Preface vii 



by himself in Newfoundland during the past season to be 

 added to the series of photogravures. Thanks are also due 

 to Mr. |. Turner -Turner for the loan of photographs of 

 abnormal heads of American deer. 



Since the text was in type a number of colts of Przewalski's 

 horse have been added to the collection at Woburn Abbey. 

 All but one show a distinct white muzzle — a feature incon- 

 spicuous in the older specimen figured in the sequel ; they 

 all have the front surface of the legs, from the knees and 

 hocks downwards, black ; and they neigh very like a horse. 

 They indicate that Equus przewalskii is a distinct species, 

 more nearly related to the horse than to the kiang. It may 

 be added that the tarpan is now said to be extinct, having 

 been exterminated during the sixties. 



It may be noted that in a recent issue of Globus (vol. Ixxx. 

 p. I 88) Dr. Nehring arrives at practically the same conclusion 

 with regard to the relationship of the Bactrian camel to the 

 extinct Russian and Siberian species as is advanced in the 

 sequel.
