Foraminifera of the Gault of Folkestone. By F. Chapman. 573 
Nubecularia nodulosa, plate IX. fig. 2. 
A free-growing form, having nodulous chambers united by slender 
stoloniferous tubes, and rectilinear in growth. All the specimens 
found are apparently fragments; the longest consisted of four 
chambers. This form resembles in some points N. divaricata Brady ; 
but, on the whole, it appears to be a distinct form, and confined to 
the Gault. The aperture is a simple orifice, and not phialine, as in 
the form described by Dr. Brady. It occurs in zone iv., rare ; zone v., 
frequent ; zone x., rare ; zone xi., 55 ft. from the top, rare ; 50 ft., 
frequent ; 45 ft., common ; 35 ft., common ; 25 ft., common ; 6 ft., 
very rare. 
Sub-family MILIOLIN1NM. 
Biloculina d’Orbigny [1826]. 
Biloculina undulata , plate IX. figs. 3 a and b. 
A form which resembles B. depressa d’Orb. in contour, but with 
both surfaces of the test ornamented with concentric undulating ridges. 
One specimen only, from zone xi., 25 ft. from the top. 
Spiroloculina d’Orbigny [1826]. 
Spiroloculina asperula Karrer, plate IX. fig. 4. 
Spiroloculina asperula Karrer, 1868, Sitzungsb. k. Ak. Wiss. Wien, 
vol. lvii. p. 136, plate i. fig. 10. 
Becorded by Dr. Karrer from the Miocene of Kostej; and by 
Dr. Brady as a recent, comparatively shallow water form. One very 
fine specimen, from zone xi., 55 ft. from the top. 
Miliolina Williamson [1858]. 
Miliolina venusta Karrer sp., plate IX. figs. 5 a and b , and 6. 
Quinqueloculina venusta Karrer, 1868, Sitzungsb. k. Ak. Wiss. 
Wien, vol. lvii. p. 147, plate ii. fig. 6. 
Becorded from the Miocene of Kostej (Karrer), from the London 
Clay of Piccadilly (Sherborn and Chapman), and noted by Dr. Brady 
as an essentially deep-water form. This variety is a very distinct 
one in the Gault series of Miliolines ; with but one exception, how- 
ever, which presents a broader aspect than the type, and of which a 
figure is given. This Foraminifer makes its appearance in the Gault 
in zone x., -where it is very common ; also in zone xi., 55 ft. from 
the top, very common ; 50 ft., very common ; 45 ft., frequent ; 40 ft., 
frequent ; 35 ft., frequent ; 30 ft., frequent ; 25 ft., very common ; 
20 ft., common ; 12 ft., common ; 6 ft., very rare.
