The shells were, for the most part, fragmentary and in 
many instances showed glacial striations. 
The sandstones immediately above the Carboniferous 
Limestone were next examined in Allinson's Quarry. The rock 
is of a bright yellow colour and was found to contain Cyathaxonia, 
caninoid Campophyllmn, and a few brachiopods. It was con- 
cluded that these beds belonged to the zone Ds. 
Offa's Dyhe was then crossed on the way to Llawnt, where 
further exposures of the Carboniferous beds were examined. 
In Llawnt Quarry the beds of Carboniferous Ijimestone are 
considerably bent and contain two layers of shale, the dip on 
one side of the exposure amounting to 40° towards the east. 
Although very near to the base of the series these beds 
are high in the zone D2, the following fossils occurring : — 
Dihunophyllum Muirheadi. 
Lonsdalia duplicata. 
Liihostrotion irregulare. 
Syringopora sp. 
Spirifera hisulcata. 
In the road below the quarry the Bala shales are exposed, 
their dip and strike both differing considerably from those of
