From an examination of the fine series of this Flycatcher 

 in the Museum at Harvard, it appears quite clear that the 

 bird described by David and Oustalet and figured in the 

 " Atlas ^^ of 'Les Oiseaux de la Chine' is an adult example 

 of this very distinct form. It is chiefly distinguished from 

 the Japanese bird by the greenish-blue, unspotted, upper 

 parts and the blue throat and breast. In the Harvard 

 examples the ■ blue breast is separated from the white 

 abdomen by a blackish marginal band. In the adult 

 Japanese bird the throat and breast are black just washed 

 with blue, and the back is smalt-blue, with more or less distinct 

 markings in the shape of black shaft-stripes, chiefly on the 

 scapulars and upper tail-coverts. I have unspotted examples 

 from Chinkiang and Shaweishan (30 miles east of the mouth 

 of the Yangtze), but all my specimens from Fohkien are 

 more or less spotted above, and are therefore referable to the 

 Japanese bird. I have no examples from north-east China, 

 where this Flycatcher is apparently very rare. Pere David, 

 who obtained specimens at Peking, makes no mention of 

 spots on the upper parts. 



The Japanese Blue and White Flycatcher apparently 

 travels up the coast through Fohkien. Chekiang and 

 S. Kiangsu to Shaweishan, where it meets the unspotted 

 green-backed form, and thence crosses to Japan.
