96 PROF. GROOM ON THE CAMBRIAN AND [Feb. 1902, 
At the northern end of the quarry, the flaggy beds are separated 
from the Archean by 1| or 2 feet of grey and whitish-grey quartzite, 
in thin seams separated by bands of sandy shale; into this series 
they pass by alternation. This quartzité appears to be the summit 
of the Malvern Quartzite (see p. 91), the greater part of which 
is faulted out. A calcareous layer in the flaggy series yielded to 
Prof. Lapworth Autorgina cin gulata, Obolella Salteri, Linnarssonia 
sayittalis, and Hyolithus sp... From what is possibly the same 
layer Lobtained Autorgma cingulata var. Phillips and Hyolithus sp. 
Other portions of the flaggy series piclied Scolecoderma antiquissuma 
(Salter) and Hyolithus (7) sp. 
The second series includes a band of impure, greenish-grey, 
elauconitic, sandy limestone a few inches thick. The only fossil 
detected was Scolecoderma antiquissima. The resemblance of this 
series to the uppermost part of the tlaggy beds suggests that the 
fault separating them is not of great importance ; 
The third series is poorly exposed, but appears to occupy a 
considerable area on the western side of the Raggedstone. Judging 
from the débris and from the few exposures seen, it consists chiefly of 
grey, dark-grey, and black sandstones and quartzites ; 
ereen and dark-green sandstones, with subordinate 
conglomerate and coarse conelomeratic grit”; the pebbles 
of the conglomerate, which are sometimes nearly |] inch long, are set 
in a dark-grev, dark-green, or green matrix. These beds, which 
may be over 200 feet thick, have furnished no fossils. 
Of the fourth series the upper beds only are exposed, 
though judging from débris the lower beds resemble these. They 
consist chiefly of green flaggy sandstones with Scolecoderma 
antiguissuind. The dark zone in the middle of the series includes a 
thin conglomeratic band (M 158). The concealed grey sandstones 
are of grey, or greenish-, brownish-, yellowish- , pinkish-, or reddish- 
erey colour. A yellow ish- grey variety is lithologically indistinguish- 
able from a variety of the Malvern Quartzite seen in Winter 
Combe. These grey beds appear to correspond in part with Holl’s 
‘light-coloured felspathic sandstones.’* They are characterized 
by the great abundance of Hyolithus fistula (Holl) ; with this are 
Peurinted H. primevus, sp. nov. and H, malvernensis, sp. nov., and 
probably other species of the same genus, together with Coleo- 
loides (2) sp., Kutorgina Phillips, a minute species of Modiol- 
opsis (2), and Scolecoderma antiquissima, The light-grey sandstones 
are probably overlain by a very compact dark-grey platy sandstone, 
which forms a httle tump near the road in the Hollybush Pass. 
The higher beds consist of green sandstones, with Scolecoderma 
antiquissima, The beds on the northern side of the ae and those 
in Winter Combe seem to belong chiefly to this fourth class.
