Mr. Wood’s original collection has been enlarged by the accu- 
mulation of specimens since 1835; but very few additional 
species of Foraminifera have occurred to him in his continued 
examination of the Crag of Sutton and elsewhere. Many of the 
forms met with by Mr. Wood have also been found by us in 
miscellaneous hand-specimens of Crag; and we have also some 
additional forms from these sources. We have taken about 
twenty forms (mostly common) from hand-specimens of Crag in 
which the Cardita senilis abounds, and nearly as many (mostly 
the same) from Crag with Cyprina Islandica: the former (Car- 
dita) is very abundant at Sudbourne, Mr. Wood informs us, and 
is not wanting at Ramsholt; the latter (Cyprina) prevails at 
both places in company with the Cardita. Some half a dozen 
forms we met with in a piece of Crag with Ostrea; but these 
are not uncommon forms. Specimens of Bryozoan Crag have 
afforded a dozen forms, mostly common in other varieties of the 
Crag. Specimens of Crag from Sudbourne, Aldberough, and 
Gedgrave have also yielded us a few Foraminifera, but, as in our 
other gatherings, with a paucity of individuals and poverty of 
size and variety that are strongly contrasted with the conditions 
under which Mr. Wood found his numerous and large specimens 
in the Crag of Sutton. On this subject Mr. Wood has remarked, 
in letters to us dated March 11th and August 5th, 1863 :—* It 
is pretty nearly as you suspect: those fine specimens were from 
a special bed, which was at one time particularly rich in those 
remains; and nearly the whole of what I then considered my 
fifty species were obtained from the Crag at one locality in the 
parish of Sutton. This spot, which formerly yielded to my ex- 
amination specimens by hundreds (indeed, I may say by thou- 
sands), now scarcely supplies me with any. As this locality 
fails to furnish me with any but the commoner kinds of shells 
and Foraminifera, I imagine that the rich community must have 
nestled in a protected nook, out of the reach of the moving 
waters, or in some quiet place under specially favourable condi- 
tions, and that the excavations in the deposit, as they have been 
extended westward, have passed beyond this particular habitat. 
The bed at Sutton seems to have been a bank something like 
the ‘Turbot-bank,’ about five miles south of Larne. The Crag 
at Sutton is somewhat isolated now, and separated from that at 
Ramsholt probably by denudation. At the latter place the 
White or Lowest (‘ Coralline’) Crag is overlain by the Red Crag; 
but at Sutton it has been excavated by denudation, and the Red 
Crag abuts against it, as has been pointed out by Lyell (Mag. 
Nat. Hist. new ser. vol. i. 1839, p. 314). Most of my speci-
