development, except that the Woolhope Limestone is un- 
important and very unfossiliferous. 
There does not seem to be any representative of the Tarranon 
Shales, though these beds are well developed in the Malvern 
area a few miles to the north. 
The Llandovery beds consist of an upper division of fine 
yellow sandstone often very fossiliferous, which contains in 
places thin limestone bands near its summit and layers of shale 
near its base, and a lower division of coarse sandstone passing 
here and there into a conglomerate. 
Besides these beds there occur rocks of uncertain age to the 
west of Huntley which are of the nature of ashy grits. These 
may be of Llandovery or of Precambrian age. 
The Old Red Sandstone, which is unconformable to the 
Silurian beds in the Mendips and probably in the Tortworth 
area as well, is in the May Hill area conformable to them.
