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
