ul PREFACE. 
stances, what I have mentioned will be received as a sufficient excuse for the mcomplete 
state in which I am compelled to leave the subject. My thanks are due to Mr. Henry 
Woodward, F.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.
