either one or two bands of very hard massive Limestone, which 
is seen only towards the East and centre of tlie Inlier, though 
it may occur also to the West but not be exposed. 
This massive bed is quite different in appearance to the 
thin bedded Limestone. It is a rock chiefly formed of frag- 
ments of Crinoids and shells, the whole cemented together by 
calcium carbonate. 
The fossils found in the various exposures of the Lime- 
stone are mentioned below ; the localities are as numbered 
on the map, and are arranged in the order in which one comes 
to them on going from West to East. 
It will be seen that there is no reason to believe from a 
consideration of the fossil evidence that the exposures are in 
different bands, and in this there is agreement with the field 
evidence, which points to the various stretches of Limestone 
having been originally parts of a continuous band of deposit. 
Though corals do occur in the Limestone, it is impossible 
to regard the rock as a coral reef. 
There is no abrupt line at its summit marking it off from 
the beds above ; sandy deposits are constantly found between 
layers of limestone and these gradually increase in thickness, 
while higher up in the succession, sand predominates, and the 
calcareous matter is in layers of nodules in the sand. Whether 
these sandy beds immediately above the Limestone are to be 
considered as of Ludlow or Wenlock age is uncertain. 
Recently the hailstone of the Wenlock Limestone of Shrop- 
shire and Herefordshire has been described,' and in the paper 
containing this description there is a reference to the Wenlock 
Limestone of the Usk area.^ It is recognised that in the Usk 
area there is an upper division of “ nodular courses with much 
shale, the chief fossils found being corals,” and a lower “ of 
solid, highly crystalline, stratified limestone.” With most of 
these statements the author of this paper is in agreement, 
though his observations show that corals are not common in 
any of the Limestones and that brachiopods and trilobites are 
far more frequently found.
