INTRODUCTION. 



placed first ; while works the dates of which cannot be ascertained, MSS. and original 

 drawings are put last. Successive editions of a work immediately succeed the first, and 

 translations follow the original work. The serial publications of Societies, etc., precede 

 any separate works issued by them, while the titles of Maps are put at the very end of 

 the heading to which they belong. 



Titles in Russian and Servian characters have been transliterated on the system adopted 

 some years ago by the Museum in association with the principal scientific societies, and 

 published in "Nature," Vol. XLI, February 27, 1890, pp. 396-7. Titles in Japanese 

 characters have been transliterated by Prof. R. K. Douglas or by members of the Japanese 

 Embassy, to whom also the Editor is greatly indebted for the appended translations. 

 Translations are also given of the titles of works written in Russian, Polish, Hungarian and 

 other Eastern languages, and in this matter the Editor has to thank members of the staff of 

 the Printed Book Department of the British Museum for their help. 



In addition to the indispensable assistance rendered by members of the staff whose 

 names are given in the Preface, the editor has received very considerable aid from 

 many colleagues. He desires more especially to express his obligations to Mr. G. A. 

 Boulenger and Mr. G. C. Crick for the great help they have given in reading the proofs, 

 as well as to Dr. F. A. Bather for co-operation with respect to Swedish titles. To Mr. C. 

 Davies Sherborn the Editor is peculiarly indebted : all the valuable bibliographical data 

 brought together by him, in the course of his work on the " Index Animalium," having 

 been freely made available for the purposes of this Catalogue, in which much of the 

 information so obtained now appears for the first time.
