* Charadrius dubius jerdoni (Legge) . 



1 adult 9 , Mengtsze, 5 ]March. This specimen has a wing only 101.5 

 mm. long and therefore would seem to belong to the small race that 

 breeds in the Himalayas.

 4 specimens, Mengtsze, 10 Sept., 1910.

The eastern race of the Green-shanks has been formally recognized 

 by Matthews under the above name. If it can be maintained at all, 

 it certainly is only a very close subspecies. We can find no differences 

 in measurements between eastern and western specimens and no color
