was published.* His paper is of interest, since he records Mortoniceras 
soutoni from bed 14, which is considerably higher than the basement bed 
from which the Survey had recorded Pseudophyllites indra. Mr. Plows 
also points out that this basement bed " is visible for the whole length of 
exposure at low tide, and is also probably the basement on the right bank 
of the river." f There should then have been no difficulty in identifying this 
basement bed. The writer also agrees with Mr. Plows in considering that the 
fossil contents of these beds could and should be zoned. 
Dr. van Hoepen J is "inclined to regard the Pondoland Beds as of Upper 
Santonian age." But it should be pointed out that the type of Grossouvre's 
Gaudryceras rouvillei,§ which species was cited by Dr. van Hoepen, is from an 
unknown horizon, whereas the very immature specimen of fig. 10, of Upper 
Santonian age, is more depressed than G. sigcau, v. Hoepen. According to 
Dr. van Hoepen, there are also differences in the suture-line. Again, the 
South African species of Schluteria do not resemble the type of Grossouvre's 
Desmoceras pyrenaicum. " Lenticeras " jullieni, Pervinquiere, is not con- 
sidered to be related to the Pondoland genus Spheniscoceras, which has 
priority before Dr. van Hoepen's " Pelecodiscus " ; and " Schloenbachia " 
foumieri, Grossouvre,|| was on a previous occasion characterised by the 
writer as being more nearly allied to Gauthiericeras ^ of the Coniacian. The 
Pondoland deposits, or rather the great majority of the Ammonites, may 
thus still be considered to be of Uppermost Senonian, or more precisely of 
" Campanian plus Maestrichtian " age, as stated in the writer's previous 
accounts, where it was pointed out that the five known zones of this Upper 
Senonian and Maestrichtian probably represent only part of the true 
succession of horizons. The chances, then, are that a fauna like that of 
Pondoland, which does not quite agree with, e.g., either the Upper Campanian 
of Galicia or the Valudayur Group of Southern India, if homogeneous at all, 
may belong to a hitherto unrecognised intermediate horizon or even horizons. 
Perhaps, since non-sequences are possible, these horizons are not even 
consecutive. 
The writer's thanks are due to Dr. A. Smith Woodward and to Dr. F. A. 
Bather of the British Museum, to Mr. Henry Woods of the Sedgwick 
Museum, Cambridge, to Dr. Kogers, to Dr. Peringuey, and to Mr. E. C. 
Chubb for assistance in various ways.
