THE CRETACEOUS ROCKS OF BRITAIN. 
Mr . Hill visited the quarry in 1897, and contributes the follow, 
ing noteHere about 110 feet of Turanian Chalk is traversed ; 
about a third of the main face is now obscured bv talus, but smaller 
cuttings to the right and left expose the lower parts. The chalk 
is for the most part soft and white; Hints occur near the top, and 
there is at least one layer of large, massive Hints. Terebratulina 
gracilis var. lata is fairly common, Rpondylus swinosus and Sp. latus 
also occurred, and in a fallen block containing some of the large flints 
a crushed Echinoderm, apparently Ucluster planus , was found. 
FoSSIXiS OF THE MIDDLE CHALK IN SUSSEX. 
The following is a list of such fossils as can at present be referred 
with certainty to the Middle Chalk of Sussex, and to their proper 
zonal horizon. No doubt many of the fossils figured by Mantell and 
Dixon, especially many of the remains of Fishes and Reptills, were ob¬ 
tained from this division of the Chalk, for, as Dr. Barrois has pointed 
out, the zones of Rhynchonella Cuvieri and of Terebratulina seem 
to be rich in such remains along the range of the South Downs. 
But in most cases the describees were content with saying that the 
specimens came from the Chalk Mail, Lower Chalk or Upper Chalk, 
as then understood, and even when the locality was also mentioned 
it is not often possible to ascertain from what zone the specimen may 
have come. 
The reference of the numerous fossils which have been found in 
this county to their proper zone is a piece of work which may be 
commended to the local geologists, for it could not be undertaken 
in connection with this memoir. 
The list now given is based on the following information—(1) The 
species recorded by Professor Barrois in his well-known “ Kecherches 
(2) lists of fossils found by Mr. Maddoek in each zone during his 
residence at Eastbourne; (3) fossils collected for the Survey by Mr. 
Rhodes from localities near Lewes, and identified by Messrs. Shar- 
man and Newton ; (4) fossils found and recorded by Dr. Rowe in 
Proc. Geol. Assoc., Yol. xvi., p. 359 et seq. (1900); (5) those recorded 
by Mr. H. Willett in his “ Catalogue of the Cretaceous Fossils in 
the Brighton Museum ” (1871) as from the Middle Chalk of 
Mailing and Houghton. 
The localities are indicated as follows : e=Beacliy Head, s=near 
Lewes, and a=Amber ley and Houghton. Mr. Willett’s fossils may 
have come from either zone and are entered in a third column.
