ARTIODACTYLA. AE 
such it was described and sent to England; but on the subsequent 
arrival of a genuine &. Sumatrensis from Malacca it was apparent that 
. dasiotis was quite distinct. The latter is of larger size, lighter colour, 
with wide-set ears and a tufted tail. The former is smaller, darker, 
with narrow-set ears and a long tapering semi-nude tail.* The Society 
paid Mr. Jamrach £600 in 1872 for the female specimen from Malacca, 
which settled the question of separate species. A young 2. Svimatrensis 
was born in the Victoria Docks in London on December 7th, 1872, on 
board the steamship Ovchis. There is a coloured sketch of the little one 
in the‘ P. Z.S.’ for 1873, and an interesting account of it and the mother 
by Mr. Bartlett, the Superintendent of the Society’s Gardens. From 
the circumstances of the capture of the mother it appears that the 
period of gestation of the rhinoceros is about the same as that of the 
hippopotamus, viz. seven months, 
Although the number of species of living rhinoceros is but few, there 
are a great many fossil species which show that the animal was more 
plentiful and in greater variety in prehistoric times. 
Remains of the woolly rhinoceros (2. ¢vichorhinis) have been found, 
like those of the mammoth, imbedded in ice; it was about eleven and 
a-half feet in length, and its body was covered with woolly hair. A 
specimen found in 1771 or 1772 was entire, and clothed with skin, but 
so far decomposed as to prevent more than the head and feet being 
preserved ; remains of other fossil species are found throughout Europe, 
including Great Britain, and also in India. In ‘A Sketch of the History 
of the Fossil Vertebrata of India’ by Mr. R. Lydekker, published in 
the ‘ Journal of the Asiatic Society of Bengal,’ vol. xlix., 1880, will be 
found the names of eight species of fossil rhinoceros, inclusive of 
LR. Lndicus, which is found in recent alliuvia—it is found with two others 
in the Pleistocene formation, and five others are from the Pleiomiocene. 
SUB-ORDER ARTIODACTYLA. 
We now come to the second division, and a very large one, of the 
Uncu.ata, which in itself is again subdivided into non-ruminants and 
ruminants. The former comprises the pigs of the Old and the peccaries 
of the New World and the hippopotami; the latter contains the camels, 
llamas, deerlets, oxen, antelope, and deer. In the Artiodactyla the toes 
are even on all feet, being normally four (perfect and rudimentary) with 
the exception of the camel, giraffe and a few antelope, in which two 
only are present. To understand the subject thoroughly one must 
* There is a very interesting letter in Zhe Asian for July 20, 1880, p. 109, from 
Mr. J. Cockburn, about 2. Samatrensis, of which he considers &. /asiotis merely a 
variety. He says it has been shot in Cachar.—R, A. S.
