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 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 foals of this species are generally striped on the legs and faintly on the shoulder.
