Discussion. 



The President (Dr. A. Strahan) complimented the Author on 

 producing an admirable piece of work from most difficult material. 

 A point of considerable interest was the possible correlation of 

 the Kent Coal Measures with those of the Forest of Dean. The 

 stratigraphical sequence was of little help ; but, if insect-remains 

 aided in the determination of a hiorizon, they would prove of 

 the greatest importance. 



The Author thanked the President and Fellows for their kind 

 reception of his paper, and, in reply, said that the occurrence of 

 blattoid wings in the Kent Coal Measures was accompanied by a 

 molluscan fauna of some interest which might yet serve to link up 

 the rocks of Kent with the Coal Measures of Somerset. The 

 occurrence of a species of Soomylacins in Kent, and of another 

 species of Soomylacris in the Forest of Dean, was also significant.
