LAMPLUGH: NOTES ON COAST BETWEEN BRIDLINGTON AND FILEY. 429 
Under Buckton the softer flintless Lower Chalk rises into the 
base of the cliff, which then becomes less nearly vertical. The details 
of this portion of the Cretaceous series have been carefully worked 
out by Mr. W. Hill (see Q. J. G. S., Vol. XLIV., pp. 320 -366 \ who 
shows that the equivalents of the Grey Chalk and Chalk Marl of the 
southern counties may be recognized in it. Several pink bands occur 
in it, and it is in some parts fairly well supplied with fossils. Its 
thickness is about 130 feet. At its base we have the Red Chalk 
proper, or Hunstanton Limestone (the equivalent of the Upper Gault 
of the south of England), which may generally be found on the fore- 
shore and at the foot of the broken cliff at Speeton, just where the 
Chalk escarpment leaves the coast-line. A search in this bed never 
fails to bring to light Belemnites minimus and Terebratula semiglo- 
bosa, with perhaps Avicula gryphwoides ; and beyond this numerous 
other fossils will reward the patient collector. 
Of the Speeton Clays which come out from under the Chalk 
escarpment at Speeton, and form for about a mile a low broken under- 
cliff, it is to be hoped that the members will not see too good 
a section, since this Can usually be obtained only during stormy 
weather, when the beach and the foot of the cliff have been freshly 
scoured by heavy seas, and the slopes swilled by rain. At other 
times the hardened mud-streams and slipping drift-cap make a pic- 
ture of disorder, out of which the casual visitor may well consider it 
hopeless to bring forth order. But in that case let him turn from 
the task for satisfaction to the glorious view over sea and land which 
confronts him. Under favouring circumstances it is quite possible 
to trace out a definite succession of zones, each containing fossils 
proper to it and not found elsewhere, and thus were compiled the 
details of the full section given in my paper on the subject in 
Q. J. G. S., XLV., pp. 575 to 618. 
But if the members cannot see the sequence as there recorded, 
they should, by searching carefully over the clay-slopes, especially 
towards the shore-line under " Black Cliff Ridge " and to the west- 
ward of it (see map above), be able to collect at least a few 
of the characteristic fossils of some of the zones, e.g. — Ammonites 
noricus (= Hoplites amblygonius^, Bel. jaculum, Bel. lateralis, etc.,
