LIFE = HISTORIES OF 



AFRICAN GAME ANIMALS 



By THEODORE ROOSEVELT and EDMUND HELLER. 

 With Maui/ Illustrations and 40 Fauna.l Main. 2 Vols. 42s. net. 



Theodore Roosevelt has used the greater part of his leisure time in the last several 

 years in the preparation of this splendid work. He has produced it jointly with Edmund 

 Heller, of the scientific department of the United States National Museum, who accom- 

 panied him on his famous African expedition. 



The general plan of each chapter is first to give an account of the Family, then the 

 name by which each animal is- known — English, scientific, and native; then the geo- 

 graphical range, the history of the species, the narrative life-history, the distinguishing 

 characters of the species, the coloration, the measurements of specimens, and the Localities 

 from which specimens have been examined, accompanied with a faunal map. 



It is one of the most important works in natural history and the only comprehensive 

 work of this kind in the African field.
