Chap. V.] ANALOGOUS VARIATIONS. 199 



like those on the legs of the zebra : it has been asserted 

 that these are plainest in the foal, and, from inquiries 

 which I have made, I believe this to be true. The stripe 

 on the shoulder is sometimes double, and is verv variable 

 in length and outline. A white ass, but not an albino, 

 has been described without either spinal or shoulder 

 stripe : and these stripes are sometimes very obscure, or 

 actually quite lost, in dark-coloured asses. The koulan 

 of Pallas is said to have been seen with a double shoulder- 

 stripe. Mr. Blyth has seen a specimen of the hemionus 

 with a distinct shoulder-stripe, though it properly has 

 none ; 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 

 distinct 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 ; I have 

 myself seen a dun Devonshire pony, and a small dun 

 Welsh pony has been carefully described to me, both 

 with three 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 this breed for the Indian 

 Government, a horse without stripes is not considered
