COEALLINE CRAG. 
Fig. 4. 
Broom Pit^ near the Keeper^s Lodgey Gedgrave, 
Scale, 20 feet= 1 inch. 
1. Soil. 
2. Calcareous sands and rubbly limestone, crowded with Bryozoa, 
especially large masses of Fascicularia. A few perfect small 
shells. 
3. Calcareous sands with scattered Fascicularia and other Bryozoa, and 
small shells. 
4. False-bedded calcareous sand, with broken shells, mostly at the base. 
Perfect valves of Psammobia —high up, lower down Cardium 
decorticatum, Pecten oyercularis, P. Gerardi, Nucula nucleus, &c. 
5. Similar sands, with a thin bed of hard marly limestone at the base. 
6. Shell beds. Large shells abundant, especially in the lower part. 
Cyprina islandica, G. rustica, Thracia, Panopoea, Pectunculus, Pecten 
maximus, &c. Cetacean vertebra at point marked + . (This is the 
bed from which most of the shells are obtained.) 
Prof. Prestwich considers that the lower strata here belong 
to his zone d, while the upper ones represent the lower part of 
zone e. As an example o£ the fauna from a single locality it may 
be interesting to give the following list of the mollusca obtained 
. by S. P. Woodward in 1863 from the Broom Pit. He remarked 
that bivalves were abundant; univalves, except Turritella 
incrassata, comparatively scarce.
