C. REID—PALAEOLITHIC DEPOSITS AT HITCHIN. 
without much boiling and crushing. Leaves seem to be few and 
badly preserved, the fragments obtained being those of the oak 
only. Amongst the seeds and fruits the following are additions 
to the former list:— 
Nympheea alba, L. 
Stellaria media, Cyr . 
Heracleum Sphondylium, L. 
Arctium Lappa, L. 
Carduus nutans, L. 
Lapsana communis, L. 
Sonchus arvensis, L. (?) 
Leontodon hirtus, Z. 
Solanum Dulcamara, Z. 
Mentha aquatica, Z. 
Prunella vulgaris, Z. 
Stachys palustris, Z. 
S. silvatica, Z. 
Alisma Plantago, Z. 
Zannichellia palustris, Z. 
Scirpus fluitans, Z. 
and an undetermined species of Cnicus. 
To these may be added winter eggs of the entomostracan Daphnia ; 
statoblasts of the fresh-water polyzoon Cristatella mucedo , Cuv.; 
and a tooth of a vole, according to Mr. E. T. Newton probably 
Microtus arvalis (not M. agrestis). The molluscs, fish-remains, and 
the rest of the plants belong to species already recorded. 
The number of flowering plants identified from Hitchin now 
amounts to 29, and the total from the various deposits of the same 
date scattered over the southern half of England to about 140. 
Much yet remains to be done before we can claim to have a fair 
knowledge of either the fauna or the flora of this interesting period. 
The smaller fossils from the brickyard at Hitchin, especially the 
beetles, deserve more thorough collecting and study; but this 
is not work which can easily be undertaken by anyone living at 
a distance. I would particularly point to the fossil beetles as 
worthy of investigation, for Interglacial deposits in Canada yield 
a very peculiar coleopterous fauna, containing a very large pro¬ 
portion of extinct species. No one, however, has yet thoroughly 
examined the beetles found in the corresponding deposits in Britain, 
though elytra are of common occurrence.
