will be the equivalent of the green bands which form the base of the 

 Barton beds at High Cliff and Alum Bay, and there contain the 

 Nummulina planulata, var. Prestwicliiana, while the lower part will 

 represent the upper beds of the Bracklesham group as seen at Stub- 

 bington and Hunting Bridge. No. 16 of Mr. Prestwich (Nos. xvni. 

 & XVII. of the following section) undoubtedly belongs to the Brac- 

 klesham group, as I shall prove when speaking of the New Forest 

 beds. It is on the horizon of the highest bed seen at Bracklesham 

 Bay, and locally known as the " Clibs " *. 



In the following section the numerals within brackets agree with 

 those in Mr. Prestwich's section, where the numbers run through- 

 out all the Eocene beds seen at the Bay. The Roman numerals 

 refer to the Bracklesham Beds alone, which I have subdivided some- 

 what more minutely. It is well to premise that the colours of the 

 strata at this locality are, for the most part, much altered by recent 

 weathering, and their lithological characters a good deal changed 

 from the same cause.

t Many of the species were, on account of their fragile and weakened con- 

 dition, necessarily det<jrmined and noted on the spot. It is possible that a few 

 errors may thus have arisen ; but the author hopes they are but few.
