This form resembles M. amaurotis ogawce, but it may be

 feathers of the upper parts broader, especially on the crown, 

 back, and tail-feathers ; ear-coverts and lower throat darker 

 chestnut, nearly without reddish tone ; underparts generally 

 paler; wing on an average longer (127-134*5 mm. in males, 

 instead of 123-128 mm.) ; and tail and tarsus also a trifle 

 longer.

 larger, and the bill much longer, while the wing and tail 

 equal in length those of other forms of H. cantans in Japan.
