336 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Feb. 23, 
eastern counties of England; and it was from a block of this kind in 
Suffolk that one of Sowerby’s type specimens of Pecten cinctus was 
obtained. 
According to Murchison and Nicol’s Geological Map of Europe 
(1856), Cretaceous strata containing Perna Mullet. and Crioceras 
Duwvali occur at the village of Losser, near to Oldensaal, on the 
western borders of Holland. These beds have been described by M. 
Ferd. Romer *, to whom the fossils collected at Losser have been 
submitted by the General Commission for the Geological Examina- 
tion of the Netherlands. Under a thin covering of the sandy drift, 
which completely masks all the country around, is found a bed of 
yellow ironshot sandstone, very similar to that of the Teutoburger 
Wald, and containing the following fossils, which enable us to 
refer it, without doubt, to the Middle Neocomian :— 
Ammonites Decheni, Rom. (A. bidi- 
Lima longa, Rom. 
chotomus, Leym., junior). 
Lima, sp. (the same that is abundant at 
Ancyloceras (Crioceras) Duvali, Lév. Gildehaus). 
Hxogyra sinuata, Sow. Trigonia, sp. 
Pecten cinctus, Sow. Pholadomya, sp. 
Perna Mulleti, Desh. Goniomya, sp. 
Pinna (the same species as in the Teu- 
toburger-Wald Sandstone) near to 
Pinna Neptuni, D’Orb. 
Heteropora ramosa, Hém. 
3. Westphalia.—Passing eastwards we find the first exposures of 
the Neocomian of North-western Germany in the hill-group of Bent- 
heim. Here the formation is represented by beds of yellowish grey 
sandy limestone, very similar to that of Tealby, which passes insensibly 
into hard sandstones, and in places contains thick beds of blue clay. 
These beds and the similar ones of the Teutoburger Wald were for- 
merly classed with the Quader; the settlement of the question of 
their true age is due to Professor Ferd. Romer. The list of the 
fossils which he gives, from Gildehaus, near Bentheim, shows that 
these limestones, like those of Lincolnshire, are referable to the 
Middle Neocomian. The following is the list :— 
Crioceras Duvali, Lév. | Avicula Cornueliana, D’ Ord. 
Belemnites lateralis, Phd. Lima, sp. 
Panopea neocomiensis, Desh. sp.(large | Pecten cinctus, Sow. 
form). orbicularis, Sow. 
Thracia Phillipsi, Rom. Exogyra sinuata, Sow. 
The Neocomian strata stretch in a band, running in an easterly 
direction from Bentheim to a point on the Ems, between Rheine 
and Salzbergen. At the eastern end of this band the beds pass into 
black clay full of septaria. 
In the same district, but considerably to the south, near Ahaus, 
there occur black plastic clays, containing a bed, a little over one 
sie ee of pyritous argillaceous stone, containing the following 
ossils :—
