The ass sometimes has very distinct transverse bars on its legs, like those on the legs of a 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.
