Xxiv INTRODUCTION. 



In concluding these introductory remarks to a volume wliicli has greatly 

 exceeded my original intention regarding its scope, I embrace the opportunity to 

 record my thanks to Dr. Murie for much valuable assistance accorded to me in 

 its progress through the press. During my absence from Europe, he undertook the 

 supervision of the drawing, printing and colouring of the plates which illustrate 

 this volume ; and moreover I had the advantage of his opinion and advice in some 

 anatomical details, and in the identification of certain species. To the artist 

 Mr. Berjeau, who has faithfully reproduced the anatomical features of the objects 

 described and the distinctive characters of the species represented, my thanks are 

 also due. 



I am specially indebted to Dr. Dobson for having undertaken the descrip- 

 tion of the Chiroptera. 



The identifications of the birds were verified by Mr. E. Bowdler Sharpe, who 

 has carefuUy worked out the literature. 



To Dr. Gunther and Mr. Erancis Day I am obliged for their aid in identifying 

 the few fish obtained ; and more especially to the latter Ichthyologist, who favoured 

 me with a list of the fish collected on the Eirst Expedition, and undertook the 

 description of certain species. 



I have also the pleasure to express my thanks to Mr. W. T. Blanford, who 

 described the new species of MoUusca collected on the Eirst Expedition ; and to 

 Mr. G. Nevill for the account of all the species of this group which were brought 

 together on the two Expeditions. 



In the list and description of certain insects, I am particularly indebted to 

 Mr. Erederick Moore ; whilst I have also to acknowledge the assistance of Mr. 

 Erederick Smith and Mr. Maclachlan in the description of others. The late 

 Mr. W. S. Atkinson and the late Mr. Erancis Walker identified and described the 

 new species of those groups, to which they had specially devoted their attention. 



My thanks are due to Mr. J. Wood-Mason for having worked out the Crus- 

 tacea, an account of which originally appeared in the Journal of the Asiatic Society 

 of Bengal. 



I acknowledge with pleasure my indebtedness to Professor A. C. Brown 

 for the opportunity of figuring in this work a series of the ear-labyrinth of various 

 Cetacean genera, taken from casts made by himself. 



To Professors Giinther, Flower, Turner, Schlegel, A. M.-Edwards, and Paul 

 Gervais, I am under great obligations for the facilities they afforded me in 

 examining the collections under their individual charge ; and to Professor Peters for 

 his advice regarding certain species described in this work.
