In the preparation of this account of the Veneridse I have received 

 muQh valuable assistance from Mr. J. C. Melvill and Mr. J. J. 

 MacAndrew, who have most kindly lent me specimens in their 

 collections for examination, and also from Mr. E. A. Smith, to whom 

 I am indebted for much information, not only about shells in the 

 British ^luseiim but about matters which I'equired reference to various 

 publications. I have also to thank ^lons. M. Cossmann, of Paris, 

 and Professor Peyrot, of Bordeaux, for specimens of Eocene and 

 Miocene species, and for information respecting other species from 

 those formations.
