LOWER CHALK — SURREY. 
55 
Holaster subglobosus , Pecten Beaveri, Terebratula biplicata, Ter. 
semiglobosa , fish teeth, all occurred in the lower and greyer part of 
the Chalk. The Belemnite Marls, with some 50 or 60 feet of the 
Lower Chalk, can be seen at Messrs. Farrington’s quarry at Beigate. 
Another fine section through this zone occurs at the Dorking 
Greystone Company’s pit at Betchworth Station. At the time of 
our visit the quarry presented a perpendicular face estimated about 
175 feet, about half of which was in Lower Chalk. At the western 
corner of the quarry fresh workings exposed about 10 feet of the 
Lower Chalk and the Belemnite Marls. The marls here proved to 
be 10 feet thick; at the top was softish grey laminated marl, with 
lenticular beds of hard white chalk ; the basal 8 feet were of solid 
massive character, breaking with well-marked conchoidal fracture. 
The characteristic fossil Actinocamax plenus was common. 
Brockham quarry, which almost joins that of Betchworth, pre¬ 
sents the same features, and has nearly as high a face. 
A similar section occurs at the old Dorking lime works, just north 
of Dorking Station. The Belemnite Marls are seen at the top of this 
quarry, which exposes 70 feet of Lower Chalk, the upper 45 to 
50 feet nearly white, the lower part grey and more marly. 
A long narrow quarry one mile west of Warren farm and 1J miles 
south-east of Guildford, exposes Lower Chalk with the Belemnite 
Marls. The Chalk dips north at a very high angle, and no measure¬ 
ments could be taken. On the south side whitish chalk with 
several impressions of a large Ammonite occurred. On the north 
side there is similar chalk overlain by buff grey chalk with Acti¬ 
nocamax plenus. 
The upper part of the Lower Chalk is exposed again at Seale 
Lime Works; about 35 feet of it are seen below the Belemnite 
Marls, which are here 5 feet thick. 
Again, at the lower Victory quarry, three miles east of Farnham, 
the upper part of the Lower Chalk is seen, but though the 
Melbourn Bock occurs at the base of the upper quarry, and 
only a roadway separates the two pits, the Belemnite Marls are not 
exposed. 
The following list of fossils must be regarded as merely a first 
attempt at a zonal list of the Low r er Chalk fossils of Surrey, for 
though many good fossils have doubtless been obtained at various 
times, the only published list known to us is that by Mr. Caleb 
Evans. It is assumed that most of his “ Lower Marden Park ” 
fossils came from the zone of Am. varians, and to these have been 
added such fossils as were found by Mr. Hill and Mr. G. E. Dibley. 
Localities are indicated thus; 0==Qxted> b — Betchworth and
