This epecies, peculiar to Japan soutli of Yesso, is rather strongly 

 marked and can be confounded with no other form. The male in its 

 head-markings somewhat resembles P.viridis and its allies, but the sides 

 of the head are gray and not suffused with green, as in viridis. The 

 TWO Japanese Green Woodpeckers consequently differ in a reverse way 

 from their European allies, the Japanese P. jessoensis being a green- 

 headed P. canus, while P. awol"€ra is a kind of gray-headed P. viridis. 



The female, however, is very different from the female of P. viridis.^ 

 as the upper part of the head is gray, marked with black in the middle, 

 and the upper part of the cervix only is red ; furthermore, the mous- 

 tachial stripe is red, as in the male. 



In the collection sent home by Mr. Jouy I find a young female (U. S. 

 Nat. Mus. No. 91429, Jouy, No. 703, Tate Tama, Hondo, October 19, 

 1882.) The differences from the adult female are only slight. The 

 upper part of the head is gray, with narrow blackish margins to the 

 feathers, but no medial blackish patch ; the red on the cervix and the 

 moustache is less brilliant and somewhat smaller in extent; the breast 

 is grayer and slightly suffused with reddish, and the yellow tinge of the 

 abdominal region less intensive; the black cross markings on the pos- 

 terior half of the lower surface commence higher up on the breast. 



No. 91575 ( Yolohama, April G, 1883, Jouy) is a male which differs con- 

 siderably from the two other males in the collection. The whole back 

 is gray, with a very faint wash of greenish gradually increasing towards 

 the rump; the cross markings on the under surface run farther forward, 

 and the breast shows a faint wash of reddish, like the young female de- 

 scribed above. On the whole, I am inclined to regard this specimen as 

 a bird of the foregoing year.
