Similar to E. s. hipartita in strong definition or abrupt separation 

 of the two differently colored areas on under parts of body, but 

 coloration paler throughout (the superciliary tufts usually much 

 paler, often silvery white in part), and bill relatively narrower.

c Salvador lying on the Pacific slope of Central America, it is not unlikely that 

 specimens of this species occurring there belong to the present form. I have not seen 

 Salvadorean examples, however. 



d In view of the circumstance that Lesson mentions San Carlos in Nicaragua as a 

 locality where his brother collected specimens of other species, I am inclined to 

 believe that the type of the present form also came from the same place; but as Lesson 

 stopped at various places along the Pacific coast of Central America, it may be that 

 San Carlos in Salvador is meant. The only San Carlos in Nicaragua that I am able to 

 locate on the maps is on the east side of Lake Nicaragua, near the upper part of the 

 San Juan River, but on the Pacific side of the eastern divide, though witliin the 

 Caribbean drainage area; and though no specimens have been seen from that part of Nic- 

 aragua nearer than Chontales to the northward, there can be little doubt that if the 

 species occurs there it is represented by the present form. Considering the doubt as 

 to whether the San Carlos mentioned by Lesson is really the Nicaraguan place of that 

 name, I follow Mr. Bangs in rejecting the name apiastur as the subspecific desi'j;na- 

 tion of thia form, at least until an examination of Lesson's type (should it still be in 

 existence) proves that it really l^elongs here.
