superciliaries and nuchal region ochraceous and the underparts are washed 

 with this color. It agrees more nearly with the description of the type but 

 is evidently immature.

(2445a) Automolus pallidigularis pallidigularis Lawr. 



Automolus pallidigularis Lawb., Ann. Lye. N. H. N. Y., VII, 1862, p. 465 (Lion 

 Hill, Panama); Scl. & Salv., P. Z. S., 1879, p. 522 (Remedios). 



Inhabits the Tropical Zone in Antioquia and the Magdalena Valley. 

 It has been recorded from northwestern Ecuador (Hart., Nov. Zool., 1901, 

 pp. 369, 241) as A. p. albidior, an apparently invalid form, but is unknown 

 from the Pacific coast of Colombia. 



Our specimens, particularly those from Malena and Honda, are less 

 rufous above, less ochraceous below, and have the throat whiter than the 

 type, but differ little from east Panama (Tacarcuna) specimens. 



Puerto Valdivia, 2; Malena, 2; Honda, 1. 



(2447) Automolus infuscatus infuscatus {Scl). 



Anahates infuscatus Scl., Ann. & Mag. N. H. (2), XVII, 1856, p. 468 (eastern 

 Peru). 



Three specimens from La Morelia and two from Florencia differ from 

 two specimens of A. cervicalis (Scl.) from La Union, Caura River, Venezuela 

 (= Automolus sclateri in part of authors; see Hellm., Nov. Zool. XIII, 

 1906, p. 335), having the upperparts more olivaceous. I have no Peruvian 

 specimens for comparison.

Automolus nigricauda saturatus Chapm., Bull. A. M. N. H., XXXIV, 1915, p. 644 

 (Alto Bonito, Antioquia, Col.). 



Char, subsp. — Similar to A. n. nigricauda Hart, but very much darker; the back 

 deep blackish bay instead of between raw-umber and mummy-brown, the crown 

 and nape only slightly darker than the back, with more of a claret-brown tinge, 

 which is clearer on the sides of the head; wings externally of the same color as the 

 back, tail black; breast somewhat deeper than in nigricauda the rest of the under- 

 parts darker brown, less olivaceous, the sides and particularly flanks much darker, 

 nearly the color of the back. 



Inhabits the Tropical Zone in the lower Atrato Valley and northward 

 to eastern Panama.
