places in the western part of the State of Panama, including the Volcan de Chiriqui, 

 where Warszewiez's type was obtained. 



Gould, in his original description, states that this specimen was shot at " David in 

 the warm country of Veragua " ; but in his monograph he says at an elevation between 

 5000 and 10,000 feet above sea-level. We doubt if it is found so high, as this bird as 

 well as its near allies are all denizens of the hot low-lying forests such as cover the 

 greater part of the Isthmus of Panama. 



M'Leannan's collection contained only a single specimen of A. niveiventris which he 

 procured near Lion Hill. The prevalent species of that district is A. edwardi.

Bourcier's description of this species was based upon a bird said to have come from 

 Bogota ^, but it best suits this Costa Eican species. Not only did Gould apply the 

 name to the Costa Rica bird, but Mr. Elliot, who claimed to have the type before him, 

 did the same, so that little doubt attaches to the question. 



A. sophioB in general appearance is exceedingly like A. cyanura, but the lower back 

 is not quite so coppery, and the wings are dark to the base instead of being chestnut. 



Except for a specimen in the United States National Museum from Nicaragua, the 

 range of this species seems strictly confined to Costa Rica, where it occurs on both 

 sides of the mountain range. 



It has no near relative in the State of Panama, but in Northern Colombia and 

 in the Cauca Valley two very closely allied forms are found in A. warszewiezi and 

 A. saucerottii, which only differ in the colour of the lower back and tail.
