I refer to this race two specimens from the eastern base of the Eastern 

 Andes and also two from Antioquia, though I am by no means certain that 

 they belong to the same form, nor, in the event of their being different do I 

 know to which one the name marmoratus properly belongs ! The two speci- 

 mens from east of the Andes have no chestnut-brown on the head; the two 

 Antioquia specimens have the ear-coverts and sides of the head tinged with 

 chestnut-brown and thus more nearly conform to the description of Gould's 

 type, which may have come from the western instead of the eastern side of 

 the Eastern Andes.

(134.) Odontophorus hyperythrus Gouid. 



Odontophorus hyperythrus Gould, P. Z. S., 1857, p. 223 (Bogotd); Scl. & Salv., 

 P. Z. S., 1879, p. 545 (Sta. Elena). 



Common but elusive in the Subtropical Zone of all three ranges. It 

 was far more often heard than seen.

? Odontophorus baliolus Bangs, Proc. Biol. Soc. Wash., XXIII, 1910, p. 71 

 (Naranjito, Rio Dagua, alt. 3900 ft., w. Col.). 



A Tropical Zone species which ranges from northwestern Ecuador at 

 least to the headwaters of the Atrato. Comparison of a male from Esmeral- 

 das, Ecuador, and a female from Barbacoas, both of which may be con- 

 sidered as typical, with two males respectively from the Baudo Mts. (alt. 

 2500 ft.) and Bagado (alt. 1000 ft.), to the eastward on the headwaters of 

 the Atrato, with the type of Odontophorus baliolus, kindly loaned me by 

 Mr. Bangs, strongly indicates the specific identity of baliolus with parambce. 



As with some other species of Odontophorus, the four specimens of pa-
