Brown ferruginous loamy 
sand 
Stiff, ferruginous, sandy 
clay of a reddish- 
brown colour 
Ferruginous sandstone 
(incoherent); with 
concretionary nodules 
Red ferruginous sand .. 
The washed residue consists mainly of quartz 
grains, the finer being angular, the coarser 
subangular. 
Sand, angular to subangular; chiefly clean 
quartz with a few jaspery and milky quartz 
particles. 
Sub-angular quartz particles. 
Angular and sub-angular quartz grains.

Hard shelly limestone .. 
Fine sand, angular; coarse sand, with sub¬ 
angular to rounded grains. 
Grains sub-angular to rounded ; chiefly milky 
quartz. 
Fine sand of clear angular quartz ; coarse sand, 
chiefly milky quartz, with some chalcedony, 
grains sub-angular to rounded. 
Quartz grains angular; numerous flakes of white 
mica. 
Chiefly milky quartz particles and occasional 
flakes of white mica.

flakes of white mica.

Yellow and ochreous 
sandy clay 
Green clay with shells 
Numerous foraminifera belonging to the follow¬ 
ing species :— Truncatulina ungeriana, d’Orb. 
sp. ; Rotalia beccarii, L. sp. ; PolystomelUi 
crispa, L. sp. 
The colouration of the clay is due to the presence 
of glauconitic casts, chiefly of foraminifera. 
The fossils found here are :— 
Foraminifera. — Polymorphina elegantis- 
sima, P. and J. ; P. problema, d’Orb. ; Rotalia 
beccarii, L. sp. ; Polystomella crispa, L. sp. 
Anthozoa. — Bathyactis bcaumariensis, Denn. 
Echinodermata. —Fragments of tests and 
spines, indet. 
Polyzoa. —Selenaria marginata, T. W., and 
var. spiralis, Chapm. 
Pelecypoda. —Glycimeris halli, var. inter¬ 
media, Pritchard ; Crassatellites kingicoloides, 
Pritch. ; Corbula coxi, Pilsbry ; C. ephamilla , 
Tate. 
Scaphopoda. —Dentalium australe, Sharp 
and Pilsbry. 
Gasteropoda. —Liopyrga quadricingulata, 
Tate ; Calyptrcea Jcalimncs, Chapm. and Gabr.; 
Eglisia triplicate, Tate sp.; Turriiella pagodula, 
Tate; Marginella wentworthi , T. W. ; M. 
praeformiculc; sp. nov. 
Pisces. —Fish otoliths (teleostean). 
Fragments of hard, glau- Pieces of molluscan shells invaded and partially 
conitic rocks and shells replaced by glauconite. The shells are probably 
referable to Crassatellites. Fragments of rock 
bored by a perforating mollusc, the crypts 
measuring about 4 mm. in diameter.
