FAMILY TROCHILIDAE 279 



Chiriqui Lagoon through Boquete began near the present small settle- 

 ment of Robalo, south of Punta Robalo, near the mouth of the river 

 of the same name. While it is improbable that the traveler came near 

 the mountain now called Cerro Robalo on the headwaters of the Rio 

 Changuinola to the west, it is evident that the bird was taken in the 

 Province of Bocas del Toro, which, therefore, is cited as the type 

 locality. 



In the specimens now at hand I can see no difference between those 

 of western Panama and Costa Rica, and those of the eastern San Bias 

 that Griscom separated under the subspecific name munda. The latter, 

 therefore, is listed as a synonym of salvini.
