With Plates VI and VII. 



'"THE Pondoland Cephalopoda, first described by Bailey 1 and Gries- 

 bach 2 , were revised by Mr. Woods 3 in 1906, and some additional 

 Ammonites, all of the Indo-Pacific type ( Phylloceras, Lytoceratids, 

 Madrasites) have lately been recorded by Dr. van Hoepen. 4 The 

 collection of Pondoland Cephalopoda in the British Museum, referred 

 to by Kossmat 5 includes further new forms, and in an unfinished 

 MS., the late Mr. G. C. Crick, dealt with most of them. These were 

 briefly mentioned in a paper by the writer on " Cretaceous Cephalopoda 

 from Zululand," 6 and comparison there is made between the 

 Umkwelane Hill fauna, also apparently of Campanian age, and the 

 Pondoland Ammonites. 



The specimens from the Umzamba Beds of Pondoland here 

 described, form part of a collection made by Mr. E. C. Chubb and 

 Mr. W. J. Plows in July, 1919, and include still a further number 

 of new forms, also some Ammonites, like A. sugata, Forbes, and a 

 Gaudryceras, resembling G. sacya (Forbes) auct., that are of interest 

 on account of their range in time. It must be left for future, careful, 

 zonal collecting to establish, more definitely than is possible at 

 present, that the whole of the 20 feet of Pondoland deposit is of 

 uppermost Senonian age, and that no pre-Campanian beds are 

 present.
