REVIEWS 167 



317, might have been relegated more conveniently to an appendix at the end 

 of the book, while further appendices might have contained the lists of the 

 fauna, avifauna, and flora with their scientific and local names. 



There are several printer's errors which should have been rectified when 

 the proofs were read, and not a few of the scientific names are incorrect. For 

 example, on p. 273 there are no less than three errors. The Cape Hunting 

 Dog is lycaon pictus ; the Wild Cat, F. ocreata ; and the Lemur, galago. 

 On p. 271 the Leopard should be felis pardus ; and on p. 262 the Greater 

 Kudu should be sirepsiceros kudu. 



The idea of faintly impressing the spoor of the animal over the text is 

 an innovation, and should prove very helpful to big-game hunters who are 

 not familiar with the particular species. 



The book is profusely illustrated with the author's own photographs, 

 and these are all excellent and greatly enhance the value of this admirable 

 book. We will look forward to Colonel Statham's next book and trust that 

 he will have better luck with his telephotographs, only three of which are 

 included in this volume. R. E. Drake-Brockman.
