ef the characters which have been proposed for this Woodpecker are shown 
by the large series before me to be subject to much variation, but this, as in 
the case of Melanerpes angustzfrons, is confined within limits which do not over- 
lap, if, indeed, they quite reach those of the bird’s nearest allies. The restric- 
tion of the black on the outer tail feathers is perhaps its best distinguishing 
feature, although this is not at all uniform, for many of my specimens have 
three complete dark bars crossing both webs of the outer tail feathers, while in 
one a fourth bar is only broken by a small space near the middle of the feather. 
The width of the dark bars on the back is also variable, although these bars 
are usually wider than in any of the allied forms. The feet average larger 
than those of bairdi, but they are by no means always larger. <A difference 
which I do not find mentioned in descriptions, but which is shown by my 
series to be quite as constant as most of the characters that have been pro- 
posed, is that the white spots on the top of the head are much larger and more 
numerous than in bairdi, while the red is less vivid and more nearly restricted 
to the crown and occiput. In one specimen (No. 17,231, La Paz, March 26,
