At this place, however, the clays are associated with beds of lime- 
stone and coarse sand, passing into oolitic and conglomerate iron- 
stones. These beds have yielded the following fossils. 
Pycnodus Hartlebeni, Ram. Avicula Cornueliana, D’ Orb. (A. ma- 
Meyeria ornata, Phil. sp. croptera, hom.). 
Serpula angulosa, Rom. Modiola rugosa, Rom. 
Belemnites lateralis, Phil. Thetis Sowerbyi, Rom. 
Ammonites bidichotomus, Leym. Thracia Phillipsi, Rom. 
Nautilus, sp. Panopxa Romeri, Gein. 
Turbo clathratus, Rom. Pholadomya alternans, Rom. 
Exogyra sinuata, Sow. Rhynchonella. 
Pinna gracilis, Phil. (P. rugosa, Rom.). 
Very similar to those of the Osterwald are the beds exposed at 
several points in the valley of the Inner, especially at Steinlahde, 
near Salzgitter, where the ironstone has for a long time past been 
extracted by means of a great open working. The section seen 
here is as follows, the beds dipping E. 63°. 
(1) Flammenmergel (Gault), with the usual characters, light-co- 
loured and variegated clays, curiously striped (fancifully 
supposed to resemble flames, hence the name) ............... 20 feet seen. 
(2) Variegated purplish-red, yellow, and bluish clays, with 
several irregular layers (each about 6 inches thick) of argil- 
laceous limestone. Through these beds fragments and ooli- 
tic remains of ironstone are disseminated, but sparingly... 40 feet. 
(3) Ironstone conglomerate, made up of irregular noduies of 
various sizes and of perfectly round and beautifully po- 
lished oolitic grains of brown ironstone. The bed is 
crowded with fossils, the gigantic Pecten cinctus being 
especialllyabund anitespecsseeneneecee eases eee eae ree reece 15 feet. 
(4) Light-brown calcareous sandstone (resembling that of Lin- 
colnshire), containing enormous numbers of Pecten cinc- 
tus, Hxogyra sinuata, and other fossils. ......... Thickness 10 to 25 feet. 
(5) Variegated clays similar to 2. 
The beds in this neighbourhood are evidently very variable in 
character. A shaft sunk near the mine exhibits very pyritous blue 
clays, with many bands of argillaceous limestone, covered by beds of 
white sand and sandy limestone. The oolitic ironstones, with pre- 
cisely similar characters to those of Steinlahde, are also dug at 
some other points in the neighbourhood of Salzgitter, as at Oster- 
holz. These ironstones yield the following fossils, which enable us 
to refer the beds with certainty to the horizon of the Middle Neo- 
comian. We have already pointed out the striking similarity, both 
in mineral character and fossil contents, of these beds to those of 
our Tealby series.

It is interesting to notice that the Flammenmergel (the represen- 
tative of the Gault) appears, at Steinlahde and at some other points,
