S. V. Wood— The Long Meadend Bed. 



To these I Lave been able to add from other sources ^ some others 

 which are given in italics in the subjoined list, those in the Edwards 

 collection appearing in Eoman letters ; and together they represent 

 tlie whole molluscan fauna which up to this time has, so far as I 

 can ascertain, been obtained from this bed. 



It is not unlikely that collectors from the Hampshire beds may be 

 able to add to the list, and if so I should feel obliged to them if they 

 would favour me with particulars of such. The columns to show 

 the presence of the shells in the Upper Eocene of Belgium are based 

 on the Bruxellian and Laekenian lists of Nyst, in Prof Dewalque's 

 " Prodrome d'une description geologique de Belgique," pp. 401 to 

 407, and those showing this in the Upper Eocene of France are based 

 on Deshayes' " Animaux sans vertebres dans le bassin de Paris, 1866." 

 The negative occurrence of them in the column for the Lower 

 Tongrian is based on the lists of Bosquet in the same " Prodrome," 

 pp. 410 to 416.

 Mactra depressa, and Corhula oblonga, similar notes, and also specimens in my 

 possession with their names and localities affixed to them in my father's handwriting.
