206 PROCEEDINGS COTTESWOLD CLUB 1906 
Thecrdella and their almost entire absence from the latter, 
indeed I have found only one single valve. 
The Leftena-Beds have been recorded throughout the 
entire length of the western edge of the Cotteswolds, but 
they do not appear to occur to the eastward. They also 
occur in Calvados (Normandy) where the brachiopod 
fauna is particularly rich. 
Immediately upon the Leftena-Beds come about 4 
feet of shales—the “Paper-Shales” of Brodie. Except 
in the upper 8 or IO inches the lamination is very well 
marked, and the central portion when dried can be split 
into very thin laminz. The upper beds when wet are a 
dark chocolate colour, and appear to contain a considerable 
quantity of oil. Throughout the shales flattened speci- 
mens of /noceramus dubius are particularly conspicuous, 
and there are also many specimens of an ammonite not 
unlike Harfoceras exaratum, Young and Bird. Fragmen- 
tary fish-remains also are common. Foraminifera and 
Ostracoda are very rare if not altogether wanting, nor have 
I seen any remains of Alge. Long needle-like spines of 
Acrosalenia crinifera, Wr., and impressions of plates are 
common on the surfaces of some of the shales. It is 
doubtful if these shales are represented by any deposit in’ 
the Ilminster district, but they have been recognised at 
Churchdown, Alderton, and Dumbleton. The upper 10 or 
12 inches of the shales are irregularly bedded, and pass 
somewhat gradually into the amorphous clays which over- 
lie them. 
As will be seen from the section above, there are 
upwards of 7 feet of these grey clays with 6 rock bands 
at intervals. With the exception of Foraminifera and 
Ostracoda in some of the clays, fossils are rare in these 
beds. Dactylioceras Raguinianum and Ff{rldoceras sp. 
are the only ammonites recorded. Isolated blocks of 
lignite occur in the clays and also in the shales. In the
