barred above, and in one the head is more nearly concolor with the back. 

 In'the other, however, the crown is pronouncedly more rufescent than the 

 back. A similar variation is shown in a small series from El Real, eastern 

 Panama, one of which has the crown brightly rufescent, while in another 

 it is nearly like the back. Both are males. I have seen no authentic speci- 

 mens of D. s. hesperius Bangs.

A male from Florencia is apparently to be referred to this species which 

 appears not to have been before recorded from Colombia. 



Compared with D. s. sancti-thomw, the difPerences exhibited by this 

 specimen are obviously of only subspecific ^-alue.

Inhabits the Paramo Zone of all three ranges. A male from Santa 

 Isabel, apparently in 'first winter' plumage, has only an incomplete ter- 

 minal tail-band. In other respects our specimens agree essentiallj' with 

 others from Ecuador.

Restricted to the Temperate Zone where it is of evidently local occur- 

 rence in all three ranges. It was not common at Laguneta in the Central 

 Andes, and we did not encounter it at all in the Bogota region where, how- 

 ever, we secured three skins with data from a local collector, taken at Choa- 

 chi, about twenty miles northeast of Bogota and north of Chipaque. 



Old 'BogotI,' and old 'Quito' skins show a much redder tone than fresh 

 ones from these localities, the former being mummy-brown, the latter sepia 

 above.
