The Secretaet read the following- remarks sent by Mr. Clement 

 Eeid, who was unable to be present: — 



*' The fauna, as far as I can judge, agrees fairly with that of Moel 

 Tryfaen,and contains a similar mixture of species belonging to various 

 depths and indicating different climates. There seems to be no reason 

 for accepting either of these faunas as contemporaneous with the 

 deposit in which it is now found; for, besides the difficulties already 

 mentioned, it will be observed that a large proportion of the shells 

 belong to a sandy bottom, not to a steep rocky coast, such as would
