148 ON THE ORIGIN OF SPECIES 



The koulan of Pallas is said to have been seen with a 

 double shoulder-stripe. The hemionus has no shoulder- 

 stripe ; but traces of it, as stated by Mr. Blyth and 

 others, occasionally appear : and I have been informed 

 by Colonel Poole that the foals of this species are 

 generally striped on the legs, and faintly on the 

 shoulder. The quagga, though so plainly barred like 

 a zebra over the body, is without bars on the legs ; but 

 Dr. Gray has figured one specimen with very distinct 

 zebra-like bars on the hocks. 



With respect to the horse, I have collected cases in 

 England of the spinal stripe in horses of the most dis- 

 tinct breeds, and of all colours ; transverse bars on the 

 legs are not rare in duns, mouse- duns, and in one 

 instance in a chestnut : a faint shoulder-stripe may 

 sometimes be seen in duns, and I have seen a trace in a 

 bay horse. My son made a careful examination and 

 sketch for me of a dun Belgian cart-horse with a double 

 stripe on each shoulder and with leg-stripes ; and a man, 

 whom I can implicitly trust, has examined for me a 

 small dun Welch pony with three short parallel stripes 

 on each shoulder. 



In the north-west part of India the Kattywar breed 

 of horses is so generally striped, that, as I hear from 

 Colonel Poole, who examined the breed for the Indian 

 Government, a horse without stripes is not considered 

 as purely-bred. The spine is always striped ; the legs are 

 generally barred ; and the shoulder-stripe, which is 

 sometimes double and sometimes treble, is common ; 

 the side of the face, moreover, is sometimes striped. 

 The stripes are plainest in the foal ; and sometimes 

 quite disappear in old horses. Colonel Poole has seen 

 both gray and bay Kattywar horses striped when first 

 foaled. I have, also, reason to suspect, from informa- 

 tion given me by Mr. W. W. Edwards, that with the 

 English race-horse the spinal stripe is much commoner 

 in the foal than in the full-grown animal. Without 

 here entering on further details, I may state that I have 

 collected cases of leg and shoulder stripes in horses of 

 very different breeds, in various countries from Britain
