THE NAUTILUS. 55 



lectiou of fossil mollusks. The Cephalopoda occupy 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 

 cases. The Gastropoda and Pclrr i/pmhi 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 

 Arthropod a, Echinodermatn, etc.). Then there is another gallery 

 the size of this devoted to the Ceplm/'ipwl,!, 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 

 Mollusca, the Edwards collection of Eocene Mollusca, the Davidson 

 collection of Brachiopoda, the types of Sowerby's " Mineral Couch- 

 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 radulw. 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 raduhe 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 dredgiugs. Anotlier 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 Cyprreas. 

 Here we see all of those mentioned as being in the British Museum,
