Koulan \Kou"lan\, n. [Native name.] (Zo["o]l.)
A wild horse ({Equus, or Asinus, onager}) inhabiting the
plants of Central Asia; -- called also {gour}, {khur}, and
{onager}. [Written also {kulan}.]
Note: It is sometimes confounded with the dziggetai, to which
it is closely related. It is gray in winter, but
fulvous in summer. It has a well defined, dark, dorsal
stripe, and a short, erect mane. In size, it is
intermediate between the horse and ass.
