As von Berlepsch has remarked ^', it is uncertain whether albiceps 

 is represented in Peru by one or more races. It is my present opinion 

 that there is more than one race, but in expectation of the receipt of 

 additional material I defer an attempt to determine the Peruvian 

 status of this species. Meanwhile, I ^-efor specimens from the Sub- 

 tropical Zone to this race, which I assume is typically represented in 

 our collections by a series from near Lima. The Temperate Zone 

 form is evidently separable.

(2949a) ELAENIA ALBICEPS, new subspedes. 



Specimens from the Temperate Zone evidently represent a zonal 

 form of this species, but I await the receipt of additional material 

 before presenting a definite conclusion in regard to their status.

(2953) ELAENIA PALLATANGAE Sclater. 



Elainea pallatxingae Sclatee, Proc. Zool. Soc, 1861, p. 407, pi. 41 (Pallatiinga, 

 Ecuador). 



Von Berlepsch refers specimens from Marcapata, southern Peru, to 

 this species. I have no topotypical material.

A single specimen, in poor condition, does not admit of satisfac- 

 tory identification.
