Miliolina agglutinans d’Orbigny sp., plate IX. fig. 7. 
Quinqueloculina agglutinans d’Orbigny, 1839, Foram. Cuba, 
p. 168, plate xii. figs. 11—13. 
It is, perhaps, worth noting that this variety has only before been 
found in the fossil condition in the Post- tertiary clays of Norway and 
the west of Scotland. It is a scarce form in the Gault, one example 
only having occurred in each of the levels in which it is found. 
Zone xi., 55 ft. from the top ; 20 ft. ; and 12 ft. 
Miliolina Ferussacii d’Orbigny sp., plate IX. fig. 8. 
Quinqueloculina Ferussacii d’Orbigny, 1826, Ann. Sci. Nat., 
vol. vii. p. 301, No. 18 ; Modele, No. 32. 
The Gault specimens are very variable, but can be readily assigned 
to this species. The figure is from a good type specimen, the variation 
tending towards depression of the ribs. In its occurrence it shows 
a tendency to supersede M. venusta, as it increases in frequency to- 
wards the top of the Gault, whilst M. venusta becomes less common. 
This variety appears in zone xi., 45 ft. from the top, very rare ; 
35 ft., rare ; 12 ft., very common ; 6 ft., common. 
Miliolina tricarinata d’Orbigny sp., plate IX. figs. 9 a and b. 
Triloculina tricarinata d’Orbigny, 1826, Ann. Sci. Nat., vol. vii. 
p. 299, No. 7 ; Modele, No. 94. 
Hitherto this species has not been obtained from any formation 
earlier than the Eocene. Found in zone xi., 45 ft. from the top, 
rare ; 30 ft., very rare.

This interesting Foraminifer resembles Comuspira in external 
appearance, but when rendered transparent the Spiroloculine arrange- 
ment of the later segments can be clearly made out. Zone iv., very 
rare ; zone xi., 55 ft. from the top, rare ; 40 ft., rare ; 35 ft., very 
rare.
