MAMMALIA.

The two other species of sheep described by Severtzoff from Western Turkestan, 0. heinsi 
from near Tokmak, north of Lake Issyk, and 0. nigrimontana from the Karatau or black 
mountains, north-east of the Syr or Jaxartes, are smaller forms, but apparently more nearly 
allied to 0. poll and O. karelmi than to any other species of wild sheep. It may not impro¬ 
bably be found that intermediate varieties occur, and that all these forms of wild sheep are 
merely races more or less completely differentiated. It should also be noticed that not only 
are these closely allied species distinguished on very small data, but that Dr. Severtzoff s ideas 
of specific distinction induce him to class apart forms which other naturalists do not separate. 
The other known Central Asiatic wild sheep of the true Argali type, omitting doubtful 
forms, are O. amnion 1 2 (vera=0. argali? Pall.) formerly inhabiting the Altai mountains and 
Dauria, but now supposed to be almost confined to part of Northern Mongolia, O. jubata 3 4 5 6 
from north of Pekin, 0. hodgsoni 4 (the O. ammon of Anglo-Indians generally) from the Tibetan 
plateau, and O. brookei? of uncertain derivation, besides O. nivicola 6 from Kamtschatka, nearly 
allied to the American O. moniana. O. vignei, 0. gmelini, 0. cycloceros and their allies form 
another group of species found in South-Western Asia and the Mediterranean area.

As pointed out by Jerdon, Blyth appears to have ultimately considered his Ovis burrhel 
identical with 0. nahura , although at first he looked upon it as distinct on account of the 
darker colour and more rounded horns, but these differences are apparently due to age and 
season. 
The name has been spelt in various ways-— nayaur, nahoor , nahur, and nahura. I have 
adhered to the last, because it has been adopted by J erdon and Blyth, and because nayaur, the 
oldest name, was corrected by Hodgson himself. I may add that the name appears to have 
been given altogether in error, for Hodgson in his original paper in the Asiatic Transactions, 
Vol. XVIII, Pt. 2, pp. 133, 134, states that the native name for the Ovis ammon is bharal, and 
for the smaller Himalayan sheep nayaur. In truth, the reverse is the case, as is well known, 
and Hodgson must have confounded the two. Perhaps it would be more convenient to drop
