 the Red Crag may be seen capping the Coralline Crag ; and I have there collected the following fossils : —

Pit one mile east of Sudbourne Church.

Astarte obliquata. Tellina obliqua.

Cardium edule. Cypraea europaea.

Mactra ovalis. Littorina littorea.

Mya truncata. Nassa granulata.

Mytilus edulis. Purpura lapillus.

Pecten opercularis. Turritella incrassata.

To these a list of the late Dr. Woodward adds : —

Artemis lentiformis. Natica catena.

? Cardium Parkinsoni. ? Trochus zizyphinus.

Venus fasciata. Trophon antiquum*.

Buccinum undatum.

Proceeding northward there is a Crag pit, now little worked, just at the back of Aldborough, in which the following fossils are found : —

Ballast-pit {near the gas-works), Aldborough.

Abra. Buccinum undatum.

Cardium edule. Littorina littorea.

Cyprina islandica. Purpura lapillus.

Lucina borealis. Trophon antiquum.

Mactra oralis. Turritella communis.

— subtruncata.

Mya arenaria. Balanus crenatus.

Mytilus edulis.

Pecten opercularis. Large double shells of Mytilus edulis are not uncommon in this pit.

Pectunculus glycymeris.

Tellina obliqua.

— praetenuis.

A slight cutting on the railway one mile N. of Aldborough passes through a thin bed of Red Crag with an abundance of Tellina, Mactra, and Cardium. And in a cutting by the side of the road to Saxmundham, on the hill one mile from Aldborough, Mr. Evans and myself have collected the following species : —

Roadside one mile west of Aldborough.

Cardium edule. ? Clavatula linearis.

Leda myalis. Nassa.

Lucina borealis. Natica hemiclausa.

Mactra ovalis. Purpura lapillus.

Mya truncata. Scalaria clathratula (large).

Mytilus edulis. Turritella communis.

Pecten opercularis.

Tellina obliqua. Balanus crenatus.

— praetenuis.

Calyptreea chinensis. Echinocyamus pusillus.

In addition to these, Mr. Fisher mentions Buccinum undatum.

These few lists will serve to show the shells generally most common in the Suffolk Crag pits.
