Y. Correlation oe the Mendip and Bristol Areas. 



The correlation of the palseontological sequence in the Mendip 

 and Bristol areas is treated somewhat fully in my paper on the 

 Burringtou-Combe section, 1 but a detailed examination of the 

 Mendips has since shown that the comparison there instituted, 

 which was based solely on a knowledge of the Burrington section, 

 requires considerable emendation. 



In view of the close general similarity of the faunal sequence in 

 the Mendips with that observed in the Bristol area, the following 

 notes are confined almost entirely to the points of difference. 



The CzmsTOPORA-Zone. 



A separation of the lowest portion of the Avonian as a distinct 

 zone, namely, the Mocliola-Zone, is less justifiable in the Mendips
