In this paper the author described some bones obtained by J. .T. Evans, Esq., in 
tbe lower part of the Oxford Clay at Eynsbury, near St. Neot’s. They consisted of 
thirty-seven vertebrae, twenty-one of which äre cervical, and apparently complete 
that series. These presented" the characters of tbe cervical vertebrae of tbe typical 
Pliosaurs of the Kimmeridge Clay. The reraains of the pelvis included a pubic bone 
showing a close correspondence in form witb those of the Pliosaurs of the Kimme- 
ridge Clay of Ely, and an ischium. 
3. “ Supplementary Kotes on the Fauna of the Cambridge Greensand.” By A. 
J. Jukes-Browne, Esq., B.A., F.G.S. 
This paper was supplementary to one communicated to the Society by the author 
in 1873. in which he maintained that the Upper Greensand does not extend furtlier 
in a nortli-westerly direction than West End Hill, near Cheddington, in Bucking- 
hamsliire, that the Cambridge Greensand is merely a nodule-bed at the base of the 
Chalk Marl, resting unconformably upon denuded Gault, to the upper part of which 
the greater portion of the fauna belougs, and that the remainder of the Fauna, be- 
longing to the deposit itself, eonsists of species proper to the Chalk Marl rather than 
to the Upper Greensand. The object of the paper was to indicate certain additions 
to, and corrections in, the list of fossils upon which these conclusions were supported. 
The following Gault species were indicated as not previously identified in the Cam- 
bridge Greensand • — Nautilus arcualus, Desh. ; N. ineequalis, Sow. ; Turrilites 
elegans, l)’Orb.;? T. Einer icianus , D’Orb. ; Ornithopus histocheila, Gardn. ; Rrachy- 
storna angularis, Seeley; Turbo Bictetianus , D’Orb. ; Pleurotomaria regina, Piet. & 
Roux ; ? P. Itieriana, Pict. & Roux ; Poeten Raulinianus, D’Orb. ; P. subaeutus, 
D’Orb. ; and Lima Rauliniana , D’Orb. The author described as new species : 
Turrilites nobilis, Nautilus , sp. nov., Natica levistriata, Nerita nodulosa, and Lima 
interlineata, and noted several corrections in the nomenclature adopted in his 
former list.

THE FOSSIL FLORA OF THE TERTIARY BEDS OF BOURNEMOUTH. 
Sie, — As Mr. Gardner adinits that the Vegetation of the Bourne- 
mouth beds is drifted, the question seeins to resolve itself into one of 
extent. This he thinks he can measure, and pronounces to be very 
limited. I, on the eontrary, venture to doubt that there is anything 
in the state of this Vegetation repugnant to its having travelled various, 
and in some cases considerable, distances. He insists that the leaves 
have never been drifted from afar, because of their perfect condition, 
and because they are often adherent to the twigs ; and he adds that 
“the forms of most temperate aspect are best preserved, so that, to be 
logically applied, the Drift theory requires the palms, etc., to have been 
drifted upwards.” Now I fail (and I think that your readers will fail 
also) to perceive anylogic in the matter. Short tributaries descending 
from elevated regions at no great distance would necessarily have a 
very swift current ; and the vegetable spoil of those regions would in 
consequence be carried für more quickly, and in better condition, 
towards the place of its deposit than would much of that carried by 
the main river and by those tributaries which flowed with more 
sluggish currents through longer tracts of low ground, and brought 
“ the palms, etc.” 
klr. Gardner, after intimating that I appear to be totally un- 
acquainted with the subject, observes that the Fauna of the Thanet 
sands, Woolwich beds, London Clay, Bracklesham, Headon, Bembridge, 
and Hempstead beds , 1 make it plain to us that the climatal conditions 
1 Tbe Hempstead beds are not usually regarded as Eocene.
