see more material before committing myself definitely on this subject, but 

 I feel that when the range and relationships in Colombia of the forms 

 of this group are satisfactorily determined, we shall have one race in the 

 humid lower Cauca-Magdalena Fauna of the Tropical Zone, one in the East 

 Andean Subtropical Fauna, and a third in the West Andean Subtropical 

 Fauna which ranges downward to the upperpart of the Tropical Zone.

(1943) Dysithamnus puncticeps flemmingi Hart. 



Dysithamnus flemmingi Hakt., BuU. B. O. C, XI, 1900, p. 38 (Rio Verde, Ecua- 

 dor). 



Three males and three females from Barbacoas are to be referred to 

 this form which is obviously a representative of D. p. puncticeps. Of two 

 males from central western Colombia, as stated below, one is nearer to 

 puncticeps the other to flemmingi.

' (1943as) Dysithamnus puncticeps puncticeps Salv. 



Dysithamnus puncticeps Salv., P. Z. S., 1866, p. 72 (Veragua). 



Ten specimens from the Atrato and upper San Juan are intermediate 

 between puncticeps and flemmingi. Some are nearer one, some the other, 

 but as a whole, the series is referable to the Panama race.

(1944) Dysithamnus leucostictus Scl. 



Dysithamnus leucostictus Scl., P. Z. S., 1858, p. 66, pi. cxl, 9 ad. (R. Napo, Ec.) ; 

 Tacz. & Berl., Ibid. 1885, p. 99, c?. 



Two females from Buena Vista agree essentially with Sclater's plate 

 and description. Although these birds were taken in the heart of the east 

 Bogota region, this species does not appear to have been before recorded 

 from Colombia.

Found by us only in Amazonian Colombia. I have no material for 

 comparison. As before stated, I have followed Brabourne and Chubb, in
