Synopsis
Excerpt from A Monograph of the Foraminifera of the Crag, Vol. 1
In May, 1835, Mr. Edward Charlesworth read before the Geological Society of London a paper "On the Crag of part of Essex and Suffolk" ('Proceed. Geol. Soc., ' vol. ii, pp. 195-6), in which he mentioned that, "for his general information respecting the organic remains in the two beds" of the Crag, he was indebted to Mr. Searles Wood (then of Hasketon, near Woodbridge), whose collection of Crag fossils included "50 species of minute Cephalopods." These are the Foraminifera (at that time regarded generally as microscopic Nautili, &c.) which are brought forward in the present Monograph, to be illustrated, described, and put in comparison with other known Rhizopodal faunas, fossil as well as recent; the whole series having been liberally placed at our disposal.
Mr. Wood's original collection has been enlarged by the accumulation 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 ones 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 (Cardita) is very abundant at Sudbourne, as Mr. Wood informs us, and is not wanting at Ramsholt; the latter (Cyprina) prevails at both places in company with the Cardita. Some half dozen varieties we met with in a piece of Crag with Ostrea; but none of these are uncommon. Specimens of Polyzoan Crag have afforded thirty forms, mostly common in other varieties of the Crag.

Similar conditions are pointed out by the Bivalved Entomostraca of the Crag, the distribution of which will be treated of in an Appendix to this Monograph.
