minimus, Ammonites varians, A. Coupei, A. curvatus, It is perhaps 
likewise characteristic that Inoceramus Brongniarti and I. Cuvieri 
are not met with in this formation. 
Of the localities where it is very distinctly exposed I will 
mention the high road just above Wrisbergholzen, the Ringel- 
berg at Salzgitter, the quarry near the high road to the south of 
Simmenstedt close to Brunswick, the sand-pit at Goslar, and the 
quarries at Langelsheim. 
The true greensands are more rare. We meet with them 
first of all in the south of Westphalia, on the southern limit of 
the chalk range, overlying the (flozleeren) sandstone. 
Close to Werl, on the east, this formation is exposed in several 
quarries ; that of Brunks affords the following section :—

5. Gray, sandy, compact, stratified marls, which contain 
numerous small granules of silicate of iron; the 
seams, from 4 to 6 inches in thickness, contain 4Am-

striatus, Pecten laminosus, &c.:—used for building 6 
6. A more marly and softer stone, with very little silicate 
of iron. 
The last two layers belong to the greensand, and they also 
occur close to Bausenhagen, on the southern declivity of the 
Hartz. 
The Greensand is well exposed in a fine quarry a few hours 
(stunden) to the south of Werl, on the northern side of the valley 
of the Waterlappe. Beneath a covering of soil, 2 feet in thick- 
hess, are 10 feet of greensand, reposing with a slight northern 
inclination on the (fldzleeren) sandstone of the coal formation, 
which rises from the south at an inclination of 70°. The green-
