With the exception of the northern portion of Tibet, we met with 

 Columba rvpestris throughout the countries traversed by us, principally 

 on the rocky mountains and in Kan-su, even up to an altitude of 12,000 feet 

 above the level of the sea. It is common on the clayey cliffs of the 

 Mongolian steppes ; and we only found there the present species, and not 

 the common Chinese C\ livia^ which does not occur in Mongolia at all. 



In spring and autumn C, ritpestris forms sometimes large flocks. 



On the Ussuri this Pigeon is common, and tolerably so on the coasts of 

 the Japanese Sea.
