the barrier between this Anglo-Germanic and the Anglo-Parisian 
basin. The points of resemblance and difference, and the mutual 
relations of the Neocomian strata in the Anglo-Germanic, the Anglo- 
Parisian, the Jura, and the Mediterranean basins, I hope (should I 
be able to continue my study of these beds) to treat of in a future 
communication. 
The succession of beds which I have described at Speeton, while 
its remarkable parallelism with the equivalent beds in Southern 
Kurope has been generally acknowledged by Continental geologists*, 
has been appealed to by the advocates of several different schemes of 
classification as supporting their respective viewst. Into these 
questions of classification, however, I refrain, for the present, from 
entering.

Discussion. 
Mr. Erurrines stated that he had examined sections in Bruns- 
wick and Hanover, at Hildesheim, and other places, and confirmed 
Mr. Judd’s results. He remarked upon the occurrence of Pecten 
conctus in the Middle Neocomian in England and in the Lower Neoco- 
mian in Germany. 
Sir Cuartes Lyetr noticed the occurrence of anticlinals and con- 
tortions in the Brunswick district, and remarked upon the compre- 
hensiveness now ascribed to the “ Speeton Clay,” and on the cor- 
respondence of the phenomena observed in Yorkshire with those 
presented in the south of England, in passing from Folkestone to 
the Isle of Wight. He also mentioned the occurrence of Ammonites 
Deshayesvi in the Hastings sand at Punfield, as indicating the marine 
and cretaceous nature of that deposit. 
The PresmENT inquired as to the evidence of the representation 
of the Lower Neocomian by Wealden deposits in Germany. 
Mr. Jupp remarked that the Punfield marine band is absolutely en-
