316 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jan. 3, 



2nd. Across the river, in a brick-field about one mile above Exbury, 

 I found fragments of shells in a similar grey clay, reposing on purple 

 clay. 



3rd. Close to Beaulieu, on the east side of the river, in a brick-field, 

 I obtained the following section : — 



Soil and diluvium ; brown clay, 2 feet ; sandy clay, 3 or 4 feet ; 

 yellow and light-coloured sand. 



The sandy clay contained a seam, three or four inches thick, of very 

 perfect specimens of Cyrena obovata and Melania costata, together 

 wdth a few broken specimens of Cythercea incrassata and an Ostrea. 

 About a foot below this seam of shells was a very thin seam of broken 

 fragments of the same Ostrea and Cythersea. 



4th. About one mile and a half eastward, near the -village of 

 Langley, a brook running parallel to the Beaulieu river affords the 

 following section : — 



Diluvium ; ferruginous clay, 2 or 3 inches ; greenish clay with 

 vegetable impressions, 2 or 3 feet ; sandy loam with vegetable im- 

 pressions ; stiff clay without fossils, 6 or 7 feet ; bed of nodules of 

 ferruginous clay containing casts of LymncEUS longiscatus, Melania 

 costata, a Natica, Cyrena? and a Nucula? The lowest bed seen was 

 a greenish marl with very perfect specimens of Cythercea incrassata. 



5th. About half a mile to the north, on the same brook, I found 

 in an old marl-pit the same green marl with the Cythersea. 



Still further east, about one mile and a half from Hythe, on the 

 road to Eaglehurst, a grey clay used for brick-making is seen covered 

 by a considerable depth of the yellow sand ; but I could not find any 

 fossils in it. 



I suspect these fluvio-marine beds do not extend much further to 

 the north ; for on the opposite side of the Southampton Water, half 

 a mile below Netley Abbey, I found a low cliff consisting of grey sandy 

 clay with marly concretions like septaria, abounding in shells of the 

 genera Turritella, Corhula, PecteUy Pinna, Rostellarial, Fususi, 

 Volutal, Fholadomyal, and no mixture of freshwater shells, — a 

 group which, by consulting Mr. Prestwich's lists of fossils, seems to 

 belong to some part of the Bracklesham Bay series. 



I have thought it worth while to mention the occurrence of these 

 fluvio-marine beds over this tract, as it might otherwise have been re- 

 ferred to the upper and middle beds of the Bracklesham series, to which, 

 judging by Mr. Prestwich's description, they have great resemblance. 

 Both consist of a series of yellow sands overlying purplish clay and 

 greenish sand : and as that geologist has shown that the lower and 

 middle divisions of the series come to the surface at Southampton 

 with a southerly dip, it might have been believed that the district to 

 the south, which I have tried to describe, was part of the middle and 

 upper members of that formation. The fossils, however, indicate 

 that these beds are higher in the series, and make it probable that 

 the upper Bracklesham beds crop out at some intermediate point ; 

 and of this there seem to be indications in the marine beds near 

 Netley Abbey.
