BIRDS OF THE GALAPAGOS ARCHIPELAGO— BIDGW AY. vol.xix. 



Adams agree very closely witli tliooue from Chile described above. In- 

 some, however, there is a distinct indication of a ])aler supraloral spot. 

 The emargination of the tail is exceedingly slight, and disappears 

 altogether when the tail is half spread. The three onter rectrices have 

 the basal portion of their inner webs white, includnig the shaft, the 

 white most extensive on the onter feather, where occupying more than 

 the basal third, its posterior portion forming an acute angle with apex 

 next to the shaft.
