Stather : Fossiliferous Drift Deposits at Kirmington. 17 



A triplex ? Scirpiis maritinms Linn. 



Zannichellia pedunculata Reichb. Scirpus sp. 



Scirpiis setaceiis Vaxxw. Care.v ificiirva hightL 



' The list is a small one, but it indicates estuarine conditions, 

 and sug'g'ests a sub-arctic climate. With one exception the 

 plants are still to be found in the neighbourhood of the Humber ; 

 but one of them, Carex inciirva, \s, a sea-coast sedge not now 

 ranging south of Holy Isle. 



' i\ striking peculiarity of the deposit is the abundant remains 

 of the estuarine sedge, Scirpus mariti?nus, a plant which, grow- 

 ing out of a few inchesjof water, tends to form a thick belt 

 through which few drifted seeds would find their way. In view 

 of the abundance of this sedge in the bed now examined and of 

 the like-growing reed, Phragmites coviviu?iis, in the deposit 

 which I searched some years ago, the small number of other 

 plants yet detected is not surprising. Land plants are only 

 represented by two fruits of Lapsana, perhaps brought by birds. 

 These fruits of Lapsana, as well as those of the sea-aster, are 

 considerably smaller than my recent specimens, but I have not 

 yet had an opportunity of comparing them with fruits of the 

 same species near their northern limit.' 



From the freshwater shell-bed associated with the peat Mr. 

 E. T. Newton has determined Planorhis spirorbis, Bithynia 

 tentaciilata, with probably Caiidona (an Entom.). 



Great Limber Section. 



A boring was also put down under the supervision of Mr. 

 G. W. B. Macturk, who kindly undertook to aid the Committee 

 in this manner, at the Great Limber brickyard, three miles 

 south-east of Kirmington, where there is a further development 

 of warp and sand, believed by Mr. C. Reid to be of the same 

 age as the Kirmington deposit, though no fossils have been 

 found in it. The section seen in the brickyard and proved in 

 the boring was as follows : —
