PREFACE. Vli 



works of reference as the British Museum Catalogues 

 of Birds, by Dr. Bowdler Sharpe, and those of Reptiles, 

 Amphibia, and Fishes, by Dr. Giinther and Dr. 

 Boulenger. The valuable works en Mammalia by 

 Sir W. Flower, Mr. Lydekker, Mr. Grev, and Dr. 

 Trouessart, were indispensable to me. 



To Sir William Flower, Mr. Lydekker, Professor 

 Sars, and Professor Smitt, I am especially indebted 

 for allowing me to reproduce drawings from their 

 works, and to my friend Mr. Welch for some beauti- 

 ful photographs. The Council of the Royal Irish 

 Academy also kindly gave me permission to reprint 

 the maps used in illustration of my paper. Professor 

 Haddon first suggested my writing this book, and 

 gave me many useful hints ; and great assistance was 

 rendered me by my colleague, Mr. G. H. Carpenter, 

 in revising the proofs. To both of these kind friends 

 I desire to acknowledge my deep sense of gratitude. 



R. F. SCHARFF.
