PATTISOX— LAXD SURFACE rXDER^'EAXn THE DEIFT. 207 
the precise age of the formation an open question, and to remain 
satisfied for the present with having arrived at the conclusion that 
the Older Parian deposits in Trinidad, and the rocks of similar age 
in South America, cannot be newer than the Gault. 
List of fossils found bv the Government geologists in the Older 
Parian at Ciimana : — Fteroceras, Ceritliium, TurritelJa, Trigonia suh- 
crenulata, D'Orb., Asfrea Couloni, Area, Cardium, Echinus. 
Those found in Trinidad since the survey, and alluded to in the 
above paper, but not included in the foregoing list : — Belemnifes, Bos- 
tellaria ?* Natica Cytherea ?, Plagiostoma ?^ Pecten alatics I'jf 
Ostrea, 2 sp. 
DESCRIPTIOX OF A LAXD SURFACE UNDERNEATH 
THE DRIFT ON THE COAST OF SUFFOLK; OB- 
SERVED IN 1859. 
By S. R. Pattisox, Esq., F.G.S. 
The low cliffs stretching from Gorleston, south of Yarmouth, to- 
wards Lowestoft, are raainh' composed of boulder drift, and are well 
described by the late Mr. Trimmer in the Quarterly Journal of the 
Geological Society for 1857. As an independent confirmation of his 
observations on the intercalation of the whole boulder-clay double 
series, between the fluvio-marine and forest bed beneath, and the 
local marls and marsh and estuary beds occasionally above, I send 
the following note, made without having had the benefit of Mr. 
Trimmer's paper. 
On the beach under Corton the section is as follows : — 
Feet. 
Mould 2 
Disturbed ferruginous sand 10 
Alternations of gravel and sand, frequently interchanging. 
Gravel well rounded and small. Large masses of dark clay 
entangled in the gravel witli lumps of chalk. Small rolled 
pebbles of chalk, boulders of slate rock, coal-measures, green- 
stone, red sandstone, oolites (very abundant), having an 
avernge depth of 30 
Clean brown sand, with occasional very small pebbles .... 40 
An irregular bed of peat, surface and contents of marshes, com- 
pressed rusli-like plants matted together, and much mine- 
ralized with sulphate of iron 2 
An irregular surface below the bog, covered witli roots and lower 
portions of stems of ferns (Pteris ?) in situ, in a dirt-bed ; oc- 
casionally large trees 5 
Dark clay, with a greenish tinge, underlying tlic heath-like de- 
* Perhaps the Pteroccias of the Geological Suney. 
t Possibly an Avicula.
