II. West Harnwam, NEAR SALISBURY. 
The shells mentioned in the following list were procured from 
a Holocene rainwash clearly exposed in the West Harnham Chalk- 
pit. The depth of the deposit varied from 5 feet at the bottom of 
the hill to 2 feet at the top of the pit, which is considerably below 
the summit of the hill. The shells are not plentiful :— 
Arion ater (Linn.). Helix nemoralis, Linn. 
LFelicella itala (Linn.). Axzeca tridens (Pult.). 
THygromia hispida (Linn.). Cecilianella acicula (Mill.). 
Vallonia pulchella (Mill.). Pupa muscorum (Linn.). 
Lelicigona arbustorum (Linn.). Pomatias elegans (Miill.). 
III. Hartroy, CampripGEsHire. 
This place is about 8 miles from Cambridge. The Rector is the 
veteran geologist, the Rey. Osmond Fisher, F.G.S. The shells were 
collected in 1895, 1897, and 1899, from a field opposite the pond, 
and just across the road. Mr. Fisher, on my inquiring in 1895 
about the occurrence of Helicigona arbustorum in his neighbourhood, 
told me that he had seen and taken a living specimen about thirty years 
before. The field has been partly worked for coprolites (Lower Green- 
sand), but the part from which the mollusca came has not been 
disturbed by such operations. The shells are cast out by moles with 
the soil. A small piece of unglazed Romano-British pottery, turned 
on the wheel, gives the date of the deposit, which is interesting from 
the abundance of ZZ. arbustorum in a sub-fossil condition. The 
mixture of fresh-water shells and the number of species of Vertigo 
and Zimax present, including Iflax gagates (Drap.), point to paludal 
conditions which ceased many centuries ago. The species represented 
are :— 
Limax maximus,’ Linn. Helicigona arbustorum (Linn.). 
Limax arborum, Bouchard- Helix nemoralis, Linn. 
Chantereaux. Cochlicopa lubrica (Miill.). 
Agriolimax agrestis (Linn. ). Cecilianella acicula (Mill.). 
Agriolimax levis (Miill.). Pupa eylindracea (Da C.). 
Milax gagates (Drap.). Pupa muscorum (Linn.). 
Vitrea crystallina (Mill.). Vertigo antivertigo (Drap.). 
Vitrea nitidula (Drap.). Vertigo pygmea (Drap.). 
Vitrea radiatula (Alder). Vertigo angustior, Jeff. 
Arion ater (Linn.). Clausilia bidentata (Strom.). 
Pyramidula rotundata (Mill.). Succinea putris (Linn.).? 
Helicella vtala (Linn.). Carychium minimum (Miill.). 
THygromia hispida (Linn.). Limnea truncatula (Miill.). 
Vallonia pulchella (Miill.). Planorbis marginatus (Drap.). 
LHelicigona lapicida (Linn.). Pomatias elegans (Miill.). 
1 Specimen unfortunately lost, but undoubtedly correct, both from its size and having 
the apex at the right upper corner. 
2 Dwarfed variety.
