MOOKE — ABXORilAL SECOND AEY DEPOSITS, 



509 



Windsor Hill and at Sntton, the shells have often lost their outer 

 structure ; for which reason care is needed in the determination of 

 species. Xearly all the ]\Iollusca quoted by ^Ir. Tawney from the 

 Sutton series are present, and others in addition ; but, unfortunately, 

 from that gentleman having missed the key to the interpretation of 

 the age of the beds, and from the altered appearance of the shells, 

 many of them are only varieties of species that have already been 

 described.
