1 86 Reid— Notes on the Geological History 
Nuphar luteum, Linn. 
Seeds are common in a postglacial river deposit at 
Mundesley, and also in the preglacial Cromer Forest-bed at 
nearly all localities. I have not seen any from interglacial 
beds. 
{Nymphaea alba, Linn.] 
Recorded by Heer as occurring in the Cromer Forest-bed at 
Happisburgh. The seeds may have been obtained from a 
recent alluvdal deposit at that locality. No specimens have 
been found in the larger collections made within recent years, 
and I do not know of any trace of this species in Britain in 
deposits older than the recent alluvium. 
Lychnis diurna, Sibth. 
One well-preserved seed from Redhall, and two from Hailes, 
in interglacial beds. 
Lychnis flos-cuculi, Linn. 
Postglacial beds of Garvel Park, on the Clyde, eight seeds 
received from Mr. Thomas Scott. Interglacial beds of Red- 
hall, three capsules and numerous seeds received from Mr. 
Bennie. 
Stellaria aquatica, Scop. 
Three seeds, from the preglacial Cromer Forest-bed at 
Beeston. 
Stellaria media ? Linn. 
A badly-preserved compressed seed, shows concentric lines 
of tubercles becoming obsolete towards the centre, and form- 
ing a double keel on the periphery, as in S', media. Inter- 
glacial, Hailes, near Edinburgh. 
OXALIS ACETOSELLA, Linn. 
One seed. Interglacial, Redhall, near Edinburgh. 
Prunus communis, Huds. 
A few stones. Preglacial (Cromer Forest-bed), West 
Runton, Happisburgh, and Pakefield.
