The foregoing assemblage of fossils is consistent with the beds 
being either of Ludlow or of Wenlock age. 
A(17). This band of purple rhyolite is seen below the sedi- 
mentaries, near the end of the point south-west of the Stone Cross. 
It occupies the coast, which follows its strike, as far asa point west 
of the Penitential Station. 
A (19) is a purple-banded rhyolite, with very well-marked flow- 
structure. It occupies the coast around the unnamed inlet due west 
~ of Carhoo. : 
A (20). These ashes dip at 20° south 35° east, and contain frag- 
ments of banded and compact rhyolite and of slate. 
A (21) occupies the coast around the little bay opposite Carrignea. 
It is a fossiliferous band of sandy limestone, weathering yellow. 
A (22) is a thin band of pale coarse ash, containing fragments of 
rhyolite and slate, which sometimes are 6 inches in length. 
A (23) is a well-marked, fine-grained, pale-green ash. Itis some- 
times remarkably well-banded, and elsewhere shows dark-green oval 
markings about a quarter of an inch long. Both these structures, 
though visible on the freshly-broken sirface, are better seen on 
the weathered surface. Some thin ash-bands of a coarser character 
are intercalated with the fine ash. 
A (27). These calcareous flags, with coral-limestones and earthy 
slates, occupy both sides of the httle inlet south-east of Carrigeam, 
and show the following bands: at the top :—
