340 DR. J. MURIE ON THE [May 26, 
young animal are exhibited in the wall-cabinets of the British 
Museum ; so that little remains to be added on my part. 
Much stress has been laid by Mr. Ogilby* on the presence or ab- 
sence of cutaneous glands as indicative of affinities among the hol- 
low-horned Ruminants. I made a careful search, therefore, for these 
on the dead body of the Prongbuck; and the subjoined is the result: — 
1. No crumen or suborbital sinus was discovered, as all previous 
writers have averred. 
2. There is, however, a cutaneous gland which exudes a yellow 
glutinous secretion, situated an inch and a half below the ear. Dr. 
Richardson evidently alludes to this when he says, ‘‘ there is a 
dark blackish-brown spot at the angle of each jaw, which exhales a 
strong hircine odour’’+. 
3. No inguinal sacs exist, thus verifying Ord{ and Dr. Gray’s§ 
character of the genus. 
4. In a footnote to his paper, Mr. Bartlett|| says, “A gland of 
considerable size exists in the back of this animal, immediately over 
the white patch.”” My examination confirms his observation. Dr. 
Canfield J has even more pointedly referred to this when speaking 
of the glands as “one over the junction of the sacrum with the 
spine, 6 or 8 inches anterior to the tail.” 
5. The last-quoted author, in the living animal, says, furthermore, 
‘the Antelope has a very peculiar odour, strong and (to. some 
persons) offensive. This comes principally from the glands in the 
white part of the breech. One of these is placed over each pro- 
minence of the ischium, below and on each side of the tail;’’ another, 
as above referred to, No. 4. This statement was substantiated in 
the dead body of our animal. 
6. On both hind limbs, at the hock, behind the joint, and rather 
to the outside of the leg, there is another cutaneous secreting-gland. 
7. Interdigital sacs exist on all four limbs. 
The cutaneous glands of Antilocapra americana may be thus ex- 
pressed :—Preseut, in pairs, 1 postmandibular or subauricular, 
1 ischial, 1 hock, 2 interdigital: total 10 glands. Absent (but occa- 
sionally present in other ruminants), suborbital and inguinal. 
In a review of the structures of the Saiga I have shown that the 
hair, among other characters, differentiates it from members of the 
antilopine group, and, so far as hirsute clothing is concerned, 
proves it to be a Sheep. When the same test is applied to the 
Prorgbuck, the microscopic texture reveals, of a verity, that its hair 
also is very unlike that of the Antelopes, say, for instance, Cuvier’s 
Gazelle. In the accompanying woodcut (fig. 1) 4 and B delineate 
the minute textural composition of the hair of Antilocapra americana 
from two regions of the back. Though differing in absolute magni- 
tude, that from the head being the smaller, they yet agree in the 
delicate nature of the cortical substance and large-sized hexagonal
