impossible. But about the identification of the following six species 

 there can be little doubt, and they are of importance as marking the 

 liorizon : — 



Naculana {Ledci] minima. 



Protocardium turgidiim. 



Corbiila pisum. 



Crassafella sulcata. 



Panopea [Glycimeris] intermedia. 



Calyptrcea aperta. 



The species about which more or less uncertainty exists or which 

 are indeterminable are the following : — 



A7ioinia lineata (?) . 

 Area duplicata (?). 

 Pectunculus [Axincea] dissimilis ('?). 

 Cardium cf . formosiLHi (?). 

 Cyrena cf. crassa (?). 

 Meretrix [Cytherea] cf. inciirvata. 

 Callista [Cytherea] (?) sp. 

 Cardita sulcata {'?). 

 C. (small) sp. 

 CorbidaficHs{'?). 

 - C. cuspidata (?). 



Tellina sp. 

 Turritella sp. 

 Callianassa (?) sp. 



Fragmentary plant-remains are common, and the vertebra of 

 a small fish was also found. 



The beds immediately below the second band of ironstone con- 

 cretions have not so far yielded any recognizable fossils, though 

 many fragments of plants form thin seams ; but about 8-9 feet below 

 it, that is about 20 feet below tlie base of the Highcliff Sands, the 

 following two species were collected in a dark chocolate-coloui'cd 

 clay with grains of glauconite, and traces of other mollusca were 

 noticed at the same time . — 



Mytiliis affinis. 

 Tornatellcea Nysti. 



At the base of the cliffs at the nortii-east corner of the headland 

 dark-greenish and chocolate-coloured clays are exposed at the beach 

 level and for a few feet above it, and these are in places crowded 

 with grains of glauconite and clear quartz. In these beds about 

 30 feet below tlie base of the Highcliff Sands the Echinoid Schizaster 

 Lf Urhani was found. 



The interest of the above-recorded fossils lies in the indication they 

 give of the age of the Upper Hengistbury Head Eeds in which they 

 occur. In the Geological Survey Memoir On the Country around 

 Bournemotdh (Sheet 329), published in 1898, tliese beds (p. 8) are 

 included in the Bracklesham Series. Prestwich in 1848 (op. cit. 

 supra) was inclined to place them in the Barton Series, and the 

 evidence of the fossils which I have collected points to this corre- 

 lation, for there are no definite or characteristic Bracklesham forms, 

 and all the species identified with certaintj- belong to the Barton
