volumes. Moreover, the volumes themselves are distributed with so- 

 lavish a hand that any student can obtain them either for the asking 

 or else for a sum so insignificant as to be afforded by the poorest. 



As an instance of the range of subjects we may mention the 

 following, all of which have formed bibliographies or books of 

 reference of the most comprehensive and valuable natui-e : — 



Scudder : Index to known Fossil Insects of the World. 



Marcou : Catalogue of Geological Maps of America (1752-1881). 



Vogdes : Bibliography of Palaeozoic Crustacea. 



The series of Correlation Papers. 



Eecords of North American Geology since 1886. 



The series of Gazetteers of the States. In progress. 



Darton : Catalogue and Index to North American Geology, 1732- 

 1891 ; continued by Weeks, 1892-1900. 



Branner : Bibliography of Clays, etc. 



Knowlton : Cretaceous and Tertiary Plants. 



Weller : Index of North American Carboniferous Invertebrates. 



Schuchert : American Fossil Brachiopoda. 



Gannett : Dictionary of Altitudes in the United States. 



Warman : Catalogue and Index to the Publications of the U.S. 

 Geol. Surv. 



The one before us is not the least of these invaluable books, and 

 it is a pleasure to offer to Mr. 0. P. Hay hearty and sincere thanks 

 for a book which has long been wanted, and which will certainly be 

 of the greatest value to British zoologists. Mr. Hay divides his 

 book into a Bibliography (up to 1900) ; a tabular Key to the 

 catalogue ; a Catalogue (of the genera and species) ; Addenda et 

 Corrigenda ; Index. The whole book runs to 868 pages. The 

 synonymy is compressed into a minimum of space, by an arrange- 

 ment of quotation by which the several papers are referred to by 

 year and page only, the reader having to refer to the Bibliography 

 for the full quotation. This, though a loss of time to the user, 

 seems inevitable now that the subjects have grown to such vast 

 dimensions. The Index is arranged under trivial names, each 

 followed by its generic variant, and thus any specific name can be 

 found without trouble. 



To criticize such a work as Mr. Hay's would not be possible 

 without great trouble ; use only can show whether his work is 

 accurate. However that may be, we have to thank him for his 

 labours, labours rarely fully appreciated by those who find in such 

 books almost half of their own work done for them. C. D. S.
