Vol. 58. ] ASSOCIATED BEDS OF THE MALVERN HILLS. 95 
At the southern end of the Raggedstone he described, in descending 
order, the following succession :— 
Olive-green massive beds. 
Thinly-laminated micaceous sandsione. 
Hight-blue calcareous sandstone, with a thin bed of limestone. 
. Dark-purple and purplish-black sandstone. 
Sandy shales, with worm-tracks. 
These beds Holl placed below the horizon of the lava of the more 
northerly exposures, but above the lowest beds. Both on the 
northern and southern parts of the hill, the beds appear to be 
less satisfactorily exposed than when Holl examined them; but 
careful cxamination of the ground shows that, at any rate in part, 
Holl’s succession will not hold good. He does not seem to have 
detected the fault crossing the series at White-Leaved Oak,! and in 
the northern part of the hill the supposed lava has been shown by 
the present writer to be a dyke crossing the bedding.” 
The formation in Raggedstone Hill exhibits a difference in deve- | 
lopment in three or four different areas. There is, firstly, a series 
consisting chiefly of thin flaggy sandstones, interstratified with 
sandy shales: these are seen only on the western side of the big 
quarry at White-Leaved Oak.* Secondly, a set of more massive 
green sandstones, interstratified with dark-green or black sand- 
stones: these are exposed immediately west of the flaggy sand- 
stones, from which they are separated by afault.* Thirdly, a set 
of dark-grey and grey sandstones or quartzites, with green sand- 
stones, seen to the north of the big quarry. And lastly, a thick 
series of green sandstones, apparently including in the middle 
a band of fine-grained, dark-green or grey sandstone, overlain by 
variously-tinted light-grey sandstones’; this series occupies the 
north-western corner of Raggedstone Hill. The mutual strati- 
graphical relations between these portions of the formation are not 
clear ; but the available evidence suggests that they constitute, on 
the whole, series following each other in the order just given, but 
possibly with some overlapping ° of the members in some or all 
cases. 
The flaggy beds consist chiefly of thin flags of green sandstone, 
separated by equally thin shaly seams. In places the beds become 
calcareous, and at one spot small lenticular patches of impure light- 
green limestone are seen, and in two others a very hard, compact, 
impure, brown or grey limestone, 2 or 3 feet thick.” Towards the 
upper part of the series thin beds of dark-grey sandstone come 
in; and the uppermost beds seen consist of more massive green, 
dark-green, or dark-grey sandstone separated by shaly beds.

should probably be extended somewhat in width towards the south. 
* This term is not used in a stratigraphical sense.
