Tapj.k IX. — Di.striljtitioH of tin- Caiiid-s 



The traguliiies. recent and extinct, are a heterogeneous assemhlagc of 

 primitive ruminants, whose real affinities have been much disputed. In 

 the present writer's opinion, the living East Indian chevrotains should 

 be associated with Ilypertragulus of the North American Oligocene and 

 perhaps Microtragulus of the South American Pliocene, and tlie center 

 of distribution of this group hypothetically placed along the northeastern 

 coast region of Asia (r/. tapirs). The living water-chevrotain {Hya'~ 

 moschus) and most of the so-called tragulines of the European Oligocene 

 and Upper Eocene are to be regarded as primitive stages of true Pecora. 

 Lepiomeryx, Protoceras and Ilelerornery.r are related forms from the 

 Xorth American Oligocene. Among these primitive forms, some {Lep- 

 iomeryx) display affinities to the deer, others (Proloceras, Jfeteromeryx) 

 to giraffes and antelopes. 



^ C. siraJensis of tlie Siwalik beds is doulitfully consenoric with the modern species 

 and, along with the so-callod I'rocamehu^ described by Mme. I'avlow from the IMeistocene 

 of Russia, appears to be an intermediate stage between Proi aiiiehos and Cumrliis.
