were placed 2 of an inch, and in the male 1} inch, in advance of the orbital ring; but 
the sinuses or sacs themselves lay in the broadish and moderately excavated infraorbital 
fossze. 
“Fach foot, as in the sheep, possesses an interdigital sac about 14 inch in depth, and 
opening by a narrow constricted aperture at its front and upper part. The orifice is 
hidden by very short closely placed yellowish hairs, whilst below these the sac is super- 
ficially covered by a tuft of much stronger and longer hairs. The secretion derived 
from these interdigital bags is yellow and of a hardish ceruminous character. 
“On the anterior aspect, but slightly to the inner side, of each fore knee is a small 
dermal gland, or a thickening of the cutaneous tissues, covered by a brownish patch of 
firm hairs. 
“Tn the inguinal regions of both sexes bare oblong or lozenge-shaped spaces exist ; 
each of these is 5 inches or more in extreme long diameter. Upon these inner edges in 
the female the imperfectly developed udders and four teats are situated.” (P.Z.S. 
1870, p. 500.) 
The Saiga is represented in the British Museum by a mounted pair from 
Sarepta on the Volga, and by other skins and skeletons from the same locality. 
There are also some horns obtained by Dr. O. Finsch on the steppe near 
Saisan, on the Russo-Chinese frontier, in 1876 (see Finsch, ‘ Reise nach West- 
Sibirien im Jahre 1876,’ p. 193). 
Our figure of the Saiga (Plate XLIX.) has been put upon the stone by 
Mr. Smit from a black-and-white sketch prepared by Mr. Wolf for the late 
Sir Victor Brooke. The original sketch, which belongs to Sir Douglas Brooke, 
has been kindly lent to us for examination. We regret to say, however, that 
we have no particulars as to the individual from which Mr. Wolf’s drawing 
was taken.
