The differences between this form and the preceding, A. amabilis, 

 are so slight that they cannot be claimed to be specific. In this form 

 the bill is slightly longer, the glittering feathers of the crown extend 

 a trifle farther backward, and the blue of the throat is of a slightly 

 different shade. 



Its Costa Rican range is confined to the southwestern portion of the 

 Pacific lowlands, probably about as far north as Puntarenas. It is 

 most abundant in the lower Terraba Valley. Its habits are precisely 

 the same as those of the preceding form.

 (type and only specimen, $ , San Pedro del Mojon, Oct., 1904, Underwood). 



It is not remarkable that a form of this Nicaraguan species should 



be found in Costa Rica, but it must certainly be a very rare bird, since 



no others have been taken since. It is easily recognized by the 



chestnut-brown color of the secondaries.
