(1031) Phcethornis griseogularis Gould. 



Phaethomis griseogularis Gould, P. Z. S., 1851, p. 115 (Colombia). 



An immature specimen from Florencia is apparently to be referred to 

 this species. 



(1032) Phcethornis striigularis striigularis Gould. 



Phaethomis striigularis GotrLD, Mon. Trochil., I, 1854, facing pi. 37 (Bogotd). 

 Pygmomis striigularis Allen, Bull. A. M. N. H., XIII, 1900, p. 138 (La Concep- 

 cion). 



Inhabits the Bogota region and apparently reaches westward into 

 Antioquia, a specimen from Puerto Valdivia in the lower Cauca River being 

 referable to this form rather than to that occupying the Pacific coast, and 

 described below.

(1032 a) Phcethornis striigularis subrufescens subsp. nov. 



PhcBthornis striigularis Simon & Dalmas (nee Gould), Ornis, XI, 1901, p. 218 

 (Naranjo). 



Char, subsp. — Similar to P. s. striigularis Gould but smaller, with a 

 shorter bill, underparts more rufescent, the throat more uniform, and less 

 streaked. 



Type. — No. 117654, Am. Mus. Nat. Hist., Barbacoas, Narifio, Colombia; 

 August 30, 1912; W. B. Richardson. 



Range. — The humid Tropical Zone of the Pacific coast region of Colom- 

 bia and Ecuador. 



Oberholser (Proc. U. S. N. M., XXIV, 1902, p. 313) has.called attention 

 to the distinguishing characters of the form of this species inhabiting western 

 Ecuador, and has applied to it the name atrimentalis Lawr., a species which 

 has commonly been synonymized with striigularis. Examination of the 

 type, however, (Am. Mus. Nat. Hist., 46225) shows that it belongs in the 

 group having the underparts cinnamon-rufous, the throat black. In the 

 coloration of these parts, and in its black auriculars, the type of atrimentalis 

 resembles longuemareus; the upperparts are greener than in striigularis 

 and the central tail-feathers are broader and more sharply pointed; the 

 lower mandible is bicolor not concolor as in longuemareus. A specimen from 

 Bogota agrees with the type of atrimentalis but has the back more coppery.
