Tributaries of the Manuan Creek. — The deposits of this area 
are thus described by Mr. Anderson on p. 59 of the " Third Eeport " : 
" 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 EhyoHte, which persists right to the source of the creek. 
Below the crossing the right-hand bank is entirely of Ehyolite, while 
on the left-hand bank a small outcrop of fossiliferous Cretaceous 
rocks occurs, which is exposed in a mealie garden belonging to the 
neighbouring kraal. The outcrop is a very small outlier, exposed 
on the slope of the northern bank of the creek, and is completely 
isolated on the Ehyolite. This exposure passes along the north side 
of the creek for a distance of a few hundred yards. The strata, 
as exposed in the cliff, which is about 20 feet in height, consists of 
a dirty grey-brown calcareous sandstone, which contains the chief 
specimens of the Cephalopoda, both Ammonites and Nautili. Below 
this, about 15 feet of shales and marls, chiefly containing Mollusca 
and other forms." The Cephalopoda here referred to have been 
described by Mr. G. C. Crick in Mr. Anderson's "Third and Final 
Eeport" under the sub-title of " The Cephalopoda from the Tribu- 
taries of the Manuan Creek, Zululand." 
Mr. Crick considers these specimens as belonging " to the same 
series of beds as the False Bay fossils," although some "probably 
represent a somewhat higher horizon (possibly Senonian)," whilst 
others " seem to show the existence there of either a lower portion 
of the beds which are exposed at False Bav, or even a slightly lower 
horizon."
