Between Chillesford and Thorpe, where Norwich Crag appears, 
the Rev. O, Fisher* has traced a series of pits in which are found 
beds with M^a in the position of life He also refers the shelly 
sands overlying Coralline Crag, seen in the pit three-quarters of a 
mile north-east of Sudbourn Church {see ante, p. 98) to a shoal- 
deposit derived from the Mya-bed (= Chillesford Crag), on 
the ground that while many of the commoner shells of the Red 
Crag are at this place rare or altogether absent, those of the 
Mya-bed are in profusion.” 
The cliffs at Aldborough are now built over and sloped, but 
the Crag is seen in pits in the neighbourhood, and is very shelly, 
being protected from decaicification by the overlying Chillesford 
Clay. Prof. Prestwich observes that the upper division of the 
Quart. Journ. Geol. Soc., vol. xxii. pp. 19-28. (1866.)
