Sclater records (Cat. B. M. XV, p. 101) both ruficaudatus and suhfuhus 

 from Gualaquiza, essentially the locality in which our Zaruma specimens 

 were taken. I do not, therefore, feel that I am in a position to separate 

 the Colombian bird without having seen authentic specimens of both rufi- 

 caudabus and svhfuhus.

(2473) Philydor montanus striaticoUis {Scl.). 

 Anabates striaticoUis Scl., P. Z. S., 1857, p. 17 ('Bogotd' — I suggest Fusugasugd). 



Inhabits the Subtropical Zone of all three ranges. Specimens from the 

 mountains about the Cauca Valley average deeper in color below; and 

 thus more nearly resemble P. m. anxius (Bangs) of Santa Marta than do 

 those of the Bogota region. The Santa Marta form, however, is less rufous 

 above and has the throat fulvous. The Peruvian form, P. m. montanus, 

 is decidedly more rufous above than striaticoUis and has the crown rufous 

 but little darker than the back, instead of olivaceous, distinctly unlike the 

 back.

(2477) Thripadectes flammulatus {Eyton). 



Anabates flammulatus Etton, Cont. Orn., 1849, p. 131 (BogotA). 

 Thripadectes flammulatus Scl. & Salv., P. Z. S., 1879, p. 521 (Frontino); Allen, 

 BuU. A. M. N. H., XIII, 1900, p. 158 (EI Libano). 



We have met with this species only in the Temperate Zone of the Central 

 Andes.

(2480) Thripadectes virgaticeps sclateri Berl. 



Thripadectes sclateri Bbrl., Proo. IV Int. Cong., 1905, p. 365, 1907 (St. Pablo, 

 w. Colombia, 4500 ft.); Hellm., P. Z. S., 1911, p. 1149 (Crit.). 



Rhopoctites alogus Bangs, Proo. Biol. Soc. Wash., XXIII, 1910, p. 72 (Pavas, 

 w. Colombia, 440 ft.). Type examined. 



Inhabits the Subtropical Zone of the Western Andes. Hellmayr's 

 (Z. c.) statement that Rhopoctites alogus Bangs is identical with this species, 

 is confirmed by the examination of Bangs' type. Comparison with the type 

 of Thripadectes virgaticeps Lawr., further indicates that sclateri is a sub- 

 species of that form. The diiferences between the two consist only of size
