 while to the second group belong Hodgson's partridge (P. hodgsoni) from South 

 Tibet, and the smaller more northern form (P. sifanica) from Kansu, both of which 

 have only sixteen tail-feathers, and the under-parts barred with black. The common 

 partridge ranges over Europe and Western and Central Asia, as far, at least, as the 

 Barabinska Steppes and the Altai. Until recently the chestnut horse-shoe mark
