recently collected birds from Mt. Pichincha but differ markedly from an 

 old 'Bogota' and an old Ecuador skin. The latter are almost exactly alike 

 in color. Below they are less ochraceous, more orange; above, Ie.ss olive 

 more rufous in tone. The difference as a whole is very pronounced and 

 the older skins appear to be the most richly colored. I have no Bolivian 

 specimens for comparison.

Char. sp. — ^Apparently most nearly related to Grallaria erythrotis Scl. & Salv., 

 but ear region brownish ochraceous not ochraceous-orange; breast tawny olive, not 

 ochraceous, back raw-umber, not grayish olive, etc. 



This species is known only from the Temperate Zone of the Central 

 Andes at and near Laguneta, whence came our seven specimens. Grallaria 

 erythrotis of Bolivia, presumably its nearest described relative, is known to 

 me from one Yungas, Bolivia specimen.

Secured only in the lower part of the Subtropical Zone on the western 

 slope of the Eastern Andes and at head of the Magdalena. Our specimens 

 are very uniform in color, a bird taken at La Candela on May 10, being 

 somewhat more deeply colored than the others.

We have found this to be the commonest and most widely distributed 

 bird of its genus. It inhabits mainly the Subtropical Zone but ranges as 

 low as 4500 feet and rarely reaches upward to the lower border of the 

 Temperate Zone. It frequents rather more open, scrubby and arid places 

 than the other birds of the group, and its loud, double-noted whistle, trans- 

 lated by the natives as " compra pan" is one of the most characteristic bird 

 calls. There is considerable variation in the intensity of color above, and
