PAPIO CTNOCEPHALUS.

lumbar region, and tail. On the lower half of the radial portion of the fore limb 
and on the dorsum of the hand the black tips of the hairs show here and there ; 
Avhereas on the front of the hind limb and on the dorsum of the foot the black tips 
are hardly, if at all, developed, but, as in P. ihoth and those already described, the tips 
of the toes are covered with long grey hairs. The hair on the shoulders is long, but 
the annuli are feebly indicated, with the exception of the subapical bands. The long 
hairs on the shoulders measure over 200 mm. in length, while those on the lumbar 
region are not more than 85 mm. long. On the outsides of the hind legs some of the 
longer hairs are 110 mm. in length. Four or five of the coloured rings of the hairs can 
be more or less detected, but fewer are present in the shorter hairs. The sides of the 
muzzle, before the eyes, are clad with short whitish hairs, as in the foregoing baboons, 
and the lips are also haired the same as in them. The skull of this specimen proves 
it to have been not full-grown, and consequently the form of the animal is more 
slender than that of adults. 
The baboon in the Paris Museum so frequently described by French authors under 
the name of Cynoce'ph.alus habuin, has unfortunately had the face painted black and 
has been stuffed in a sitting position. 
This specimen is of a rich, almost golden yellow, but with an intermixture of black, 
as the hairs usually terminate in black tips. Longer hairs are intermixed, and as they 
are generally of a paler colour than the shorter hairs, they are very distinct. The 
hairs on the head, more especially on the vertex, are long, as in P. fhoth, and their 
black tips are particularly well developed. The usual, somewhat dense, line of short 
hairs is present on the side of the face. The whiskers are whitish with a few black tips, 
the hairs on the under surface of the throat, behind the chin, and on the inner sides of 
the limbs are pale yellowish white. The limbs are coloured like the body, and this 
colour on the hands is prolonged to the middle of the metacarpals, the hairs on the 
rest of the hand and fingers being greyish yellow or yellowish white like the inner- 
sides of the limbs. Much the same colour prevails on the feet, with long greyish- 
yellow hairs over the toes. ■ — ' 
As already stated, Mr. Matschie ^ regarded what he designated C. cynocephalus, 
Linn., and C. lahuin, Is. Geoffr. St.-Hil., as two distinct species, which differed 
from one another in the following manner:—the former was greenish yellow, in 
certain lights yellow-brown, tinged only on the head with a little black; whereas the 
latter was intensely green, with a strong sprinkle of black on the head and on the back 
of the neck, with a few intermixed yellow-green hairs. These distinctions, however, 
are too ill-defined to be of value when the considerable series of the baboons herein 
mentioned are dealt with. The skull-characters, moreover, referred to by Matschie 
seem to be more indicative of diversity of age than of anything else.
