While these Punjab beds are distinguished from the Miocene fauna of the Lower Manchhar by the rarity of anthracotheres and the absence of Hyotherium, they appear to contain a somewhat older fauna than the true Siwaliks of the sub-Hima- layas. Thus, of the surviving Miocene forms several are recorded in the Punjab only, namely: Dinotherium, Machcerodus, Dorcatherium, anthraco- theres. More primitive mastodons are also chiefly from the Punjal). The Siwalik Group, or Siwaliks proper, are exposed in the sub-Himalayas, a long range of hills which for a distance of 1,500 miles advance along.
