was a male ; it was nearly uuiforni blacky except for a white 

 patch with two black spots on the chest (see PI. XI^ fig, 1), 

 and almost completely hairless. 



The adult dog (PL XI^ fig. 2) has a certain amount of hair 

 on the head over an area extending from between the ears to 

 the nostrils ; also^ a few hairs on the tail and on the feet. It 

 is stated that there are no hairs at all on the body^ except a 

 solitary one on a wart. The individual hairs are blacky tan, 

 or variegated. The variegated hairs are black and tan, 

 the lower third being tan and the rest black, except that 

 sometimes the tip is also coloured brown. It is further 

 remarked that the hair on the feet has lately become grey. 

 Originally there appeared to be no differentiation in the 

 colour of the hair in different parts of the body, while in 

 the case of the hairless duiker such a differentiation did 

 occur. The dog is now nearly ten years old, and measures 

 twenty-five inches from the tip of the nose to the root of the 

 tail, and stands thirteen inches at the shoulder. He has a 

 strong constitution, and has always been healthy. His habits 

 are normal, except that he is particularly intelligent, as is 

 shown by the following incident : The troopers were ac- 

 customed to give the animal beer, for which he developed 

 a liking, and on one occasion, after taking too large a quantity, 

 he became more than ordinarily inebriated and ill, and ever 

 since then he has refused to touch the offending liquid. 



Another point of considerable importance in this interesting 

 case is the fact that the hairless condition is an inheritable 

 character. 



The dog was paired with a pure white terrier, and a litter 

 of four was produced. Two were white, a male and female, 

 with ordinary hair like that of the mother, and two were 

 hairless. The skin of the abnormal hairless pups was white 

 at first, but it gradually became mottled with black; they 

 were male and female, and grew very slowly. The male 

 when a year old had a height of only about eight inches at 

 the shoulder, and the female about six inches. It is unfor- 

 tunate that subsequently these animals were destroyed, as
