a spoken of are on the southern slopes of
the Thian Shan mountains, which form the boundary between Russia and
Eastern Turkestan, separating the provinces of Semiretchinsk and
Kashghar. The Turgat pass, about 12,760 feet, lies between the
Kashgharian fort of Chakmak and the Russian fort Naryn or Narin.
Captain Trotter mentions in a foot-note that these sheep, as well
as ibex, abound in these hills in such large quantities that they
form the principal food of the garrisons of the outposts. At Chakmak
they saw a large shed piled up to the roof with the frozen carcases
of these animals. (A most valuable map of the country is published
in the 'Journal' with this paper.)

The chief difference between this species and _Ovis Polii_ consists
in the much greater length and divergence of horns of the latter and
the longer hair on the neck.

NO. 441. OVIS BROOKEI.
_Brooke's Wild Sheep_.

HABITAT.--Ladakh, or probably the Kuenluen range north of Ladakh.

[Illustration: _Ovis Brookei_.]

DESCRIPTION.--This species is founded on a single specimen, which,
in the opinion of Mr. Blyth, Mr. Edwin Ward, F.Z.S., Sir Victor Brooke
and others, differed materially from all other wild sheep, but, as
they had only a head to go upon, further investigation in this
direction is necessary. It is not even certain where the animal was
shot, but it is believed to have been obtained in the vicinity of
Leh in Ladakh. It is apparently allied to the _O. Ammon_ of Thibet,
which Sir Victor and Mr. B. Brooke term in their paper _O. Hodgsonii_,
but it differs in its much smaller size, in its deeply sulcated horns,
the angles of which are very much rounded, and the terminal curve
but slightly developed. It differs also from _O. Vignei_ and _O.
Karelini_. The orbits project less, with greater width between them,
the length of the molar teeth also exceeds the others. There are two
wood-cuts of the skull and horns in the 'P. Z. S.' 1874, page 143,
illustrating Mr. Edwin Ward's paper on the subject.

The following are the dimensions of the specimen:--

Inches.
Length of skull 11
Smallest breadth between orbits 4-5/8
Length of horns, round curve 33-1/2
Circumference of horns 13-3/8

NO. 442. OVIS VIGNEI.
_Vigne's Wild Sheep_.

NATIVE NAMES.--_Sha_ or _Shapoo_.

HABITAT.--Little Thibet; Ladakh, from 12,000 to 14,000 feet.

DESCRIPTION.--Genera
