and exhaustive study by Reuss on the Foraminifera of the Hits clay 
and Gault formations, reference to which has already been made ; and 
upon the tables given by Reuss, M. Berthelin has made some interesting 
analyses of the foraminiferal facies of the various divisions of the two 
areas in Germany and France. By the conrparisons there made, 
M. Berthelin found twice as many species of the Foraminifera pass into 
the Upper Cretaceous beds as into the Aptian beds below the Gault. 
Partly coincident in age with the Gault of the above-mentioned 
areas are the Greensands of New Jersey. For our knowledge of the 
Foraminifera of these beds we are indebted to A. E. Reuss,* * * § A. Wood- 
ward,' f and R. M. Bagg.f The last-named author has given a list of 94 
species, in -which some noteworthy forms, usually considered peculiar to 
the uppermost beds of the Chalk in Europe, have occurred. The same 
author has latterly given short lists of the Foraminifera to accompany 
the stratigraphical details of New Jersey, Delaware, and Maryland, by 
W. B. Clark. § 
Of works dealing with the Foraminifera from strata immediately 
below and above the Gault in Europe, it will only be necessary to briefly 
mention some of the more important. To that of Reuss, in which he 
treats of the Hils formation and the Speeton clay of North Germany 
(Aptian), reference has already been made. Dr. R. Haeusler gives the 
species found in the Gault (Aptian and Albian) of St. Croix.|| The 
present writer has described the Microzoa of the Bargate beds (Aptian) 
of Surrey The Foraminifera of the beds above the Gault have been 
elucidated by G. R. Vine,** who has published a list of these organisms 
from the Cambridge Greensand (possibly derived from an equivalent to 
zones x.-xiii. of the Gault) ; whilst the Cenomanian beds of Bohemia 
have received very careful attention from Dr. Jaroslav Perner.ff 
The literature of the Foraminifera relating to the Upper Cretaceous- 
beds of the Turonian and Senonian stages is very extensive, and refer- 
ences to the chief works will be found by consulting the previous parts, 
of this series of papers.
