size and immature age, at the Jardin du Roi in Paris, 
enabled M. Fréderic Cuvier to publish a second original 
figure, more valuable than the first as having been 
taken from the life. The same naturalist has subse- 
quently given a still more striking and characteristic 
likeness of the adult animal, taken from a drawing sent 
from India by M. Duvaucel. These figures and the 
observations which accompany them constitute the sum 
of all that has hitherto been known to science respect- 
ing this very remarkable and interesting species. 
But it seems to have escaped the observation of 
naturalists that the animal in question had been most 
accurately described as a native of Ceylon by Thunberg 
in his travels in Europe, Asia, and Africa, published 
in Swedish at Upsal in 1793, and almost immediately 
afterwards translated into German and English. It is 
true that he has confounded it with the Wanderoo, 
figured at page twenty-one of the present work; but 
this error extends no farther than the assumption of the 
name of that species, which he cites doubtfully, and 
with which his description has scarcely any features in 
common. The country name by which he designates 
it, that of Rollewai, appears more certainly to belong 
to it; for the same appellation is used by Wolf in his 
account of his residence in Ceylon, first printed at 
Berlin in 1782, and afterwards in English at London 
in 1785, and is evidently applied to the same species. 
Its coincidence with the name given by Allamand to 
the Diana appears to have misled the editor of the 
latter work ; but the descriptions both of Thunberg and 
Wolf differ so completely from that species, which is 
known to be a native of the western coast of Africa, 
that there can be no risk of their being regarded as the 
same by any scientific naturalist. The name of Rolo- 
way, as applied to the Diana, must either be a purely
