Santa Ana (J. Zeledon). 



In my Catalogue of Birds from Panama (Ann. X. Y. I. . . I'. 

 VII., p. 479), I referred this species erroneously to .1. rvficoUU, 

 Gm. ; it is, however, A. ruficollis of Swainson. For some time 

 I have known that the Panama bird was not ruficoUis ) Gm.; i' 

 differed, in its much deeper color below, from specimens of .1. 

 cayennensui in the Phil. Acad., but in them the color has no doubt 

 faded. The Costa Pica example before me, as well as others 

 from Nicaragua, are identical with those from Panama, and com- 

 paring them with specimens from the Upper Amazon and 

 Bogota (which I take to be cayennensis), I can see no essential 

 points of difference. 



This species seems to be widely distributed, but in Honduras 

 and Guatemala it is replaced by my A. albivenlri*.
