Formicivora quixensis consobrina Hellm., P. Z. S., 1911, p. 1163 (Bahia del Choco; 

 N6vita; Sipi). 



Inhabits the Tropical Zone of the Pacific Coast and Antioquia. Co- 

 lombia specimens agree with those from Ecuador and differ from those 

 from Panama and northward in the broader white tips to the rectrices and 

 deeper color of the female.

(2021) Drymophila caudata caudata (Scl).

Drymophila caudata striaticeps Chapm., Bull. A. M. N. H., XXXI, 1912, p. 145 

 (Salento, Cen. Andes, Col.). 



Found by us in the Subtropical Zone of the Western and Central Andes. 

 We did not secure it in the Bogota region. In the absence of topotypical 

 specimens I was led to believe, both by Sclater's original description and 

 plate {I. c), as well as by his description in the British Museum Catalogue 

 (XV, p. 253), in which it is said the "centre of the cap is black," that true 

 caudata had the cap black and, consequently, that Santa Marta males, 

 in which the cap is black represented this form. Hence the birds from 

 western Colombia with a striped crown were described under the name 

 striaticeps (I. c). 



HellmajT, however, writes me that the type, as well as other Bogota 

 specimens which he has examined, have the crown striped, and are not 

 separable from Ecuadorian specimens. It follows, therefore, that striati- 

 ceps becomes a synonym of caudata, from which the black-crowned Santa 

 Marta bird is separable.^

1 Since the above was written the Santa Marta race has been described as Drymophila caudata
