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 very 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 shoul- 

 der-stripe. Mr. Blyth has seen a specimen of the hemi- 

 onus 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 

 BO 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 in- 

 stance in a chestnut: a faint shoulder-stripe may some- 

 times 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
