E. Neaverson—Foraminifera of the Hartwell Clay. 459 
A few specimens from Hartwell are referred to this species, 
which is recorded from Upper Jurassic strata of Switzerland 
(Haeusler) and the Gault of Folkestone (Chapman). At the present 
day it lives off the coast of South America, best developed at a 
depth of 1,900 fathoms (Brady). 
Locality : Hartwell (r.).

Several specimens from the Hartwell Clay seem to belong to this 
species rather than to J. albicans. Their colour is brown, their 
shape variable, and the surface bears irregularly disposed perforate 
papille : often two or more chambers are mutually adherent. 
T. papillata is recorded from the Upper Jurassic of Switzerland 
(Haeusler), and at the present day is a deep-water form with a 
world-wide distribution (Brady).

This species was originally described from the Oligocene Septaria- 
clay of Pietzpuhl (Reuss), and Chapman records it from the Gault 
of Folkestone. Ranging from Lias to Recent, it lives at depths 
varying from 129 to 1,900 fathoms in many parts of the existing 
seas (Brady).
