F. FritscJiii ; * * * § and therefore the latter name stands by priority. The 
species has also been found in the Turonian of Bohemia by Perner.f 
Marginnlma aspera.% This name has already been used for another 
type by Ter quern ; § it is therefore here proposed to alter the name of 
the Gault species to asperula. 
Cristellaria nodosa Reuss sp. || Costa has figured a form,^f to which 
Mr. Millett draws my attention; it is comparable to Reuss’s species, 
and has priority of publication. It will be necessary, therefore, to retain 
the form under Costa’s name, as Cristellaria lobata. 
In the table of species, the fistulose varieties of the Polymorphinse are 
denominated by the new names proposed by Prof. Rupert Jones and 
the present writer in a paper on the ‘ Fistulose Polymorphinse,’ published 
subsequently to the descriptions of the fistulose varieties given in this 
work.** 
In the following Tabulation of the Red Chalk Foraminifera (pp. 40- 
42) we have 86 species. Of these 52, or a little more than 60 per cent., 
have been found in the Gault of Folkestone. In the Lower Gault 
(zones i.-vii.) 38 Red Chalk forms occur ; whilst in the Upper Gault 
(zones viii.-xiii.) we find 48 species common to this and the Red Chalk ; 
or 44 per cent, and nearly 56 per cent, respectively. 
As the result of an examination of Chalk-marl from Eastwear Bay 
(Bed ii. of Price), which I have made for this present work, If there are 
only 25 species, or 29 per cent, of the Foraminifera from this horizon, 
common to the Red Chalk. It therefore seems conclusive that the con- 
ditions under which the Red Chalk (speaking of it in a general sense) 
was deposited are nearly the same as were existent during the formation 
of the Upper Gault of Folkestone. There is a marked absence of 
shallow-water and coarsely grown arenaceous Foraminifera in the Red 
Chalk, quite unlike the assemblage found in the Chalk-marl.

tt I have refrained from using the series of Foraminifera from the Chalk detritus 
of Charing for comparison here, as it is possible that there may be fossils from higher- 
horizons included in it.
