Vol. 50.] ON THE PUKTSECK BEDS OF THE VALE OP WARDOER. 61 



in the dark shale. Nothing like Cypridea fasciculate occurred in 

 any of the beds. 



The dip being steep, it is not surprising to find that a great 

 thickness of Upper Purbeck clays comes in to the eastward within a 

 very short distance. Three hundred yards north-east of the above 

 section are some cottages, where a well was sunk in 1834. From 

 the account of the well-sinker, and from examination of the material 

 thrown out, this well seems to have proved the following beds : — 



Feet. 



Yellow clay 3 or 4 



Light-grey silty marl 11 or 12 



Stiff grey elay 5 or 6 



Very stiff, grey and brown clays about 20 



Hard gritty stone at the bottom ; this being 



punched through, water rose at once a few inches 



about 40 feet. 



In the material thrown out and coming from the stiff grey clays, 

 one of us found Paludina carinifera, an Unio, some fish-scales, and 

 many Cyprids, the last- mentioned being identified by Prof. T. Rupert 

 Jones as Cypridea punctata and a smooth variety like C. valdensis, 

 Cyprione Bristovii, and Darwinula Jef/uminella. A specimen of the 

 bottom stone-bed was also obtained, and proved to be exactly like 

 the layers of hard calcareous grit seen in the railway-siding ; it also 

 contained O. punctata, and we have little doubt that it is the upper 

 of the two calcareous grits. 



How much farther the Upper Purbeck Beds extend eastward and 

 north-eastward we were unable to ascertain. There are only low- 

 lying fields in that direction, the ground is obscured by a gravelly 

 soil, and the railway passes on to the alluvium. We think, however, 

 that the yellow Wealden Clays come in a very few yards north of 

 the well. 



On the southern side of the river, in a field near Catherine Ford, 

 which is due south of Dinton Station, a shallow well has recentlv 

 been dug (1892) and exposed beds like those seen in the railway- 

 siding, namely : — 



Feet. Inches. 



Loam and gravel 3 



Marl 2 



Dark-grey grit 2 



Grey marly clay 1 



Dark-grey grit 3 



Eed sandy marl 3 



Hard grey marl 1 3

There are three other localities where some of the beds which we 

 have classed as Upper Purbeck seem to be present, but unfor- 

 tunately no clear sections are exposed. One is on the high ground 

 south of the railway-cutting and north-east of Daslett Farm. 

 Another is on the rising ground south of the quarry in the Middle
