Foraminifera of the Gault of Folkestone. By F. Chapman. 571 
are also many Inoceramus prisms, a few glauconite grains, and very 
few angular grains of quartz, but no casts of Anomalina. The fol- 
lowing Foraminifera are also met with in the fine washings : — 
Miliolina venusta Karrer sp., frequent ; Textularia pygmsea Rss., 
very common ; Textularia conica d’Orb., frequent ; Bolivina textu- 
larioides Rss., common ; Dentalina communis d’Orb., frequent ; 
Bamulina globulifera Brady, frequent ; Globigerina cretacea d’Orb., 
very common ; and Anomalina ammonoides Rss. sp., very common. 
Zone XL 35 ft. from the top of the Gault. A pale-grey marly 
clay, with 37*58 per cent, of CaC0 3 , and a residuum of sandy material 
per cent, with the brown cylindrical fragments. Microzoa are 
fairly common. The fine washings consist chiefly of Globigerina ; 
with a few angular quartz-grains and Inoceramus prisms ; glauconite 
common in the interior of Foraminifera, but scarce as free casts or 
grains ; a few of the granular casts of Anomalina, and the following 
Foraminifera : — Textularia pygmsea Rss., common ; Bolivina textu - 
larioides Rss., frequent ; Lagena hispida Rss., one specimen ; Lagena 
Isevis Montagu sp., one specimen; Bamulina globulifera Brady, 
frequent ; Globigerina cretacea d’Orb., very common ; and Anomalina 
ammonoides Rss. sp., very common. 
Zone XI. 30 ft. from the top of the Gault. A pale-grey 
marly clay. A residuum of sandy material, If per cent. Microzoa 
are not very common. The fine washings contain a little glauconite, 
a few prisms of Inoceramus, very few angular quartz grains, and the 
following Foraminifera : — Textularia pygmsea Rss., common; Boli- 
vina textularioides Rss., frequent ; Lagena apiculata Rss., one 
specimen ; Lagena Isevis Montagu sp., one specimen ; Polymorphina 
sororia var. cuspidata Brady, one specimen ; Bamulina globulifera 
Brady, frequent ; Globigerina cretacea d’Orb., very common ; and 
Anomalina ammonoides Rss. sp., very common. 
Zone XI. 25 ft. from the top of the Gault. A heavy pale-grey 
marly clay. A residuum of fine sandy material, 4J per cent. 
Microzoa are very common. The fine washings consist almost entirely 
of the shells of Globigerina, with a few glauconite grains, a few 
angular quartz-grains, shell fragments, a very few casts of Anomalina, 
a few prisms of Inoceramus, fish remains, and the following Forami- 
nifera : — Nubecularia nodulosa sp. n., one specimen ; Miliolina venusta 
Karrer sp., rare ; Textularia pygmsea Rss., common ; Bolivina textu- 
larioides Rss., frequent ; Lingulina semiornata Rss., one specimen ; 
Globigerina cretacea d’Orb., very common; and Anomalina ammo- 
noides Rss. sp., very common. 
Zone XI. 20 ft. from the top of the Gault. A dull grey-green 
rock, or argillaceous greensand ; when struck with a hammer pre- 
senting a bright-green surface, due to the fractured particles of 
glauconite. A residuum of a dark-green sand with a few shelly 
particles, 30 per cent. Microzoa are frequent, and spines of Pseudo- 
diadema. The fine washings consist of a little more than one-half
