This characteristic Cretaceous form has been recorded from various 
horizons in the Chalk of Bohemia (Reuss) ; and from the Chalk of 
England (Rupert Jones), and of the North of Ireland (Wright). 
Many of the Gault specimens are distinctly curved in the line of 
growth. It is found in zone v., very rare ; zone vii., very rare ; 
zone ix., very rare ; zone x., very rare ; zone xi., 55 ft. from the 
top, common; 50 ft., rare; 45 ft., rare; 35 ft., frequent; 30 ft. 
very rare; 25 ft., very rare; 20 ft., very rare ; 12 ft., very rare; 
6 ft., very rare. 
Nodosaria ( D .) paupereula Reuss, plate IX. figs. 13, 14. 
Nodosaria paupercula Reuss, 1845, Yerstein. bohm. Kreideform.,

Mem. Soc. geol. France, ser. 3,vol. i., No. 5, p. 43, pi. ii. fig. 17 a , b . 
This somewhat variable species is well distributed in the Gault. 
It is also found in the Chalk of Bohemia (Reuss) ; and the Gault of 
France (Berthelin). At Folkestone it is found in zone i., specimen 
b, very rare ; zone ii., specimen b , very rare ; zone iii., rare ; zone iv., 
common ; zone v., common ; zone vii., frequent ; zone ix., frequent ; 
zone xi., 12 ft., from the top, frequent ; 6 ft., very rare. 
Nodosaria (Z>.) Fontannesi Berthelin, plate IX. fig. 15. 
Dentalina Fontannesi Berthelin, 1880, Mem. Soc. geol. France, 
ser. 3, vol. i. No. 5, p. 42, plate ii. fig. 14. 
This form, which has been described from the French Gault, is 
found at Folkestone in zone ii., specimen a, rare ; zone iii., frequent ; 
zone iv., rare ; zone v., very rare ; zone vi., rare ; zone ix., very 
common ; zone x., very common ; zone xi., 55 ft. from the top, very 
rare; 50ft., frequent ; 35 ft., frequent; 12 ft., frequent. 
Nodosaria ( D .) obscura Reuss, plate IX. fig. 16. 
Nodosaria obscura Reuss, 1845, Yerstein. bohm. Kreideform., 
pt. i. p. 26, plate xiii., figs. 7, 8, 9. N. obscura Burrows, Sherborn 
and Bailey, 1890, Journ. Roy. Micr. Soc., p. 557, plate ix. fig. 24. 
The above name can be conveniently applied to those strongly 
costate forms of Nodosaria, in which the septation is imperfectly 
defined on the surface of the shell. This species has been previously 
recorded from the Gault of Folkestone and the Upper Greensand of 
Warminster (Rupert Jones) ; the French Gault (Berthelin) ; the 
Red Chalk of Speeton (Burrows, Sherborn and Bailey) ; from the 
Greensand of the Gault of the Rhine, and in various Cretaceous strata
