Published records for Veraguas are doubtfully valid. Sclater and 

 Salvin (Exotic Ornith., pt. 1, 1866, p. 5) mention one "obtained near 

 Santiago de Veraguas in that province by Enrique Arce in 1865. . . . 

 Arce met with this same bird during his excursion to Chepo ... in 

 1864. Female taken." Salvin (Proc. Zool. Soc. London, 1867, p. 149) 

 listed the species from these same collections as "Santa Fe." Salvin 

 and Godman (Biol. Centr.-Amer., Aves, vol. 2, 1891, p. 131) give 

 the same records as from "Santa Fe (Arce)" and "Chepo (Arce)." 

 Two specimens in the British Museum (Natural History) are listed
