All the character-s 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 anrjustifrons, 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 liave 

 three complete dark bars crossing both webs of the outer tail feathers, wliile 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 hairdi, 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 hairdi, 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,
