438 MAMMALIA OF INDIA. 
The lower part of the forehead at the nasal suture, and the whole 
of the frontals, are more raised and convex than in either O. cycloceros 
or O. Vignei. 
The frontal ridge between the bases of the horns is less developed 
in O. Blanfordii, and in this latter the posterior convex margin of the 
bony palate is differently shaped, being more pointed, and not nearly 
semtcircular as in O. cycloceros.” 
The dimensions of the skull are given in detail by Mr. Hume in the 
paper above quoted, out of which I extract those of the horns :—

The horns of a specimen of O. cycloceros of about the same age were 
29°5 in length and to inches in circumference at base, so that the 
greater length and slenderness of the horns of Ovis Blanfordii are 
apparent. Mr. Hume writes to me that there is a living specimen of 
this sheep at present in the London Zoological Gardens.

Native Names.—Lurhel, Buroot, in the Himalayas ;. Napu, Na, or 
Sna, Thibet and Ladakh ; JVervati,in Nepal. Wa’ or War on the Sutlej. 
Hapirat.—This animal has a wide range; it is found from Sikim, 
and, as Jerdon says, probably Bhotan, right away through Thibet, as. 
Pére David found it in Moupin, and it extends up to the Kuenluen 
mountains north of Ladakh, and in Ladakh itself, and it has been obtained 
by Prejevalski on the Altyn-Tagh, therefore the limits assigned by 
Jerdon must be considerably extended. 
DescripTion.—General colour a dull slaty blue, slightly tinged with 
fawn ; the belly, edge of buttocks, and tail, white ; throat, chest, front 
of fore-arm and cannon bone, a line along the flank dividing the darker 
tint from the belly ; the edge of the hind limbs and the tip of the tail 
deep black; horns moderately smooth, with few wrinkles, rounded, 
nearly touching at the base, directed upwards, backwards and outwards, 
the points being turned forwards and inwards. The female is smaller, 
the black marks smaller and of less extent; small, straight, slightly 
recurved horns ; nose straighter. The young are darker and browner.
