'Seven specimens (basal depth of bill measured in only two). 



^I have not seen specimens from Nicaragua nor from any part of northern South 

 America south of the Panama Eailroad. Judging from other species which vary 

 similarly between southern Mexico and the Isthmus of Panama, Nicaraguan speci- 

 mens are most likely referable to the southern form. Specimens from western Peru 

 and Ecuador, on the other hand, may prove on critical comparison to be separable 

 as a third form, and those from Venezuela should also be carefully compared. 



'Judging from the colored plate, Gray's bird seems to have been the southern 

 form.
