In a former paper, " On the English Crags, etc.," Geol. Mag., 

 June, 1871, the Butley Crag was considered to be a shallow water 

 deposit of the Upper Crag, and that near Shottisham Creek, by the 

 river Deben, to be a deep water one ; and in comparing the fauna, 

 the latter, I think, should be contrasted with that of the Chillesford 

 stage, which I consider to be indicative of much deeper water than 

 either the Butley or Chillesford (Scrohicularia) pits. The following 

 species do not occur in the shallow water deposits, and are from the 

 Shottisham Creek pit.
