PKESIWICH CRAG-BEDS OF STJPFOLK ANB NOEFOLK. 



345 



The level of this pit is very little above that of the river. There 

 is no superposition with any other bed ; but I consider there are indi- 

 cations of the Chillesford Clay on higher ground between it and 

 Wangford. 



There is another pit one mUe south of "Wangford, again without 

 superposition and but Little above the level of the river. It presents 

 very similar features to the pit on Thorpe common, the beds being 

 light-coloured and pebbly. The common shells are Cardium edule, 

 Mya arenaria, Littorina Uttorea, Purpura lapillus, and a few others. 



Passing thence to the N.E., we find in the cliff at Easton Bavent, 

 from one to two miles north of Southwold, a section of much interest, 

 as it shows distinctly the relation of the Chillesford Clay to the so- 

 called Mammaliferous or Norwich Crag. The section some years since 

 was remarkably clear, and presented the following features (fig. 26).

3. G-rey laminated clay, 4 to 6 feet. 



Sand, pebbles and shells, 3 feet. 



Along part of the cliff I found no organic remains in the clay ; but 

 at the more northern end of the cliff I met with them at one 

 spot in considerable abundance — many with double valves and in 

 the position in which they lived. Leda myalis was common. The 

 following is a list made on a first and on a subsequent visit with 

 Mr. Jeffreys : —

while in the pebbly sands which here underlie the Chillesford Clay,

 by 2 or 3 feet of light-coloured sand, we have found : —
