Two specimens from base of Serra da Lua, near Boa Vista, Rio Branco region, 

 I have referred provisonally to this form, but they differ sufficiently to suggest that 

 a larger series may prove them not to be the same. They agree with undulatus in 

 the brownish olive ground color of the upper parts. 



b Picumnus salvini HARGITT: Similar to P. undulatus of Guiana, but distinguished 

 by the feathers of the belly being black, spotted in the middle, and girded (or sur- 

 rounded) with a fuscous margin and also in having the feathers of the throat tipped 

 with black but without the median black spot. This bird is unknown to me. 



PENARD and PENARD (De Vog. van Guyana, I. e.) give Sclater credit for the 

 name, but I am unable to find Sclater's original description. The explanation 

 suggested by Bangs and Penard (/. c.) seems probable.
