RED AND NORWICH CRAGS. 
large portion of the skeleton, at any rate, was found. It seems 
however, rather singular that only one tooth should have been 
preserved. This is the most northerly point to which the 
Mastodon has been traced, for it is entirely absent from the 
Cromer Forest-bed. 
At Burgh-next-Aylsham we meet with the last section of the 
Norwich Crag, as distinct from the newer Wejbourn Crag, and 
here also the so-called Chillesford Clay occurs in considerable 
thickness.

Section at Burgh Kiln, near Aylsham, 
(H. B. Woodward.) 
The following list includes all the species recorded from this 
locality:— 
Littorina littorea. 
Scalaria groenlandica. 
Trophon antiquus, var. striata. 
,, ,, var. contraria. 
Turritella terebra. 
Astarte borealis. 
,, compressa. 
Cardium edule. 
Cyprina islandica. 
Corbula gibba. 
Oyclas cornea. 
Corbicula fluminalis. 
Leda oblongoides. 
Lucina borealis. 
Mactra ovalis. 
Mya arenaria. 
Tellina lata. 
,, obliqna. 
There is nothing in the list to distinguish the deposit from the 
Weybourn Crag, except the absence of Tellina balthica ; but this, 
and the occurrence of the thick mass of clay, seem to support 
the contention of S. V. Wood, junr., that the deposit belongs to 
the older series.
