Specimens from Prince of Wales Island have been referred to 

 D. V. picoideus, mainly because of the restricted and broken 

 white dorsal area, but the hairy woodpeckers from this and 

 adjacent islands have not the barred rectrices, nor, as a rule, 

 any markings on the lateral under parts, and should not be 

 classed with that form. 



There are at hand fourteen examples of the Sitkan hairy 

 woodpecker, from the following localities: Admiralty Island, 

 four; Chic'hagof Island, one; Baranof Island, one; Prince of 

 Wales Island, one; Etolin Island, two; Coronation Island, one; 

 Dall Island, one ; Wrangel Island, one ; Boca de Quadra, two. 



There are six adult males. Two of these, one from Dall and 

 one from Admiralty Island, both taken at the end of May, are 

 closely similar, with the ventral coloration strongly suffused with 

 huffy, the dorsal stripe narrow and broken with black markings, 

 and the flanks distinctly barred; while two others (one from 

 Sitka, the other from Etolin Island, both shot in July), have the 

 dorsal stripe broader, more purely white and less checkered, the 

 lower parts with less of the buffy suffusion, and the flanks un- 

 marked. The remaining two males, one from Chichagof, and the 

 other from Admiralty, are alwut intermediate between the 

 extremes shown by the others. 



Of the six adult females at hand, all have the head markings 

 and dorsal stripe pure white, the latter more or less broken by 

 black streaks and bars, but in every case the nasal tufts are of 

 the distinctive brownish yellow color. 



Two Juvenal males in the series, one from Admiralty, the 

 other from Etolin Island, have the dorsal stripe distinctly barred. 



The most obvious difference between sitkensis and harrisi is 

 the much paler color of the lower parts in the former. The 

 Sitkan woodpeckers differ somewhat among themselves in this 

 regard, but even those in which the smoky suffusion is most 

 intense, and the coloration darkest, are of a distinctly different 

 hue from harrisi. In sitkensis the lower parts are of a pinkish, 

 or buffy cast, while in harrin they are slaty or smoky gray. 



Some specimens of liarrisi shot in May and June, in worn and 

 faded plumage, approach in the color of the ventral surface
