We group all the exposures of limestone on the slope of the hill 

 south and east of the Chair in one broad band (C). This limestone 

 is sometimes red and horny, but is generally grey and more or less 

 crystalline. Fossils ' are more plentiful in it than in any of the 

 other bands — Primitia M'Coyi, lllcenus Bowmani, and Sphcerexo- 

 chus mirus being specially abundant. It yielded : —

The highest band of limestone (D) is exposed in the field imme- 

 diately north-west of the Chair Farm, and here a considerable 

 thickness is seen. The lower beds at this locality consist of grey 

 limestone which becomes earthy in places and sometimes has shaly 

 partings. The upper beds are chiefly reddish and horny, and contain 

 few fossils, the commonest being Favosites fibrosa. 



From the band (D) we obtained the following forms : —

 wish to express our most hearty thanks.
