In addition to having longer tails, the females of the Japanese race appear to differ from females
of the typical form in having more of the feathers of the underparts, especially those of the. breast,
squamated.
[N.B.—The difference between these two races is really very slight, and intermediate specimens
are not wanting. Such are three male birds in the British Museum from China (Gould Coll.), Amoy
(Swinhoe), and Mooleyit (.Limborg: Tweeddale Coll.), which, though referred to G. sibinca, approach
G. davisoni in the extent of slaty-grey colour on the underparts.—B-. B. S.]
