shire fossils, was the first, in 1840, to notice this deposit, three 

 years previous to Mr. Wood's visit. At that time Mr. Edwards 

 could trace the bed for 300 yards*. These facts attest the rapid 

 waste going on in this coast. The following list of Testacea is 

 the result of the joint researches of Messrs. Edwards and Wood : — 



Actseon. Melania muricata. 



Ancillaria subulata, Lam. Melanopsis ancillaroides, Desk. 



Area elegans. carinata. Sow. 



Balanus unguiformis. Sow. fusiformis, Sow. 



Bulla (two species). minuta, Sow. 



Csecum. Murex sexdentatus, Sow. 



Cancellaria muricata. Mya angustata, Sow. 



elongata. Mytilus? affinis. Sow. 



Cerithium cinctum. Sow. Natica depressa, -Sow. 



margaritaceum. Sow. epiglottina. Lam. 



terebrale. labellata, Lam. 



ventricosum. Sow. Nematura, n. sp. 



Chemnitzia (two species). Nerita aperta. Sow. 



Corbula cuspidata. Sow. Neritina concava. Sow. 



Cyrena cycladiformis, Desh. Nucula deltoidea, Lam. 



obovata. Sow. , new species. 



pulchra. Sow. Odostomia subulata. 



Cytherea incrassata, Desh. Ostrea.

Melania angulata, fFood. Turbo? 



fasciata. Sow. Voluta spinosa. Lam. 



From that portion of the bed which was exposed, we collected a 

 considerable number of the species of the above list. The shells 

 are not so well preserved as those of the upper marine bed at 

 Colwell Bay, many of them being largely impregnated with the 

 peroxide of iron. The thickness of the bed exceeds that given 

 by Mr. Wood ; but, in other respects, I agree with that excellent 

 observer in regarding it as a true marine stratum intercalated 

 between the stages of the upper and lower freshwater formations. 



The Lower Freshwater Formation. 



No. 5. Dark stifi" clay above, passing into an iron-gray coloured 

 sand below, — the latter richly fossihferous. The dark clay forms 

 a good tracing line of the bed in the cliff, which inclines at an 

 angle of 2°, and can be seen, in situ, with a telescope, from Col- 

 well. It rises on the shore to the east of Hordle-lane End, and 

 crops out about a quarter of a mile east of Mead End. The
