parently to be referred to this Amazonian species. It is much more deeply 

 colored above than a specimen of punctipectus in similar plumage from Ma- 

 ripa on the lower Orinoco, and is nearer in color and pattern to an immature 

 female from the headwaters of the Huallaga River, Peru. Two adults from 

 Moyobamba, Peru, loaned me by the Field Museum, are somewhat darker 

 above than one from Santarem, Brazil, indicating that true punctigula 

 ranges the length of the Amazon. Indeed I can find but little difference 

 in color between these specimens and two adults from Paramaribo which 

 may be assumed typically to represent true punctigula. The latter are, 

 however, slightly smaller and have a shorter bill.

Specimens from the vicinity of Villavicencio appear typically to repre- 

 sent this form. They agree on the whole with an adult from Cumana, 

 loaned me by the Field Museum, and since Hellmayr (Abhd. Wiss., 1906, 

 p. 607) refers to this form specimens from Caicara and Altagracia on the 

 middle Orinoco, it evidently occupies the larger part of Venezuela. Com- 

 pared with true punctigula of which, thanks to Mr. Penard, I have three 

 specimens from the vicinity of Paramaribo, punctipectus differs mainly in 

 having the back warbler-green instead of antique-brown, and in being larger 

 (wing 119 mm. as compared with 112 mm.).

This form of the arid, Caribbean, coastal region, is one of the most dis- 

 tinct of the group. In its white, black-streaked throat it agrees with stria- 

 tigularis, but it differs markedly from that race in its paler, less spotted 

 underparts and in the much narrower, almost obsolete bars of the back. 

 We have one Santa Marta specimen.
