604 [Prac. B.N.F.C} 



A few years ago I received from my friend Mr. William 



Gray, M.R.I.A., a packet of this clay which he kindly collected 



for me on an occasion when he had visited the place, and from 



this sample I obtained a good many species which had not been 



recorded in my previous communication to the Club. The 



clay weighed 4 lb. 6 oz. troy, after washing it to get rid of the 



fine impalpable mud I had 17*2 oz. of sand in the fine sieve, 



and 6*2 oz. of stones and broken Turritellce in the coarse one, 



the stones were nearly all more or less rounded and had no 



marks of striae on them. The floatings that were taken from 



the fine material weighed "03 oz., and in this there were 



estimated to be upwards of 43,000 specimens. Specimens of 



the very rare and lovely Bolwina Beyrichi were not unfrequent, 



they were large in size compared with the other Bolivince, their 



tests were thin and fragile, and only a few of the specimens 



were got perfect. This species has not hitherto been met with 



in British Pleistocene clay, neither has it been found recent off 



our coast. Among the rarer forms found the following may 



be mentioned — Textularia globulosa, Bolivina elegans, Discor- 



bina pustulosa, and Pirtvinulina Karsteni. 



FOEAMINIFERA. 



Bilacidina depressa, I? Orb., one small specimen. 



Miludina seminulsm [Linn.), very common, small weak specimens. 



M. subrotunda (Jllontag.), rare. 



Ophthahmdum carinatum, B. $ W., one small broken specimen.

T. globulosa, Ehr., rare. 



Bulimina pupoidei, J/ Orb., very common. 



B. elegdns, D'Orb., common. 



B. ftisif/rmis, Will., common. 



si. margmaia, D'Orb., frequent. 



B. elcgantissima, D'Orb., common. 



Virgulina ISchreibci siana, Cz., rare. 



Bohvina punctata, D'Orb., very common. 



B plicata, If Orb , very common.

1 . The sieves used for washing the clay were a galvanized wire sieve 16 

 meshes to the inch and a miller's silk sieve 150 meshes to the inch.
