The Pleistocene deposit at the Copford brick-field consists, in an 

 ascending order, of a bed of black vegetable matter, or peat, from 

 six inches to one foot in thickness, resting immediately upon the 

 "till:" from this stratum the following shells were procured, which 

 were named for the author by Mr. S. P. Woodward -.— Vertigo pa- 

 lustris ; V. edentula ; V. pusilla ; V. pygmea ; V. substriata ; Azeca 

 tridens ; Acme fusca ; CarycMum minimum ; Zua lubrica ; Clausilia 

 rolphii ; CI. nigricans ; CI. bidens ; Succinea pfeifferi ; S. putris ; 

 Aplexus hypnorum ; Limnius palustris ; L. truncatulus ; Planorbis 

 spirorbis ; P. vortex ; Pisidium pusillum ; Helix nemoralis ; H. hor- 

 tensis ; H. urbustorum ; H. lapicida ; H. rufescens ; H. hispida ; H. 

 pulchella ; H. lamellata ; H. spinulosa ; H. fnlva ; Zonites rotunda- 

 tus ; Z. ruderata ; Z. cellarius ; Z. radiatulus ; Z. nitidulus ; Z. lu- 

 ridus ; Z. crystallinus ; Pupa anglica ; P. vmbilicata ; P. marginata. 



Above the peat is a bed of clay and detritus about one foot thick, 

 containing many of the land and freshwater shells cited aljuve ; next 

 above this is a second layer of peat with shells. 



At the southern extremity of the author's section, the order of the 

 beds was as follows: — 1. Diluvial clay, 3 feet. 2. "White sand with 

 shells, 3 feet. 3. White calcareous marl with shells, together with 

 the bones of the elephant, ox and deer. 4. Peat with shells {Val- 

 vata piscinalis), 6 inches. 5. Blue clay with freshwater shells. 



The author suggests that this deposit is the bed of an ancient 

 pond, which occupied a depression on the surface of the till.
