tends southward into western Ecuador, northward to Panama and east- 

 ward at least to Venezuela. After examining Lafresnaye's type in the 

 Paris Museum, Sclater (Cat. Bds. B. M. XV, p. 152) refers 'Bogota' and 

 Antioquia specimens to the species it represents and there can therefore 

 be little doubt that the bird here under consideration is the Picolaptes al- 

 holineaius of Sclater's monograph. I can, however, detect no difference 

 between Colombia and two Panama R. R. Line specimens which have been 

 compared with the type of Picolaptes lineaticeps Lafr. and which differ from 

 it only in having the bill slightly smaller and darker. 



If, therefore, the Colombia birds are rightly referred to alholineatus it 

 follows that lineaticeps is synonymous with that species.

I provisionally refer to this form a female from La Morelia which agrees 

 with a specimen from British Guiana in having the back without shaft- 

 streaks. It is, however, paler and more rufescent in color and has the 

 shaft-streaks of crown and breast broader.

A female from Villavicencio resembles one from Cumanacoa, Venezuela, 

 but is somewhat darker and has the black margins of the crown and throat 

 more pronounced. It differs from the specimen from La Morelia, referred 

 provisionally to procurvoides, in the larger white throat area, more streaked 

 breast and dorsal shaft-streaks and darker crown. A male from Alto 

 Bonito is also to be referred to this species.
