G. C. Crick—Cretaceous Rocks of Natal and Zululand. 341 
sandstones which hitherto have proved unfossiliferous; these, and 
similar rocks occurring further to the north at Cape Vidal, Mr. Anderson 
is inclined to think will prove to be of Tertiary age. At many points 
round the edges of St. Lucia Lake and False Bay, Mr. Anderson 
observed low outcrops of horizontally bedded strata, consisting chiefly 
of calcareous marls and sandstones. The few fragmentary fossils 
obtained from these Mr. Etheridge was inclined to refer rather to the 
Tertiary than to the Cretaceous system. Near the northern end of 
False Bay the western boundary of the littoral is formed by the 
Rhyolite of the Lebombo Range, which extends thence northward 
past the Portuguese border; between False Bay and the western 
boundary of the littoral there are several Cretaceous outcrops which 
have yielded characteristic Cretaceous fossils. 
As it is principally with the Cephalopod fauna of these several 
outcrops that the present communication deals, they may be best 
described in Mr. Anderson’s own words. 
‘* The Manuan Creek,' which joins the Umsinene River before its 
entrance into False Bay, has three tributaries, over each of which the 
northern wagon-track passes. Near each of the three crossings 
outcrops of Cretaceous rocks occur containing fossils. The fossils 
from the outcrops at the most southerly tributary are described by 
Mr. R. Etheridge as Part II of the ‘Cretaceous Fossils of Natal,’ in 
the present Report of the Geological Survey (p. 67), under the title of 
the ‘Umsinene River Deposit.’ This name does not describe accurately 
the position of the deposit from which the fossils that are described 
came, but owing to the fact that there are four fossiliferous deposits 
all in a small portion of the Manuan Creek basin, the name ‘Umsinene 
Deposit’ refers to the deposit occurring immediately to the north of 
the crossing of the most southerly tributary of the Manuan Creek. 
The others are at the crossing of the middle and the northern tributary, 
to the east of Crossly’s store, while the fourth locality is near, but to 
the west of, the junction of the Manuan Creek with the Umsinene 
River. 
‘‘'The outcrop of the ‘ Umsinene deposit’ is of limited extent and 
is exposed chiefly in the bed of the southernmost tributary of the 
Manuan Creek, and on the rising ground to the north of it, and it 
again appears where the wagon-track crosses the next spruit to the 
north. ‘The rock is a calcareous, argillaceous, fine-grained sandstone 
of a brownish colour, with fossils scattered sparingly throughit . .. . 
‘« The next deposit occurs on the middle tributary of the Manuan 
Creek to the north. Where the wagon-track crosses this creek the 
rock is Rhyolite, which persists right to the source of the creek. 
Below the crossing the right-hand bank is entirely of Rhyolite, while 
on the left-hand bank a small outcrop of fossiliferous Cretaceous 
rocks occurs.”’ 
‘* The fossils in this deposit,’ says Mr. Anderson, ‘‘are described 
by Mr. G.C. Crick . . . . in this Report under the title of ‘ The 
South Manuan Creek Deposit.’ ”’ 
1 This name is not given in any of the maps accompanying Mr. Anderson’s 
reports, and has therefore been omitted in the map which is reproduced herewith. 
It appears to be the stream, flowing from the north, which joins the Umsinene 
River just before its entrance into False Bay.
