122 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



jSTear Aldborough the upper division of the Coralline Crag, but 

 with more shells than at Sutton, is alone exposed. It contains casts 

 of Valuta Lamberti, of Cyprina islandica, with specimens of Echini 

 and Crustacea. Of the latter, a beautiful specimen referable, ac- 

 cording to Mr. H. Woodward, to the genus Gonoplax, and probably 

 to G. angulata, Leach, was found by my young friend Mr. Norman 

 Evans. 



At Iken brick-yard and some adjoining pits the same upper divi- 

 sion with Bryozoan remains is found; while in the lower ground, 

 between the brick-pit and the church, and again between the 

 Brick-pit and "Webber's -Whin Earm, the upper bed / of the lower 

 division (which is here more developed than at Sutton, and con- 

 tains some thin seams of hard shelly indurated limestone) crops 

 out. In the numerous pits in the neighbourhood of Sudbourne 

 Church the upper division g is alone exposed ; but it is now rarely 

 quarried. 



In Sudbourne Park there is a pit on the higher ground which shows 

 a good section of the Bryozoa-beds of the upper division ; while a small 

 shallow pit in the low ground close by the Hall has been long noted for 

 the beauty and variety of its fossil shells. Oyprina, Astarte, Oardita, 

 and Terehratula, &c. abound in this pit, which belongs, I think, to 

 part of bed d (see general section, fig. 4).

The well-known pit by the keeper's lodge at Broom HiU, Ged- 

 grave (fig. 5), shows 7 or 8 feet of yellow sands, full of detached 

 Bryozoa, chiefly Fascicidaria and Alveolaria, belonging to the 

 zone e; beneath this are 15 feet of comminuted shells, interca- 

 lated in which are seams of large shells in a fine state of preserva- 

 tion. In the lower part of this pit, some of the semiindurated 

 seams, when broken open in the plane of bedding, are found studded
