.Miss M. E. J. Chandler— The Hordle Marine Bed. 225 



The marine bed occurs as pockets, composed almost entirely of 

 whole shells or of shell fragments, in the white sands (Fig. 1). The 

 highest pocket was lenticular, about 10 inches deep at the thickest 

 point. There was a similar pocket 6 inches below it, whose western 

 extremity was obscured by much vegetation-clad debris. In the 

 6 inches of sand between the pockets a few scattered marine shells 

 were found. 



The fossils agreed closely with those from the Marine bed in the 

 Keeping Collection, Sedgwick Museum. There could be no doubt 

 as to the identity of the deposits. The following were obtained :— 

 Ancilla huccinoides, Lam. Melanopsis subfusiforinis, Morris. 



[= pyrgota, Edws.] Murex sexdentatus, Sow. 



Balanus unguiformis, Sow. M'/a angustata, Sow. 



Bayania fasciata. Sow. Natica lahellata, Lam. 



Bulla estuarina,^6m%. „ Studer i, Bronw. 



Cancellaria (Bonellites) miiricata, Neritina aperta, Sow. 



Wood. ,, concava, Sow. 



Cardium 1 Nucula deltoidea, Lam. 



Corhula cuspidata, Sow. Odontaspis elegans, Ag. 



Cijrena obovata, Sow. Ostrea velata, Wood. 



,, pulchra, Sow. Paludina lenta. 



Cytherea suhorhicularis ? Pisnnia [Tritonides) labiata, Sow. 



Lepton nitiduluni Wood. Planorbis sp. 



Lucina albella, Lam. Potamides Junatus, Sow. 



Melania acuta, Sow. [= miiricata, ,, fseudo-cinduf!, D'Orb. 



Wood.] Scalaria laevis, Morris. 



These fossils were identified by comparison with the Keeping 

 collection, where they were almost all represented. The only new 

 record of importance was the occurrence of Odontaspis elegans. 

 Marine, brackish, and freshwater fossils occurred side by side, 

 and the shells were mostly so crushed and worn that the larger ones 

 were hard to obtain entire. 



A glance at the table on p. 224 shows that eastwards the white 

 sands attain a greater development, but to the west, on the contrary, 

 they diminish in importance and quickly pass above into greenish 

 marls, which include the Limnaea Marl and extend to the base of 

 the gravel. 



The controversies relating to the Marine bed are really concerned 

 with its position in the Hordle cliff-section relative to the Lower 

 Headon Freshwater beds. 



The earlier writers, Searles Wood and Wright (1, 2), believed it to 

 be intercalated between a Lower and an Upper Freshwater Series, 

 a statement disputed later by Tawney and Keeping (4), as it was 

 clear from the descriptions that the Upper Freshwater series con- 

 sisted of the Unio clays and white sands which constitute the highest 

 beds of the Lower Headon Freshwater Deposit. The clue to the 

 situation is, however, furnished by Searles Wood himself, for in his 

 paper he stated that he considered the portion of cliff to the east
