d’Orb. (v.t.); C. sulcifera Reuss (v.r.); C. atalica (Defr.) (v.r.) ; 
C. gibba d’Orb. (f.); C. complanata Reuss (v.r.); Polymorphina 
fusiformis (Roem.) (f.); The commonest species are Anomalina 
ammonoides (Reuss) and Globigerina cretacea d’Orb., which outnumber 
all the other species put together. Mr. Hollis has prepared a series 
for the Bucks County Museum at Aylesbury. 
Upper Portland—Long Crendon. A cream-coloured marl, locally 
known as “‘ Wychert ”’ or ““ Witchet ’’, was examined, but yielded no 
Foraminifera. Ostracods are plentiful. 
Kimmeridge Clay (latissima-beds)—Stewkley. Dark shale which 
could not be satisfactorily broken up. No Foraminifera were found. 
Kimmeridge Clay (virgula-beds)—Brill. A small sample of the 
clay sent to the writer contained a few Foraminifera, but the relative 
abundance cannot be judged on such scanty material. The following 
species occur: Haplophragmium sp.; Nodosaria raphanus (Linn.) ; 
Vaginulina harpa Roem.; Cristellaria italica (Defr.); C. crepidula 
(F. & M.); C. rotulata (Lam.); Pulvinulina sp. Dr. A. Morley 
Davies’ has noted Foraminifera from this locality, but they were 
not identified specifically. The five species fully identified above 
occur also in the Hartwell Clay. 
Oxford Clay (pre-cordatum zone)—Quainton Road Junction. 
A sandy clay containing much quartz yielded abundant Foraminifera. 
The list of species is given in full, as the Oxford Clay forms do not 
appear to have been recorded previously.

GENERAL CONCLUSIONS. 
The Foraminifera from the Hartwell Clay above described com- 
prise thirty-seven species belonging to thirteen genera, and may 
be tabulated as follows :—
