lection of fossil mollusks. The Cephalopoda oceupy a room one-half 
the size of the shell gallery and containing 16 horizontal cases ar- 
ranged transversely, while around the entire room are large wall 
eases. The Gastropoda and Pelecypoda occupy one-half of a room 
the same size as the shell gallery, including large wall cases along 
the side (the other half of the gallery being given to the fossil 
Arthropoda, Echinodermata, etc.). Then there is another gallery 
the size of this devoted to the Cephalopoda, that contains special 
collections of historical interest, or collections including a large 
number of types described and figured in standard monographs. 
The principal ones are the collection formed by William Smith, the 
pioneer of geology in England, the Searles Wood collection of Crag 
Mollusea, the Edwards collection of Eocene Mollusca, the Davidson 
collection of Brachiopoda, the types of Sowerby’s “ Mineral Conch- 
ology,” and specimens belonging to the collection of Sir Hans 
Sloane, which was the nucleus of this great Museum. 
There is also a very large collection of fossil Mollusca at the 
Museum of Practical Geology, which contains the material obtained 
by the Geological Survey of the United Kingdom, and here I wish 
to express my sincere thanks to Messrs E. A. Smith, B. B. Wood- 
ward and the officials of the British Museum generally, as well as to 
Messrs G. F. Harris, E. R. Sykes and others, who did so much to 
make my visit to London both pleasant and instructive. 
I spent a few very pleasant hours in Cambridge with Rev. Prof. 
H. M. Gwatkin, who took great pleasure in showing some of his 
rare forms of radule. I cannot describe this collection, and one can 
only wonder at the time and careful work involved in making so 
many beautiful slides. It is undoubtedly the largest and finest col- 
lection of radule in the world. While at Cambridge, I also had the 
good fortune to meet Mr. A. H. Cook, of Kings College, who kindly 
showed me the “MacAndrews Collection.” This is a collection that 
one could spend hours over, instead of the few minutes hastily spent 
in glancing at some of the important groups. The large suites 
showing the shell in all stages of development is a very noticeable 
feature, and shows what a good selection was made of the large 
amount of material evidently obtained by MacAndrew in his exten- 
sive dredgings. Another collection which the museum at Cambridge 
has recently obtained is the “Saul Collection,” made by Miss Saul, 
of London. The collection is noted for its beautiful Cyprzeas. 
Here we see all of those mentioned as being in the British Museum,
