashire and 
Cheshire, the underlying clay, a specimen of which was, as 
already stated, obtained for me by Dr. Prevost, is the 
equivalent in time of the Formby and Leasowe Marine or 
Estuarine Beds. This clay was also submitted to Mr. 
Wright, and found to contain foraminifera; although the
