044 G. C. Crick—Cretaceous Rocks of Natal and Zululand. 
to the mouth of the Umhlatuzi River, as an arenaceous limestone full 
of fossils, which, according to Mr. Anderson, were identifiable with 
some of those occurring in the limestone at Umkwelane Hill. 
Most of the outcrops of Cretaceous rocks in Zululand, from which 
Mr. Anderson collected fossils, are in the neighbourhood of the north 
end of False Bay and St. Lucia Lake, some 40 miles north of 
Umkwelane Hill. The fossils from several of these outcrops have 
been described in the ‘‘ Third and Final Report,’”’ which has just been 
issued. 
Some of these fossils are described by Mr. R. Etheridge under the 
title of the ‘‘Umsinene River Deposit”’; whilst the present writer 
has described ‘‘ The Cephalopoda from the North End of False Bay, 
Zululand,’ and ‘The Cephalopoda from the Tributaries of the 
Manuan Creek, Zululand.’’ 
As already stated, the Manuan Creek, which joins the Umsinene 
River before its entrance into False Bay, has three tributaries, over 
each of which the wagon-track passes. It was, Mr. Anderson states, 
from the deposit occurring immediately to the north of the crossing of 
the most southerly tributary! of the Manuan Creek that the fossils 
described by Mr. Etheridge under the title of the ‘‘ Umsinene River 
Deposit’ were obtained. Referring to this fauna Mr. Etheridge 
says: ‘‘ Only one species can be said to be actually identical with the 
Umkwelane Hill fauna, viz., Adaria (?) Baily, Eth. fil., but as the 
general facies of the Umsinene fossils resembles that of the Umkwelane 
Hill bed, I am induced to regard them simply as horizons in one and 
the same geological series.”” Mr. Etheridge goes on to say: ‘“‘If my 
determinations of these very fragmentary fossils are correct, we find 
in the Umsinene bed four Uitenhage forms”? . . . . and then, 
referring to the Cephalopoda, which include only a few forms, viz., 
Dowvilleiceras (?) nodosum, u.sp., Douvilleiceras sp., Desmoceras sp., and 
Hamites sp., remarks that ‘‘as in the case of the Umkwelane Hill 
fauna there is an entire absence of those species recorded from his 
Umtafuna fauna by Griesbach.” 
Of the Cephalopod faunas described by the present writer in the 
Report, that from the deposit at the north end of False Bay, and near 
the junction of the Manuan and Umsinene Rivers, where from 70 to 
100 feet of strata are exposed, is a particularly rich one, the forms 
ranging in size, according to Mr. Anderson’s statement, from half an 
inch to more than a yard in diameter; it includes the genera 
Phylloceras, Gaudryceras, Tetragonites, Turrilites, Baculites, Enemo- 
ceras(?), Lorbesiceras, Acanthoceras, Desmoceras, Puzosia, and Nautilus, 
with many new forms, the number of forms of Acanthoceras being 
particularly noteworthy. 
Compared with the fauna of the nearest outcrop, viz., that described 
under the title of ‘‘The Umsinene River Deposit, Zululand,” the 
False Bay deposit has not yielded any specimen resembling either 
the Hamite or the examples doubtfully referred to the genus 
Dowvillerceras, but the specimen recorded from the Umsinene River 
1 This tributary is not named in the map accompanying this paper; from 
Mr. Anderson’s description it appears to be the stream which is named the Unywana 
River in the Geological Sketch-maps of Zululand issued with the First and Second ' 
Reports respectively.
