In this paper the author described some bones obtained by J. .T. Evans, Esq., in 

 the lower part of the Oxford Clay at Eynsbury, near St. Neot's. They consisted of 

 thirty-seven vertebrae, twenty-one of which are cervical, and apparently complete 

 that series. These presented the characters of the cervical vertebra3 of the typical 

 Pliosaurs of the Kimmeridge Clay. The remains of the pelvis included a pubic bone 

 showing a close correspondence in form with those of the Pliosaurs of the Kimme- 

 ridge Clay of Ely, and an ischium. 



3. " Supplementary Notes 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 1875, m which he maintained that the Upper Greensand does not extend further 

 in a north-westerly direction than West End Hill, near Cheddington, in Bucking- 

 hamshire, that the Cambridge Greensand is merely a nodule-bed at the base of the 

 Chalk Marl, resting uneonformably upon denuded Gault, to the upper part of which 

 the greater portion of the fauna belongs, and that the remainder of the Fauna, be- 

 longing to the deposit itself, consists 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 arcuains, Desli. ; N. incequalis, Sow. ; Turrilites 

 elegans, D'Orb. ;? T. Emericianus, D'Orb. ; Ornithopus histocheila, Gardn, ; Brachy- 

 stoma annularis, Seeley; Turbo Pictetianus, D'Orb.; Pleurotomaria regina, Yiat. & 

 Eoux ; ? P. Itieriana, Pict. & Eoux ; Pecten RauUnianiis, D'Orb. ; P. subacutus, 

 D'Orb. ; and Lima EauWiiana, D'Orb. The author described as new species : 

 Turrilites nobilis, Nautilus., sp. nov., Natica levistriata, JSferita nodulosa, and Lima 

 interlineata, and noted several corrections in the nomenclature adopted in his 

 former list.

THE FOSSIL FLOEA OF THE TERTIARY BEDS OF BOURNEMOUTH. 



Sir, — As Mr, Gardner admits that the vegetation of the Bourne- 

 mouth beds is drifted, the question seems to resolve itself into one of 

 extent. This he thinks he can measure, and pronounces to be very 

 limited. I, on the contrary, 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 any logic 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 far 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." 



Mr. 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,^ make it plain to us that the climatal conditions 

 1 The Hempstead beds are not usually regarded as Eocene.
