PICA PICA SERICEA Gould. 



Thirteen specimens young and adults of both sexes, Ichang, and Changy- 

 anghsien, Hupeh, and Kiating, Luluping, and Washan, western Szechwan, all 

 seasons. 



PICA PICA BOTTANENSIS Delessert. 



Two specimens, youngish male and female, Shuowlow near the Ramala 

 Pass, western Szechwan, at 12,500 feet altitude, August 22, 1908. 



These birds were full grown and had wings and tail as in the adult; in the 

 female most of the feathers of the back are of adult plumage; and in both, the

 and Luluping, Szechwan, all seasons.

 occasionally in various places.
