This species is very rare in the Gault, only one specimen having 
been found in the present collection. This specimen is quite typical, 
and possesses the characteristic thin and conspicuously foraminated 
test. 
As a fossil T. lobatula is known from beds as old as the Carboni- 
ferous, and it occurs in nearly all fossiliferous strata of later date. 
Amongst other occurrences it has been previously found in “ the Gault 
of Kent, probably Folkestone ” (Bupert Jones in Topley’s Memoir on 
the Weald, p. 424) ; and has been recorded by Bagg from the Middle 
Marl beds of New Jersey. 
The living specimens of T. lobatula appear to be unrestricted as 
to depth of water, but it attains its best development in fairly shallow 
water. 
At Folkestone this species was found in zone xi., 35 ft. from the 
top.

^ This species is known as a deep-water form from recent deposits. 
Fossil specimens have been recorded from the Lower Greensand 
(Bargate) beds of Surrey (Chapman) ; from the Middle Marl beds of 
New Jersey (Bagg) ; and from the Pliocene strata of Kar Nicobar 
(Schwager). 
T. Wuellerstorfi was found in the Gault in zone xi., 45 ft. from 
the top, very rare ; 35 ft., very rare.

The test of this species is more regularly and completely involute 
than in the other forms of the genus occurring in the Gault.
