114 BIRDS FROM 
One young specimen and two adult ones in winter dress. 
The old birds have no complete collar across the foreneck. 
The young bird agrees perfectly with the deseription of 
the young of O. mongolus by Stejneger in Sharpe’s Cata- 
logue; the tarso-metatarsi are however longer than the 
measurements given for mongolus and agree with those of 
pyrrhothorax syn. inconspicuus. Our specimens measure: 
bill 17—18, wing 129—132, tarso-met. 33—36 mm.
