408 REPORT—1896. 
Mnium ; fragments of stems; species nearly related to M. serratum, but remark- 
able for having single teeth on the leaf margin and not gemminate as usual in 
European species. 
Mnium ; species nearly resembling MW. rugicum. 
He writes that ‘all these seem to point to an origin in open moorland. 
Acroceratium sarmentosum is not now found on our plains, but is mon- 
tane or sub-alpine ; they are known to go very far into Arctic regions.’ 
The 1888 list adds the following species, though we cannot be per- 
fectly sure that they are all from Bed C. They also were determined by 
Mr. Mitten :— 
brachythecium rutabulum, Bruch and Webera albicans, Schimp. 
Schimp. Bryum pallens, Sw. 
Acroceratium cuspidatum, Witt. Mnium punctatum, Linn. 
Philonotis fontana, Brid. 
The animal remains associated with these plants are very few. They 
include only a small indeterminable mammalian bone, some Ostracoda, a 
few beetles, among which Mr. Waterhouse finds Hylesinus fraaini ?, 
some small galls, and six species of freshwater mollusca :— 
Limnza sp. ’ _ Bythinia tentaculata, Wild. 
Valvata piscinalis, Midd. Spherium corneum, Z. 
Ff cristata, Will. Pisidium pusillum, Gmed. 
No implements have yet beep found in Bed C ; but as the pits are in 
the centre of the channel or lake, and no stone over an inch in diameter 
was seen, negative evidence is of little value till the margin and gravelly 
deposits of the same age have been searched. 
Bed D. 
The character of the deposit changes suddenly immediately beneath the 
lowest seam containing Arctic willows, though the abruptness of the change 
is somewhat masked by the inclusion of derived material in the newer 
strata. Bed C rests on a mass of lignite from 1 to 3 feet in thickness, 
This lignite, at the spot where the trial-pit was sunk, evidently repre- 
sents an ancient alder-carr growing in the old channel—just as alder- 
carrs now grow on the marsh-lands throughout the eastern counties. The 
bulk of the deposit is composed of alder-wood, retaining its bark, but 
more or less decayed, mingled with cones, seeds, and leaves of the same 
tree. The lignite contains also other seeds in profusion, but nearly all 
belong to a few swamp-loving plants, such as are usually to be found in 
an alder-carr, or in the pools or sluggish channels that intersect it. 
There is little or no drifted material, and the few plants that did not live 
on the spot are, with the exception of the hornbeam, berry-bearing 
species, the fruits of which are habitually dispersed far and wide by birds. 
Even the winged seeds of the thistle and dandelion, usually to be found 
in ancient alluvial deposits, are missing, and we have an extremely 
restricted flora, every member of which, however, grew in all probability 
within a few yards of the place where it is now found. The whole of the 
thirty-seven species of flowering plants now determined are still living in 
the county. ; 
A few Valvata piscinalis, a Pisidiwm, one or two indeterminable fish- 
bones, and some elytra of beetles are the only animal remains yet met 
with in the lignite. Mr. Waterhouse observes among the elytra some
