The Cambridge University Press have the pleasure to 
announce that they have undertaken the publication of the 
first volume (1758—1800) of Mr C. Davies Sherborn’s Index 
Animalium. 
The objects of this work are :— 
(a) to provide Zoologists with a list of all the generic 
and specific names that have been applied by 
authors to animals since 1 January 1758; 
(b) to give an exact date for each quotation ; 
(c) to give a uniform quotation for each reference, 
sufficiently full to be intelligible alike to the 
specialist and the layman. 
The work has been conducted in the Geological Depart¬ 
ment Library, British Museum (Natural History), under the 
personal care of Dr Henry Woodward. 
Valuable assistance with the rarer literature has been 
afforded by public and private libraries and zoological 
specialists, both at home and abroad. 
A list of books consulted, with notes as to their dates 
of issue and nature of their contents, will be given, and in 
the first volume, at least, a list of species arranged under 
their genera will also be given. 
Volume I will include all references from 1 Jan. 1758 to 
31 Dec. 1800, thus dealing with the rarer literature, which is 
difficult of access, and of vital importance to the consideration 
of the systematic nomenclature of animals, concerning which 
much confusion undoubtedly exists. 
This volume consists of about 1250 pp. and includes 
upwards of 60,000 entries, and is issued at the price of 
twenty-five shillings net.
