Messrs. Cuvier and Brongniart remark that the nummulites are found only in the lowest beds of the calcaire grossier, to which belongs also the cerithium giganteum. I am enabled by the information of Mr. Holloway, who pointed out to me these fossils at Bracklesham in Selsea, and also in Stubbington cliff near Portsmouth, to add this very strong circumstance of agreement with the French strata.
It is impossible not to be struck with the identity of the fossil shells of the sandy beds of Liancourt with those of Stubbington.
At the former of these places are found:
Nummulites lenticularia |
lævigata |
Turritella terebellata |
imbricataria |
Crassatella sulcata |
Venericardia planicosta |
Sharks' teeth |
The whole of which are to be found at Stubbington.
