for animals. Tlic first portion of the work, dealiui^ with 

 names given between tlie years 1758 and 1800, was published 

 ])y the Cambridge University Press in 1902, and is well 

 known to all systematic workers as a mine of information 

 about the earlier names in zoology. The present is the first 

 instalment of the second portion of the work as planned, 

 and deals with all the generic and specific names which 

 appeared between 1801 and 1850. The earlier part of 

 Mr. Sherborn's work was carried out with the support 

 of the British Association, with occasional assistance from 

 the Royal Society and the Zoological Society. From 1912 

 onwards, the Trustees of the British Museum have found 

 the modest sums required to carry on the work, and now it 

 has been compl-eted we may perhaps express our profound 

 gratitude to the compiler, and our appreciation of the 

 enormous amount of labour entailed in the completion of 

 his task. 



Following the explanatory introduction is a modest list 

 covering one and a half pages of " libri desiderati " — works 

 which Mr. Sherborn has been unable himself to consult ; and 

 then follows the bibliography of the works which he has been 

 able to consult, occupying one hundred and seventeen pages. 

 This is one of the most valuable parts of the work, as the 

 dates of publication have been most carefully investigated 

 and are given often with short but very useful comments. 

 Finally, a commencement is made with the Index itself. In 

 this the generic and specific names are arranged alphabetically 

 with full reference and date of publication. 



The work is very well printed by the Cambridge University 

 Press for the Trustees of the Museum and is singularly 

 clear and easy to read, and should find a place on the 

 book-shelf of every worker in Systematic Zoology.
