Cretaceous Gastropoda, and Pelecypoda from Zululand. 15 
Griesbach had regarded the first-named Cephalopod as belonging to 
his zone d, which he considered as equivalent to the " Lower 
Greensand" of Northern Europe, or the Utatur beds of India; 
whilst the Puzosia gardeni he placed in his top zone /, which repre- 
sented the "White Chalk, most probably," of Northern Europe. 
At this date Kossmat favoured the idea of a Lower Senonian age for 
this fauna. During 1896," when reporting the discovery of Upper 
Cretaceous rocks at Sofala, I contributed a notice of the biblio- 
graphy of the Cretaceous Conchology of Southern Africa, in which 
I inadvertently attributed to Dr. Kossmat a tabular list of the 
Pondoland deposits which he had cited in his paper of 1894. 
This list was introduced as representing Griesbach's views in 
connection with the zonal divisions of the beds in question and 
their correlation with the Southern Indian Cretaceous, from which 
Dr. Kossmat dissented, he having successfully proved in his memoir 
the fallacy of such a rendering (see p. 14 of present paper) and the 
necessity for recognising the series as of Lower Senonian age. Speak- 
ing of the Cephalopod fauna of this region, on the same occasion, 
Dr. Kossmat t stated that ''not a single species occurs indicative 
of an horizon earlier than Lower Senonian." The mistake here 
alluded to was afterwards rectified by the publication of a " Corri- 
gendum."! Subsequently, when writing on the Pondicherri 
Cretaceous, Dr. Kossmat, § referring again to the Cretaceous of 
Pondoland, states that those beds belong to the Upper Trichinopoly 
and Ariyalur stages of Southern India. 
These views were more or less adopted by M. Grossouvre,|| who 
was of opinion, chiefly from a study of the Cephalopoda, that the 
Pondoland deposits were of Lower Senonian age, resembling in parts 
the Coniacian ; as well as admitting the existence of Upper Senonian 
(Campanian) on account of the presence of Pseitdoj^hyllites indra 
and Gaudryceras kayei. 
Messrs. Eogers and Schwarz IT next give a detailed account of 
their geological examination of the Pondoland Cretaceous deposits, 
quoting the various fossils they collected, which, as a rule, were
