﻿ii PREFACE. 



stances, what I have mentioned will be received as a sufficient excuse for the incomplete 

 state in which I am compelled to leave the subject. My thanks are due to Mr. Henry 

 Woodward, E.R.S., of the British Museum, in whose custody Mr. Edwards' collection 

 now is, for great facilities afforded me in the production of the present small contribution 

 to the British Eocene Mollusca. 



S. V. WOOD.
