ON THE INVESTIGATION OF THE JURASSTG FLORA OF YORKSHIRE, 265 
in the Middle Estuarine beds of Eston Hill, one of the northern outliers 
of the Cleveland Hills. J 
The Gristhorpe bed continues to provide interesting forms. The 
excavations which have been carried on this year in Cayton and 
Gristhorpe Bays have resulted in the discovery of several new species. 
Among them is a new type of Ginkgoalian leaf, which has been 
described as Hretmophyllum pubescens, gen. et sp. nov.,* and this 
type has also been recognised at Whitby. A female flower of the 
Williamsonia type, new to England and probably allied to the 
Wieldandiella angustifolia of Nathorst, has been found, also a new 
fern and some seeds and cones of new types. Many specimens of the 
rare species Beania gracilis, Carr., Batera Lindleyana, Schimp., and 
Cladotheca wndans, L. and H., have been found, also some interesting 
forms of Czekanowskia. Material has also been obtained for the study 
of the cuticular structure of the Jurassic Cycadophyta, the results of 
which will be published shortly. 
The experience of the last few years has justified the opinion that 
many new forms might be found by systematic search, even in the 
oldest and most worked localities. During the last three years the 
Secretary of the Committee, aided materially by grants made by the 
Association, has succeeded in obtaining about twenty-two species new 
to the Jurassic Flora of Yorkshire, which will be described in due 
course. 
The Flora of the Peat of the Kennet Valley.—Interim Report of 
the Committee, consisting of Professor F. KnEsne (Chairman), 
Miss M. C. Rayner (Secretary), Professor I’. W. OLIVER, and 
Professor F. EK. WEIss, appointed for the investigation thereof. 
THERE are extensive deposits of peat in the Valley of the Kennet and 
evidence of old peat workings in the neighbourhood of Newbury. 
The peat occurs from four to five feet below the surface and may be 
as much as eight feet below the present dry-weather level of the river. 
It varies in thickness from a few inches to about ten feet. 
The present investigation was undertaken to map the distribution of 
some of these peat deposits and to investigate and report on the plant 
and animal remains which they contain. 
The following data have been obtained :— 
(1) A coarse flint gravel underlies the peat in all the completed 
sections, at depths varying from six feet to fifteen feet. 
This gravel may mark an early type of infilling of the valley, but is 
more probably part of a gravel terrace formed during Paleolithic times 
which has since been buried beneath the rising flood plain. There is at 
present no certain clue as to its age. 
(2) The peat is of the ‘valley’ type, i.e., it includes varying 
amounts of fine silt and contains land and fresh-water shells. It is
