viii PREFACE. 



Mr. A. Sidney Olliff — to whom I am indebted for 

 much careful and very helpful work in this direc- 

 tion — has turned to good account a considerable 

 amount of hitherto unworked material in the collec- 

 tion, chiefly amongst the Coleoptera, adding thereto 

 several new species. Mr. W. F. Kirby has also 

 been unsparing in his valuable and kind assistance. 



The botanical portion of the Appendix has 

 been completely revised by Mr. R. A. Rolfe, who 

 has worked out no fewer than eleven hitherto un- 

 described species of plants, and determined the 

 nomenclature of several others which were left 

 doubtful in the former edition. 



To the natural history illustrations have been 

 added one plate of beetles and three of plants, drawn 

 respectively by Mr. W. Purkissand Mr. W. H. Fitch. 



The list of Native Words and Phrases has been 

 increased by the addition, from one of the traveller's 

 note-books, of a number of words which had 

 previously escaped notice ; the entire list having 

 undergone revision in spelling by Mr. Mackenzie, 

 who has kindly supplied the rules for pronunciation, 

 which will be found set forth in a footnote. 1 



To all the gentlemen above named I must take 

 this opportunity of warmly expressing my thanks 



1 These rules do not apply to native words and names used else- 

 where in the book and in the maps, which have for the most part 

 been spelt on phonetic principles.
