Woodbridge, and from Aldborough, Chillesford, Sudbourn, 
Orford, Butley, Sutton, Ramsholt, Felixstow, and many other 
localities in Suffolk, also from Walton-on-the-Naze, in Essex. 
Ibe specimens so collected were employed by Mr. Searles Wood 
in the preparation of his “ Monograph on the Crag Mollusca,” 
published by the Palasontographical Society (1848-1861) ; with 
supplements in 1871, 1873, and 1879, illustrated by seventy-one 
quarto plates. Each figured specimen is indicated by a small 
green label affixed to it. 
A geological description of the Crag formation by Mr. 
S. V. Wood, jun., F.G.S., and Mr. F. W. Harmer, was issued 
by the Palasontographical Society in 1871 and 1873. 
The collection was presented by Mr. S. Y. Wood to the 
British Museum, January, 1856, and a supplementary collection 
was given by Mrs. Searles Y. Wood in 1885. 
The next “ Palasontographical Collection ” is of nearly equal 
antiquity and fully of equal merit. It is the Eocene Molluscan 
Collection formed by the late Frederick E. Edwards, Esq., 
F.G.S., about the year 1835, and was continually being added 
to, until a few years before his death, which happened in 1875. 
It was acquired for the Nation by purchase in 1873. 
Originally intended to illustrate the fossils of the London 
Clay, Mr. Edwards extended his researches over the Eocene 
strata of Sussex, Hampshire, and the Isle of Wight, where, 
assisted by Mr. Henry Keeping, he made the most complete 
collection ever attempted by any geologist, and it still remains 
unrivalled. 
Mr. Edwards contributed six Memoirs to the Palasonto- 
graphical Society, 1848-1856 ; also separate papers to the 
“ London Geological Magazine,” 1846, the “ Geologist,” 1860, 
and the “ Geological Magazine,” 1865, descriptive of the Eocene 
Mollusca, in his collection. 
Mr. S. Y. Wood continued the work for Mr. Edwards, 
describing and figuring the “ Eocene Bivalves ” in the annual 
volumes of the Palasontographical Society for 1859, 1862, 
1870, and 1877. Each specimen which has been figured is 
specially marked. 
About 500 species have been described and figured, but the 
collection is very rich in new and undescribed forms. 
The last Collection is that of a Naturalist who devoted his 
entire life to the study and illustration of a single class of 
organisms, namely the 13 racin' opoda. It was formed by the late 
Thomas Davidson, Esq., LL.D., F.R.S., F.G.S., Y.P. Pal. Soc., 
etc. (of West Brighton, and Muir-house, Midlothian), between 
the years 1837 and 1886, with the object of illustrating his 
great work on the “ British Fossil Brachiopoda,” published 
by the Palaeontographical Society, in six quarto volumes, 
between the years 1850 and 1886, comprising 2290 pages of text,
