GLOBIGERINA CAMBRICA, 0. sp. Pl. I., figs. 5 @ to ec. 
See “Phosphate Nodules” Pl. 1, figs. 8 and 17; Pl. 3, fig. 8? 
Multilocular, variable in the position of the first chambers. 
Sometimes two of these are visible within the final chamber, 
and one without, in other cases all three (or four?) are external 
to the final chamber. 
Sculpture. The surface is marked with numerous minute 
pits, only visible with a strong lens. 
Size. Diameter including the final chamber 1 to 13 mm. 
Horizon and locality. As the preceding. 
This species differs from the more modern (Pliocene) Globi- 
gerina conglomerata, Schwager, in the fact that the chambers do 
not connect with each other, and there is not the same grada- 
tion of size in the chambers. No more than four chambers have 
been observed in this species, dnd when they are all external they 
are frequently found detached from the final cell, leaving a cup- 
shaped depression on its surface. The final chamber is always 
much larger than the others. 
GLOBIGERINA GRANDIS, n. Sp. Pl. fig, 6. 
Sculpture. As in the preceding species. 
Size. Diameter 2 mm. 
Horizon and locality. As the preceding. 
GLOBIGERINA DIDYMA, Nl. Sp. Pl. I., figs. 7 a and b. 
I 
See ‘‘ Phosphate Nodules, (Pi iets: L-and.42. Pl 2. fio: 9. 
Multilocular, probably consisting of four chambers, of which 
the two final ones are of nearly equal size. There is an arched 
mouth at the edge of the final chamber, on the opposite side 
from that whereon the small primary chambers are situated. 
Sculpture. As the preceding. 
Size. Diameter, short 14 mm.; long 1#mm. 
Horizon and locality. As the preceding. 
GLOBIGERINA TURRITA, n. sp. Pl. L, figs. 8 a and b. 
“Phosphate Nodules ” p. 114, Pl. 3, figs. 5 and 7 
Multilocular, cells linear in arrangement; or iearhy so, regu- 
larly increasing in size. 
Size. Length 14 mm.; width nearly 1 mm. 
Horizon and locality. Shales of Assize 2 in. Band b. Scarce. 
This form was obtained by W. D. Matthew in sectioning 
phosphate nodules.
