ridges and escarpments formed by the resistance of the calcareous 

 grit, and the denudation of the Oxford Clay, characterize all the hills 

 around Scarborough, the Kelloway Eock occupying the valleys. At 

 Newton Dale the upper beds tlun out, and there is a paucity of 

 organic remains, compared with Hackness and Scarborough, but 

 Gryphcea dilatata, Trigonice, and Am. Gulielmi may be obtained.
