I.—Nores on THE INVERTEBRATE FAUNA OF THE UITENHAGE SERIES 
In Care Cotony.

(Communicated by permission of the Director of the Geological Survey 
ot Cape Colony.) 
IY\HE rich invertebrate fauna of the Uitenhage Series has long 
attracted attention, owing to the conspicuous nature of some 
of its components and the divergence of opinion which has arisen 
in the various attempts to bring it into correlation with Secondary 
faunas in the European area. A recent examination of the fossils 
collected from the Uitenhage Beds by the Geological Survey of Cape 
Colony has afforded an opportunity of reconsidering, in the light of 
extended knowledge, the conclusions of those who have previously 
studied this question of correlation. A comparative study of the 
fauna, with an account of some new species, based principally upon 
the materials collected by the members of the Survey, will shortly be 
contributed to the fourth volume of the ‘‘ Annals of the South African 
Museum”; but in the meantime, the following brief notes, in which 
are embodied some of the principal results, may be of interest to a wider 
circle of readers. 
The most comprehensive »ublished accounts of the Uitenhage Beds, 
including the results of the recent surveys, are those written by 
Mr. A. W. Rogers and Professor E. H. L. Schwarz.’ As regards the 
affinities of the marine fossils, the view that these indicate a Lower 
Cretaceous age has been most convincingly upheld in the paleontological 
studies of Krauss and Neumayr,? whose opinion is the one which is 
now most widely accepted. Sharpe and Tate,? on the other hand,
