G. C. Crick—Cretaceous Rocks of Natal and Zululand. 348 
or Umzamba Beds.! At the mouth of the Boboi River, between the 
Umtamyuna and Umpenyati Rivers, there is a small outcrop of 
horizontal unfossiliferous sedimentary rocks that Mr. Anderson thinks 
is probably a small outlier of the same series of rocks, 
In the boring at the Bluff, Durban, only fragmentary fossils were 
obtained ; no Cephalopods are quoted. In his work on the ‘‘ Pseudo- 
ceratites of the Cretaceous” (Mon. U.S. Geol. Surv., vol. xliv, 1903), 
Professor Hyatt described and figured (p. 86, pl. xi, figs. 2-6) as 
Eulophoceras natalense, gen. et sp. noy., a single specimen, the locality 
of which he gave as Port Natal, South Africa. Mr. Anderson doubts 
the locality given by Hyatt, and says (p. 50): ‘‘ As the presence of 
Cretaceous rocks at Port Natal has only recently been made known, 
and as no outcrops of them occur on the present land surface, it is 
unlikely to have been thrown up from the possible outcrop on the 
sea-floor, and I think it is more than probable that the actual locality 
from which it came was not Port Natal, but probably it was a specimen 
which had been brought to the Port, either from the Upper Cretaceous 
deposits at the mouth of the Umpenyati River, on the south-east 
coast of Natal, or from the Cretaceous deposits on the coast of 
Pondoland.”” This opinion is strengthened by the occurrence of the 
same genus and possibly the same species among the fossils described 
by Mr. Woods from Pondoland. ; 
In Zululand the most southerly outcrop of Cretaceous rocks from 
which fossils have been obtained is at Umkwelane Hill, near Lake 
Isitesa, south of the Umfolosi River. The fossils, which were 
described by Mr. R. Etheridge in the ‘‘Second Report of the 
Geological Survey of Natal and Zululand,’’ 1904, included a few 
Cephalopods, viz., two new species of Placenticeras, an undetermined 
species doubtfully referred to the genus Creniceras, a fragment of 
Hamites, and a piece of Baculites. Comparing the whole fauna 
with that of the Umtamvuna (or Umzamba) Beds in Pondoland, 
Mr. Etheridge says (Second Report, 1904, p. 93): ‘‘ Puzosia Garden, 
Baily, sp., has not been observed in the present collection, nor any 
of the Ammonites mentioned as occurring in Griesbach’s stratum e, 
nor Zeredo-bored wood as in e of the same author. The fauna of the 
Umkwelane Hill Deposit consists, with few exceptions, of bivalves 
and univalves, like that of Griesbach’s stratum 4, and some of the 
species are identical with those met with in the latter. There appears 
to be a close connection between the fossils of the two beds; possibly 
they may be actually on the same horizon.’’ Mr. Woods considers 
the Umkwelane Hill Deposit to be of the same age as the Cretaceous 
rocks of Pondoland, and this opinion is strengthened by the occurrence 
at Umkwelane Hill of an ammonite which the present writer refers 
(Third Report, 1907, p. 228, pl. xv, figs. 9, 9a) to the genus 
Mortoniceras, and regards as being related to Mortoniceras Soutont 
and If. Stangeri from the Cretaceous rocks of Pondoland. 
Although this is the most southerly outcrop of the Cretaceous beds 
in Zululand, they have been met with some 20 miles further south, 
in bores which were sunk to the north of the Umhlatuzi Lagoon close 
1 The present writer has also recognized.(Third Report, 1907, p. 250) from the 
Umpenyati strata an example of Schlenbachia wmbulazi, a species originally described 
from the Pondoland deposits.
