ME. W. K. PAEIvEE AND PEOFESSOE T. E. JONES ON SOME 
From some mounted specimens lent to us by Mr. F. Galton, F.R.S., we may add the 
following notes as to the Globigerince of the North Atlantic. See also Appendix I. 
At 1650 fathoms the deep-sea ooze consists chiefly of Globigerince , many of them of 
large growth (as if well-nourished), thick-shelled and rough, the sarcode remaining 
(brown) in most of the larger shells ; and at the same time there are very many small 
and delicate individuals (just as is the case with other Foraminifera, — minute dwarfs 
accompanying full-grown specimens of one and the same type). With Globigerina at 
this depth occur a rather small Hotalia Beccarii , a very small Bulimina (1), and siliceous 
Sponge-spicules. At 1600 fathoms Globigerince as above, with a small Spirillina. At 
1500 fathoms Globigerince appear as at 1650 fathoms. The thickness of the chamber- 
wall is relatively great. A sponge-gemmule was also found here. 
I)r. G. C. Wallich has well illustrated Globigerina and Orbulina in plate 6 (unde- 
scribed) of the First Part of £ The North-Atlantic Sea-bed,’ 1862. 
Globigerince are (as is well known) among the most characteristic of deep-sea Foramini- 
fera (Abyssina) ; and these form a group that love to live at from 1000 to 2500 fathoms. 
They are Pullenia , Sphceroidina, Globigerina , and its monothalamous congener Orbulina 
The first three are always rare and small in shallow water ; and Orbulina usually has 
similar conditions. 
Cassidulina is also an abyssal form ; but lives well up to 30 fathoms, though in flatter 
and more delicate forms than it has lower down. 
Genus Pullenia. 
Pullenia sphceroides, D’Orbigny, sp. Plate XIV. figs. 43 a, 43 b (Arctic) ; Plate XVII. 
fig. 53 (North Atlantic). 
For an account of Pullenia , one of the deep-sea forms, probably allied to Globerigina, 
though resembling Nonionina , see Carpenter’s Introd. Foram. p. 184 ; it is the Nonio- 
nina sphceroides, D’Orb. Modeles, No. 43, Ann. Sc. Nat. vol. vii. p. 293, No. 1 ; and A. 
bulloides of the same author, For. Foss. Vienn. p. 107, pi. 5. figs. 9, 10, and Ann. Sc. 
Nat. vol. vii. p. 293, No. 2. 
Our figure 43 is of normal shape, but small size, as are all those which we find in the 
Arctic and North Atlantic seas. Another form of Pullenia has the chambers set on 
obliquely (P. obliquiloculata, Parker and Jones, Plate XIX. fig. 4). In the mixed sands 
from Norway Pullenia splicer oides is rather common and small : it is rare and small, 
often very small, at 1776, 2035, 2176, and 2330 fathoms in the North Atlantic; also at 
1203 fathoms north of Newfoundland Bank, and at 200 fathoms on the plateau off 
Ireland. 
Fig. 53 is the Isonionina guingueloba , Reuss, Zeitsch. Deutsch. Geol. Ges. vol. iii. pi. 5. 
fig. 31, an enfeebled, somewhat flattened form, of looser growth than usual. It occurs 
also in the Eocene Clays of Hants and the Isle of Wight (H. B. Brady), in the ‘ Septa- 
rian Clay’ (Eocene) near Berlin (Reuss), and recent in the Red Sea. 
Pullenia sphceroides lives in the Mediterranean, the Red Sea, and South Atlantic at 
from 30-320 fathoms.
