beds, typical varieties of this rock, the brecciated 



dolomitic and pisolitic or concretionary forms, occuring there ; some of 



the beds are more sandy, some more compact and silicious, and here and 



there are red layers, with soft micaceous, dark and pale-gray sandstones 



having annelid bm-rows or fucoidal markings. In some spots too, dark 



micaceous sandy shales occur, a few beds together, of the entire aspect 



of the shaly silurian zone below. They are sometimes lumpy and flaggy, 



and on being narrowly examined were found at one place, south-east 



of the summit, to contain small, indefinite, plant fragments (probably of 



fucoids) and some small broken fish teeth (?), pointed like those of sharks.*' 



As the axis of the stratigraphic curve forming the hill bends downwards 



towards both ends, these may be among the lowest beds exposed. On 



the north-western side the crushing and disloca-

tion is extreme, the beds next in contact with the 



magnesian sandstone, &c., just described, being flaggy gray sandstones, 



with some coarse red layers and semi-calcareous grits, over which come 



conglomerates, and some of the conglomeratic shale, just now mentioned, 



at the point marked A in the section (fig, 18). Here another fault 



occurs, and a mass of crushed nummulitic limestone is let in between 



conglomerate and red Nahan beds, the junction of the latter with the 



limestone, being also a line of crushing and dislocation, cutting these 



limstones out entirely within a short distance.
