This fauna enables us to refer this bed with certainty to the 
Upper Neocomian. 
The succession of beds described by M. Hosius * as occurring at 
Ochtrup, intermediate between Bentheim and Ahaus, enables us to 
bring into connexion the sandstones of the former place with the 
clays of the latter. 
Under Gault clays, abounding with Belemnites minimus, List., we 
find :— 
(1) Iron sandstone without fossils. 
(2) Clays with septaria, and hard bands containing :— 
Ancyloceras gigas, Sow. sp. (A. Re- | Ammonites Deshayesi, Leym. 
nauxianus, D’ Oro.). Martini, D’ Ord. 
Matheronianus, D’ Ord. Belemnites brunswicensis, Von Stromb. 
These beds are evidently the same as those of Ahaus, i, e. Upper Neocomian, and 
on the same horizon as the ‘‘ Cement-beds ” of Speeton. 
(3) Clays containing Belemnites jaculum, Phil., abundantly, and Bel. bruns- 
wicensis, Von. Stromb., rarely. These beds correspond with the upper 
part of the Middle Neocomian of Speeeton. 
(4) Unfossiliferous clays. 
(5) Sandstones, sometimes coarse and quartzose, and at other times ironshot. 
From these no fossils are recorded, but they are probably the same as 
those of Gildehaus. They lie directly upon 
6) The ‘“‘ Walderthon.” 
Along the Teutoburger Wald, from Ibbenbuhren to Bielefeld, 
the beds of yellowish-brown sandstone, like those of Bentheim, 
and of considerable thickness, frequently form the highest point of 
the chain. These beds at times pass into limestones and ironstones 
and are associated with thick beds of blue clay. Everywhere they 
appear to be characterized by the abundance of large specimens of 
Pecten cinctus, Sow. The same strata occur similarly in the range 
of the Lippischer Wald, which forms a continuation of the Teuto- 
burger Wald in a south-easterly direction, and in the chain of the 
Egge Gebirge, which from the former runs in a southerly direction 
from Detmold to near Warburg +. 
From the Sandstones of the Teutoburger Wald the following fos- 
sils have been recorded, which clearly indicate their identity with 
the similar strata of Gildehaus and Losser, and that, like these, they 
are to be referred to the same horizon as the Tealby Limestones and 
the middle portion of the Speeton Clay.
