 [W. W. Brown]; type in Bangs coll.); Auk, XXIV, 1907, 299 (Boruca, El 

 Pozo, and Lagarto de Terraba [Underwood]).

Azul de Pirris (Underwood).

(Carriker); Pozo Azul de Pirris (Underwood). Fourteen skins. 



Upon comparison of skins of A. pallidigularis from Costa Rica and 

 Chiriqui with specimens from Loma del Leon, Panama (type locality of 

 A. pallidigularis Lawrence), I find that the differences between the 

 two forms are too small to admit of specific distinction for the northern 

 form, and I have therefore made Mr. Bangs' A. exsertus a subspecies 

 of A. pallidigularis Lawrence, to which it is most nearly allied. 



In Mr. Bangs' paper on the birds of the Terraba Valley (Auk, XXIV, 

 1907, 299), appears a printer's error which should be corrected. 

 Under A. virgatus he says : " This is of course the bird recorded by 

 Cherrie as A. pallidigularis. 1,1 This remark should have been placed 

 by the compositor under the following species, A. exsertus, to which 

 it very obviously refers. 



In Costa Rica this bird is confined to the southwestern Pacific low- 

 lands, from the Rio Grande de Tarcoles southward. It is abundant 

 at Pozo Azul de Pirris and in the Terraba Valley. Its habits are 

 the same as those of A. cervinigularis hypophceus. 



376. Philydor panerythrus rufescens (Lawrence). 



Philydor rufescens Lawrence, Ann. Lye. N. Y., VIII, 1866, 345 (Birris, Costa
