Index Animalium. C. D. Sherborn, Cambridge, 1902, pp. 1195. 
This is the first section of a work which in its undertaking is a 
monumental enterprise, and which, if completed, will be truly a won- 
derful achievement. The effort contemplates the cataloguing of all 
animal names, whether of fossil or living, that have been applied by 
naturalists. This volume contains the record from 1758 to 1800, and 
hence embraces but very few fossil names. The rest of the record will 
cover, if brought up to date, more than 100 years, and it is quite cer- 
tain, considering the greater number and the greater industry of name- 
makes during the last century, to far exceed the present volume — and 
it will probably more than double the names contaiiied in this volume. 
This work has been in progress since July i, 1890. It has been coun- 
tenanced by the British Association for the Advancement of Science 
which has had a standing committee of co-operation and advice. The 
Association also supported the finances, in which it was aided by the 
Zoological Society and b}^ the Royal Society. The author has con- 
sulted not only English but continental and American works. The 
list of such works, and their authors, occupies 46 pages. The plan of 
the author gives really two indexes, one of all specific names and one 
of all genera. The specific names may have been applied in numerous
