226 MR. R.SWINHOE ON THE MAMMALS OF HAINAN. [Apr. 28, 
be Presbytes maurus (Schreber). There is a specimen of this in the 
British Museum, brought from Canton by Mr. J. Reeves. 
2. THe Reppisu-Grey Monkey. Macacus erythreus (Schre- 
ber). 
Du Halde (op. cit.) says that in Hainan “ there are Grey Monkeys, 
which are very ugly and very common.” The Chinese Gazetteer 
has the following :—‘‘ How (or Monkey). The She-show (Notes 
on Animals) states that the Monkey has no stomach, but digests its 
food by jumping about. According to ancient authors, Kiungchow 
abounds in Monkeys, and its people make a trade by selling young 
ones.” 
About the jungles of Nychow (S. Hainan) Monkeys were very 
common. On our landing, abreast of the ship we saw a large party 
of them on the beach, which at once retired into a grove above high- 
water mark. We watched them running along the boughs of the 
trees and jumping from branch to branch. The discharge of a 
fowling-piece soon made them scurry away into the thicket; but 
every now and again their heads would appear from the higher bushes 
watching the movements of the enemy. At last, when they observed 
that our presence implied actual danger to themselves, they climbed 
the hills and posted themselves about conspicuous rocks, where they 
chattered and grunted out of danger. Their cries were very like 
those of Macacus cyclopis, mihi, of Formosa. In the neighbourhood 
of Nychow city we found a large number of them in a thick wood 
that surrounded the hovel of a Le native, and one of our party suc- 
ceeded in knocking over a fine female with a cartridge. Its irides 
were yellowish brown tinged with green. Eyes somewhat oval. 
Face long, narrow, with a somewhat projecting mouth; the skin 
tinged with reddish yellow, and sprinkled with short silky buff- 
coloured hair, longer and coarser on the lips, chin, and cheeks. A 
few long black hairs were scattered on the centre of the forehead and 
on the space beneath the eyes. -The ear was well developed, and thinly 
clothed with hair. 
Skull, 9 .—The mouth projects | inch in front of the line of the 
orbital ridge. Height of the skull, from top of frontal bone to angle 
of the lower jaw, 2°6 inches; from orbital ridge to the same 2°43; 
length of lower jaw 2°15; hind corner of malar arch to front of in- 
cisors 2'45; from ditto to occipital crest 1:5; greatest diameter of 
rounded orbit *9 ; breadth of skull, from one malar arch to the other, 
2:6; across base of brain-case 2°25. Nasal aperture shaped like a 
subverted cone; vertical length ‘65, greatest breadth -42. Central 
pair of incisors of upper jaw about one-third larger than those of 
lower. Only fourteen teeth in each jaw; the four hind molars not 
yet acquired. The frontal bone slopes rapidly backwards from the 
orbital ridge, rising only a little in its centre, and thus leaves a very 
inclined forehead. 
Vertical length of ear 1:3, breadth -9; bare palm 1°85 long, 
1:1 broad; middle finger 1°2 long ; length of sole 3-2, breadth 1°5.; 
Length of body 15 inches; of entire arm to tips of fingers about
