occur, and seem to me very remarkable.

I will, however, give one curious and complex case, not indeed as affecting any important character, but from occurring in several species of the same genus, partly under domestication and partly under nature. It is a case

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;

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. →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 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
