134. Thectocercus hagmorrhous neoxenus (Cory). 

 One specimen : Rio Hacha. 



This is a species of the Arid Tropical Zone of Venezuela, which 

 finds its western limit in the Goajira region. The single specimen 

 agrees well with a small series from western Venezuela, which we 

 refer provisionally to the form described a few years ago by Mr. Cory 

 from Margarita Island. The junior author found it fairly common at 

 Rio Hacha and Arroya de Arenas in July, 1920. 



135. Ara militaris (Linnaeus). 



Ara militaris Bangs, Proc. Biol. Soc. Washington, XII, 189S, 132 (" Santa 

 Marta "). — Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 133 (Bonda; Sal- 

 vin and Godman's and Bangs' references). 



Four specimens: Bonda and Las Nubes. 



Mexican specimens average a little larger, it is true, but we cannot 

 see our way clear to recognizing them as subspecifically distinct on that 

 ground alone. 



This is the most common species of macaw in the vicinity of Santa 

 Marta itself, ranging from sea-level up to the lower edge of the Sub- 

 tropical Zone, to 5,000 feet at least. 



136. Ara chloroptera Gray. 



Ara chloroptera Salvin and Godman, Ibis, 1880, 176 (Valle de Upar). — Sal- 

 vadori, Cat. Birds Brit. Mus., XX, 1891, 156 (Valle de Upar). — Bangs, 

 Proc. Biol. Soc. Washington, XII, 1898, 132 (" Santa Marta "). — Allen, 

 Bull. Am. Mus. Nat. Hist., XIII. 1900, 133 (Salvin and Godman's and Bangs' 

 references). — Ridgway, Bull. U. S. Nat. Mus., No. 50, VII, 1916, 125 

 (" Santa Marta," Dibulla, Fundacion, and Valle de Upar, in range ; meas. ; 

 references). 



Five specimens : Fundacion and Dibulla. 



This is the common species of macaw in the lowlands and lower foot- 

 hills of the region between Santa Marta and Rio Hacha, and is also 

 found, although less commonly, in the forested country about Funda- 

 cion. Simons secured it on the. south side of the Sierra Nevada, at 

 Valle de Upar, while the writer has observed it at Valencia, in the 



same general region, as well as at Arroya de Arenas, farther nortb.
