others of our members, and “it may fairly be concluded that 
they came from the Holaster planus zone,’’ which used to be 
classed as the uppermost zone of the Middle Chalk, and not 
with the Upper Chali. 
‘‘That radiolaria existed in considerable numbers in the 
Cretaceous seas is proved by the fact that in the small quantity 
of material examined forty-one species, belonging to twenty 
genera, have been recognized.”’ 
Amongst the most important geological publications of the past 
year is that by A. J. Juxes-Browne, entitled ‘‘ The Cretaceous 
Rocks of Britain. Vol. i. The Gault and Upper Greensand of 
England.’’* 
There are, of course, frequent references to Surrey, and chap. 
vi. (pp. 92-102) is devoted to that county. One misses, however, 
any reference to the Caterham boring, which shows the greatest 
thickness of Gault anywhere except in eastern Sussex, and also 
any notice of the fine new railway-cutting at Merstham. 
In chap. xxvi., which treats of Subterranean Extension, there 
is no reference to one of our deep borings, at Streatham, in 
which both Upper Greensand and Gault were passed through. 
In chap. xxix., on Economics, our building-stones are noticed, 
but Farnham is treated as if in Hants. 
This comprehensive treatise, which is to be followed by other 
volumes, should certainly be in the hands of Surrey geologists. 
During the past year the Geologists’ Association has held five 
Excursions in Surrey, in some of which we joined. t . 
The first was at Wimbledon and Kingston, to see the gravels of 
the high grounds, which were described by Mr. H. W. Moncxron. 
_ The second was to Caterham, Godstone, and Tilburstow, for 
the study of the Upper and Lower Greensands. 
At Guildford, the Reading Beds and the Chalk were seen, the 
sections being described by Mr. Coomara-Swamy, with an analysis 
of ‘‘race’’ from the Reading Beds by Mr. A. C. Youne. 
Then our own Chalk, at Purley, Kenley, and Whyteleafe was 
examined and described by Mr. G. KE. Distey. 
Lastly, Netley Heath and Newlands Corner were visited, 
under the guidance of Mr. W. P. D. Sressine, who describes 
the sands of the former place (resting on the Chalk). Fragments 
of shells of marine genera were found in these, and more have 
been found since, this being the first record of such. Should 
this discovery show that these sands are of the same age as those 
of Lenham, in Kent, the Crag will be claimed as a formation to 
be added to the Surrey list.
