NOTES AND QUEETES.

These pebble-beds are exposed in the open cutting at the south end of 
the new raihray tunnel, but no fossils are seen in this section. In the in- 
terior of the tunnel, however, the lower portion of the deposit consists of a 
fine light-coloured pebbly sand and a band of hard conglomerate, both of 
which abound with a very fine species of Pectunculus (P. brevirostris); well 
? reserved. Together with this shell are others, some of which belong to 
iOndon Clay species, others are those of the Woolwich and Thanet sands 
series, and several are, I am inclined to believe, undescribed. 
The following are those which I have been able to name with tolerable 
certainty : — Ostrea Sellovacina, O. tenera, Card'ium Pliimsteadlense, C. 
Laytoni, Corhula Begulhensis, C.Arnoiddii, Ci/rena cuneiformis, C. cordafa, 
C intermedia, Cj/f/ierea, ModiolaMitchellii, Pectunculus brevirosfris (very 
abundant). Area, Avicula, Nucula (new species), Cerithium funatum, 
C. JBoR'€7'banJcii, C. Lunnii, Calyptrcea trochiformis. Auricula pycjmcea, 
Fusus latus, F. gradatus, Melania inquinata, Murex, Melanopsis bucci- 
noides, Natica glaucinoides, 3". subdepressa, ^s'eritina globula, Odostomia, 
PseudoUva semicostata, Pitharella RicJcmanii, Ringicula turgida, Torna- 
tella, Troplion subnodosum, Valvata, Serpula, Lamna. To these I add, 
with some doubt, Sanguinolaria Fdicardsii, Anomia, Fusus tuberosus, 
Scalaria SoicerbanJcii, Neritina concava, Eulima or Rissoa. I also add, 
on the authority of my friend Mr. C. J. A. Meyer, Lucina, Tellina, 
Teredo, Melania (? new species), Melanopsis anciUaroides, Scalaria 
(?new species), Fusus (? new species), Turritella, Otodus. 
My friend Mr. Bott possesses a fine specimen of Pholas from this spot. 
A few weeks since I directed the attention of Mr. Edwards to this lo- 
cality, and as that gentleman appears to be much interested in these 
fossils, proper notice will doubtk^ss be taken of any new species. 
A deposit of pebbly sand is evidently the production of water having 
considerable transporting power. It is therefore not surprising to find, 
that since the most abundant fossils are of marine species, those of a fresh- 
water or estuarine character, such as Cyrena, Melania, Pitharella, etc., 
are much waterworn. The relative position of this bed is not shown in the 
sections now exposed, as the pebble-beds extend to the top of the hill. It 
is, I believe, about 60 feet above the Chalk, from which fact, and also from 
the general character of the beds, I feel inclined to place it at or near the 
top of the Woolwich series of l)eds, and not far below the Loudon Clay. 
This is the position assigned by Mr. Prostwich to the conglomerate bed in 
Suudridge Park. 
It will also be interesting to state that the long tunnel at Sevenoaks, on 
the same line of railway, cuts through the Neocomiau or junction beds be- 
tween the "Weald Clay and the Kentish Eag. At the south end of the 
tunnel clay and stone, with Cyrena, Paludina, etc., are seen in the spoil- 
heaps around the shafts. Following the tunnel to the north (the line of 
the dip of the beds), clays with Cerithium appear, which are succeeded by 
more sandy beds abounding in marine fossils, ^rcrtJ?aj<//?u'/, PernaMulletii, 
Corbula elegans, etc. 
Above this bed is a thick deposit of Kentish Eag and Hassock. I hope 
on a future occasion to be able to furnish you with a list of the fossils from 
this bed. — Yours truly, Caleb Evans.
