prevent a misconception, or at least a misunderstanding- of the 
different forms. I speak of the superficial aspect, and not of the 
microscopical characters given by Mr. Sollas. In fig. 12a, I have 
given a camera drawing of the external of Chamber, fig. 12, 
magnified about 130 times. The fragments are given as arranged by 
the unintelligent sarcode of the animal, the white interspaces show 
where the pieces have been cemented so as to form a chamber. All 
the rest of the chambers are similarly constructed. Fig. 15, repre- 
sents one of the many varieties of this Group, but it will be observed 
that the last chamber is very different from that of fig. 12. — a portion 
of the primary chamber is broken away, but it has never been so large 
and prominent as the species described. Another variety (?) — but of 
which I have my doubts — is given in fig. 16, pi. II. The terminal 
chamber is altogether different from the ordinary run of the 
Trochammini of the Cambridge hoi'izon, and in the third chamber 
from the top, there is apparently a perforated opening. It may be 
that this form is related to, or perhaps a member of the Genus 
Ha/plophragmium of Reuss (Mono. Carb. and Permian. Foraminifera)

There is present in the Greensand material a few specimens of 
Textularia which can hardly be separated from T. agglutinatis, D'Orb. 
I have figured the most characteristic of the forms. 
Locality: Cambridge, Greensand. 
No Foraminifera, excepting Parkeria, is quoted in the Cambridge 
Greensand Hst (Cat. of the School of Mines). Neither are any given 
in the Cenomanian series besides Parheria in Prof. T. Rupert Jones' 
Brit. Mus. Cat.^ p. 9 ; and no mention of Textularia is made in the 
Gault lists of either the School of Mines Catalogue or in that of 
Prof. Jones. In the Turoniau series, or Chalk Marl and Lower 
Chalk, several species are named, but not the above (Catalogue of 
Poss. Foram. Brit. Mus., 1882, p. 10),
