China — Chefoo (Swiuhoe 2), Central China — Kiaugsi (David b 4), South China 
(StyanW, Do La Touche 24); Philippines — Luzon (Othberg .9, 7, Mait.-Heriot 75),

This Pipit was first obtained by Mr. Wallace in Batchian, but was not 
immediately described as new by G. R. Gray, and it was rediscovered rather 
more than thirty years ago by Sw inhoe on the island of Amoy during the 
bird’s transit from its winter quarters to its breeding grounds in May. Since then, 
thanks to the observations of Swinhoe, Seebohm, Dybowski, Stejneger and 
others, a fairly good knowledge of its distribution, habits and migration has 
been obtained. Five nests were found by Messrs. Seebohm and Harvie- 
Brown on the Petchora, at the end of June and beginning of July, 1875; then 
it was again found breeding by Seebohm in the valley of the Yenesei in July, 
by Dr. Dybowski in Kamtschatka, and by Dr. Stejneger in the Commander 
Islands. In the last locality it is one of the commonest birds; the first eggs 
were obtained on the 30**“ May, and eggs of the second sitting in July. In North 
China Swinhoe ( 2 ) observed that numbers pass on migration near Chefoo, but 
in South China Messrs. Styan and De La Touche have very rarely met with
