N. cylindracea is peculiarly a shorter form in the Gault than from 
the other localities. It usually has from 2-3 chambers, whilst Reuss’s 
specimens had from 3-6. This species has also been found in the 
Red Chalk of Speeton (Burrows, Sherborn and Bailey) ; and in 
various strata of Cretaceous age in Bohemia, and North Germany 
(Reuss). It is found in the Folkestone Gault in zone xi., 50 ft. from 
the top, rare ; 45 ft., rare ; 30 ft., very rare ; 12 ft., frequent.

Nodosaria Jonesi Reuss, 1862, Sitzungsb. d. k. Ak. Wiss. Wien, 
vol. xlvi. p. 89, plate xii. fig. 6. 
This variety is distinguished by the regular increase in the size 
of the chambers, and by the first one commencing with a sharp point. 
The surface of the shell is always extremely polished. It was first 
described by Reuss from the Folkestone Gault, and this is apparently 
the only locality where it occurs. It is found in zone ix., very rare ; 
zone xi., 55 ft. from the top, very rare ; 50 ft., very rare ; 45 ft., 
common ; 30 ft., very rare ; 12 ft., very rare.

This species has been recorded from the Speeton Chalk (Burrows, 
Sherborn and Bailey) ; the Planermergel of Bohemia (Reuss) ; the 
Chalk-detritus, Charing (Rupert Jones); the Pliocene of Italy 
(Silvestri) ; and as a recent form from 129 and 275 fathoms (Brady). 
It occurs in the Gault in zone vii., very rare ; zone xi., 55 ft. from 
the top, very rare ; 45 ft., very rare,

This form is represented by fragments only ; and it was in this 
condition that Reuss found it, in the Senonian of Westphalia. It 
occurs in the Gault in zone ii., specimen b, very rare ; zone iii., very 
rare ; zone xi., 45 ft. from the top, very rare ; 35 ft., very rare.
