The Tragulidse are a group of small, hornless; deer-like animals,
with tusks in the upper jaw, and having some structural affinities
with the camels. The musk-deer was formerly classed in this
family, which it resembles externally ; but a minute examination
of its structure by M. Milne-Edwards, has shown it to be more
nearly allied to the true deer. The Chevrotains, or mouse-deer,
Tragulus (5 species), range over all India to the foot of the
Himalayas and Ceylon, and through Assam, Malacca, and Cam-
bodja, to Sumatra, Borneo, and Java (Plate VIII., vol. i. p.
337). Hymnosclius (1 species), is found in West Africa.
Extinct Tragulidce.—A species of HyomoscJms is said to have
been found in the Miocene of the South of France, as weU as
three extinct genera, Dremotherium (also found in Greece), with
Lophiomeryx from the Upper Miocene, said to be alKed to Tra-
gulus ; and Ampliitragulus from the Lower Miocene, of more
remote affinities, and sometimes placed among the Deer. There
seems to be no doubt, however, that this family existed in Europe
in Miocene times ;
tribution is satisfactorily accounted for.
