posed in greater part of materials derived from an older gravel, and 

 from shingle-beds of the Tertiary period ; still with a local admix- 

 ture of angular flints and chalk-rubble. 



As well as the few specimens will allow us to judge, this de posit 

 may be correlated with the one at Clacton on the opposite Essex 

 coast*, where also recent marine and freshwater mollusks have been 

 found by Mr. J. Brown, associated together in a deposit underlying 

 the gravel. 



My chief object in making this short communication to the Society 

 is to direct attention to a locality not hitherto noticed, and which 

 I think likely to yield on further examination a far more important 

 series of Pleistocene fossils than those here enumerated, which were 

 procured during two very short visits. 



Note. — I am indebted to Mr. Rupert Jones for the following 

 interesting particulars respecting the microscopic fossils : — 



"The Entomostraca comprise three forms. The first is very 

 abundant ; the other two are very rare : 



Candona torosa, Jones. Cypris gibba, Ramd, A minute undeterminable form. 



** There is also among the minute organisms picked out from these 

 sands one Rhizopod, — a Globiilina. 



'* The Candona torosaf is a minute bivalved Crustacean, inhabiting 

 the brackish-water ditches near Gravesend. It occurs also plentifully 

 in the Grays deposits, in company with other recent and some 

 extinct (?) Entomostraca. Cypris gibbaX is a recent form, very 

 common in freshwater ponds. 



"The Foraminifer (Globulina), by its presence in the deposit in 

 question, may be regarded as evidence of the at least brackish-water 

 character of the Wear Farm sands. Mr. Pickering, who first dis- 

 covered the recent specimens of C. torosa in the Gravesend ditches, 

 found also a Rosalina-like Foraminifer associated with them ; — a 

 parallel to the above. 



" The valves of the Entomostraca are sometimes separate and some- 

 times united. The sand and fine gravel in which these pleistocene 

 fossils occur, frequently contain also numerous minute chalk-fossils, 

 such as Cytherellce, Bulimince, Rosalince and Crist ellaricB, spiculse of 

 Inoceramus shells, &c." 



4. On Land-surfaces beneath the Drift-gravel. 

 By R. Godwin Austen, Esq., Sec.G.S., F.R.S. 



I stated several years since § that the thick gravel-beds of the valley 

 of the Wey below Guildford were underlaid by an old terrestrial 

 surface, indicated by peat, trees, and sedimentary deposits, — that the 

 remains of the extinct mammalia were usually associated with this 



* Also with Grays and Salisbury.
