METER PTJNF1ELD SECTION. 



"3 



lines of cleavage. I obtained here also, from a fallen mass of clay- 

 stone a few specimens of Cyrena *. 



The strata between the hard bands G and E of section fig. 1, 

 were again too closely covered by vegetation to afford an insight into 

 their real condition. They appeared to be mainly argillaceous, but 

 of this I am far from certain. 



The hard band E of section fig. 1 stands out in the cliff at the 

 distance of from 15 to 20 feet beneath the so-called " marine band." 

 It consists of a double layer of semi-indurated or concretionary sand- 

 stone, more or less ferruginous in colour, and passes upwards, 

 within two or three feet, first into sandy clay, and then into stiff, 

 greyish clay, D, which I described in my former paper as representing 

 the " Lobster-clay " of Atherfield. 



On picking into this clay-bed D with a small pointed hammer, I 

 presently obtained traces of marine fossils, Area and Exogyra. Con- 

 tinuing the search downwards into the sandy clay just above the 

 hard band E, I found these marine fossils to be extremely abundant. 

 In about half an hour I had before me, to my great delight, the casts 

 and impressions of a number of undoubted Lower Greensand fossils. 

 Although few of these retained the shell, the species were, with two 

 or three exceptions, easily recognizable. The following list sufficiently 

 indicates their character : — 



Fossils from beneath the " Lobster-clay " at Pwifield. 



Terebratula sella, Sow. 

 Anomia laevigata, Sow. 

 Exogyra Boussingaultii, D' Orb. 



Tombeckiana, JJ Orb. 



sinuata, Sow., var., = E. aquiia,

 Cytherea parva, Sow.

 field). 



Prevosti, D'Orb. 



Solecurtus Warburtoni, Forbes. 

 Thetis laevigata, D' Orb. 

 Trigonia (Atherfield species). 



(Atherfield species). 



Venus, sp. 



Three or more species indeterminable. 



Here, then, was at last the clearest evidence which could well be 

 required as to the correctness of the views expressed on this subject 

 in my former paper. These fossils are the common species of the 

 Atherfield clay. They come in at Pun held, as elsewhere, beneath the 

 "Lobster-clay" and above the "shales with Cypris" of the Upper 

 Wealden ; and although the " Perna-bed " has not as yet been found 

 at Punfield, there is now 1 think but little doubt of its ultimate dis- 



* The species here mentioned as occurring in and beneath tbe grit-stone are 

 Cypridea tuberculoid, Sow., C. valdensis, Sow., and Cyrena media, Sow., which 

 are, by the way, tbe common species of the Upper Wealden. Is it not possible 

 that Fitton's specimens of CypHs and Cyrena were also obtained from this 

 horizon ?
