PLEISTOCENE FORMATIONS OF SANKATY HEAD 723 



No. 16, which seems to be the lowermost member of the drift deposits, 

 or its base. So far as the writer knows, this unconformity between 

 the fossiliferous beds and the overlying drift deposits has never before 

 been noticed. 



The general phenomena presented by these upper beds are shown 

 in Fig. 10, in which the vertical scale is about three times the hori- 

 zontal. The thinning of the fragment bed and the unconformity

between it and the overlying white sands, are also shown in 

 Fig. 9.
