FAMILY 49. TEAGULID^. (2 Genera, 6 Species.) 



GENERAL DISTRIBUTION. 



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.
