sandstone, which in general contains little cementing matter, 
and encloses principally the following fossils :— 
Pecten equicostatus. © Exogyra columba. 
Pinna decussata. Inoceramus concentricus. 
pyramidalis. 
The beautiful rocky country formed by this deposit and the 
upper-chalk-sandstone are generally known, and are probably 
unique of their kind. 
In Silesia the lower greensand is distributed chiefly between 
Goldberg, Lowenberg and Bunslau. At Seiphenau, in the 
neighbourhood of the first locality, it forms rocks 80 feet in 
height, is exposed to view in several quarries, and consists of a 
few very thick seams of sandstone, separated by thin slaty layers. 
The stone is light gray, coarse-grained, has very little siliceous 
matrix, and contains very few fossils. The quader at Langen- 
berg, near Pilgramsdorf, is similar in appearance ; but it is best 
exposed to view in the Moissen quarries close to Lowenberg. 
There we have above 8 feet of stratified sandstones, beneath 
which are 40 feet of lower greensand, in three or four seams, not 
much divided; the upper beds are fine-grained, the lower re- 
semble conglomerate ; those of the middle contain in a thin layer 
numerous but generally indistinct fossils ; especially Pecten asper 
and P. equicostatus. 
Between Lowenberg and Bunslau, north-east of Wenig Rag- 
witz, a seam of coal is explored which is from 12” to 18" in thick- 
ness ; resting upon which occur, beginning with the lowest,—

Similar beds of sandstone and clay occur beneath the coal, 
none of which appear to contain fossils ; it is therefore impos- 
sible to decide with certainty whether this formation belongs to 
the quader or to the Hastings sandstone; the first however 
appears to us the most probable. 
At Bunslau the lower greensand consists of seams of sand- 
stone from 6" to 1' in thickness, which alternate with whitish 
somewhat sandy beds of clay of equal thickness; the celebrated 
Bunslau earthenware are made of this clay. We have not ob- 
served any fossils in it.
