PREFACE xi 



ward, F.R.S., I owe, amongst other things, the recommendation 

 upon which the Trustees of the British Museum gave me the 

 necessary leave of absence. To Sir Henry Tichborne, Captain 

 W. H. Harris, and Mr. J. Benett-Stanford, I am grateful for 

 many acts of kindness when with them in East Africa, and 

 for a generous present of stores from those of the abortive 

 expedition. I must express my best thanks to Mr. J. R. W. 

 Piggott and Dr. Macdonald for hospitality during my two 

 stays at Mombasa, and to Captain Rogers, Mr. C. W. Hobley, 

 Mr. George Wilson, Mr. Ainsworth of Machakos, Mr. Watson 

 of Kibwezi, Mr. Hall of Fort Smith, for help which removed 

 many difficulties from my path. I must also thank those of 

 my colleagues who have worked out the collections brought 

 home, viz. Dr. A. Giinther and Mr. G. A. Boulenger, Dr. A. 

 G. Butler, Mr. E. A. Smith, Dr. R. Bowdler Sharpe, Professor 

 F. Jeffrey Bell, and Mr. Oldfield Thomas, who have described 

 respectively the fish and reptiles, the lepidoptera, mollusca, 

 birds, land Crustacea, and mammalia. New species of plants 

 have been described by Miss A. L. Smith, Mr. Spencer Moore, 

 Mr. E. G. Baker, Mr. A. B. Rendle, and Dr. Rudolf Schlechter, 

 and lists have been contributed by Mr. J. Britten and Mr. A. 

 Gepp. I must also thank Mr. G. R. M. Murray and Mr. C. 

 E. Fagan for their interest in the Expedition, and Mr. C. J. 

 Gahan for his help in connection with the questions concerning 

 Plata nigrocincta (pp. 273-275), and Mr. E. G. Baker, who has 

 read through the proof of Chapter XV. 



I have also received much valuable assistance in the prepara- 

 tion of this book, which I gratefully acknowledge. Mr. J. Benett- 

 Stanford has kindly lent me the negatives from which Plates 

 Nos. H.-VH. and XVIH.-XX. have been prepared. Mr. Hallam 

 Murray has taken great trouble in making from my rough sketches 

 the admirable drawings of the Kedong and Hohnel Valleys, and
