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). Hyomoschus (1 species), is found in West Africa. 
Extinct Tragulidce. — A species of Hyomoschus is said to have 
been found in the Miocene of the South of France, as well as 
three extinct genera, Dremotherium (also found in Greece), with 
Lophiomeryx from the Upper Miocene, said to be allied to Tra- 
gulus ; and Amphitragulus 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 ; and thus another case of discontinuous dis- 
tribution is satisfactorily accounted for.
