the London clay with a thin bed of Oldhaven pebbles resting on 
clayey Woolwich and Reading beds, the upper part of which contained 
Paludina rock. Specimens of Unio, Cyrena, Ostrea, Cerithiwm, 
Hydrobia, &., were found. Pitharella rickmani was also discovered 
in this cutting for the first time. 
April 25th.—The members of the Society, on Saturday afternoon, 
joined the Geologists’ Association, under the guidance of Mr. W. 
Whitaker, F.R.S., and Mr. A. E. Salter, F.G.S., in an excursion to 
Loam-pit Hill, Lewisham. The day being fine, a large party of the 
two societies assembled. The first pit visited showed the junction of 
the Woolwich and Reading beds with the Thanet sand, the surface of 
the latter being considerably eroded, whilst cutting into both was a 
terrace of Thames gravel, which probably contained flint implements, 
but there was not sufficient time to search for them. The next pit 
seen contained the upper beds of the Woolwich and Reading series, 
including a bed of oyster-shells nearly two feet thick, overlying a bed 
of Cyrena, in which latter one of the party was so fortunate as to find 
some turtle-bones. Mr. Whitaker having explained the section, a 
third pit was visited, where the lower beds of the London clay con- 
taining Ditrupa were seen resting upon the Woolwich beds. Several 
other pits were visited, showing sections of London clay and Woolwich 
beds, which the Croydon members were able to compare with the 
same deposits in their own neighbourhood. The party then went to 
the Horniman Museum, where they partook of tea, and subsequently 
examined the exhibits. 
May 9th.—The members of the Society joined the Geologists’ Asso- 
ciation in a visit to Crayford and Erith, for the purpose of inspecting 
the gravels and brickearths of that district. Fortunately the weather 
was favourable until late in the afternoon, and the party escaped the 
severe hailstorm which fell in other places. Under the guidance of 
Messrs. W. Whitaker, F.R.S., and A. E. Salter, F.G.S., the party had 
a good opportunity of examining the gravel known as the Dartford 
Heath gravel; also some of the brickearths in pits, which have become 
historic from the mammalian remains discovered in them, as well as 
flint implements, which latter have been fully described by Mr. F. J. 
Spurrell. After partaking of tea at Erith, the party separated, having 
spent a very interesting afternoon. 
June 6th.—An excursion was made to Mr. Brown’s clay-pit, Earls- 
wood Common, to see a section in the Atherfield clay, from which the 
following specimens have been obtained :—Cephalopoda: Nautilus, Be- 
lemnites. Gasteropoda: Aporrhais Robinaldiana, Turritella. La- 
mellibranchiata: Venus vectensis, Cyprina angulata, Cytherea parva, 
Astarte striato-costata, Panopea plicata, Solen, Trigonia Ethe- 
ridgui, Mytilus lanceolatus, Kxogyra sinuata, Perna Mullettii, 
Pecten interstriatus, ? another species, Anomia levigata, Gervillia 
anceps. Brachiopoda: Terebratula sella, Rhynconella, ? latissima. 
Annelida: Serpula. Coelenterata: Astrocenia decaphylla. 
June 23rd.—A visit was paid to the Croydon Gasworks, under the 
guidance of Mr. H. D. Gower, when Woolwich and Reading fossils 
were found on the spoil-heaps, viz. Ostrea tenera and bellovacina, 
Cyrena cordata and cuneiformis, Cerithium funatum, and Melania 
inquinata. 
October 21st.—Under the guidance of Mr. Hogg, twelve members of 
the Section visited Mr. Iles’s gravel-pit at Mitcham, in which remains
