458 THE TOARCIAN OF BREDON HILL. [Nov. I903, 



VIII. Summary. 



The evidence of the fossils found on the flanks of Bredon Hill 

 indicates that the so-called ' Upper Lias ' (G 3) of that eminence is 

 equivalent in date to the Cephalopod-Bed, Cotteswold Sands (G 4), 

 and Upper Lias (G 3) of the west flank of the South and Mid- 

 Cotteswolds. 



In that case, to the thickness of the Upper Lias (G 3) of Wotton- 

 under-Edge must be added the thickness of G 4 of that locality, to 

 make comparison with G 3 of Bredon. Then the contemporaneous 

 strata at the two places, instead of being 10 feet and 380 feet 

 thick respectively, become approximately 220 and 380 feet thick. 



G 3, and G 4 in part, are the strata of the Toarcian Stage. The 

 paper gives details concerning the character and development of 

 these strata in the Cotteswolds, on the Dorset Coast, and in two 

 localities in Normandy.
