Remarks. — This race is apparently confined to Peru and Bolivia, since 

 birds of this species from Brazil, Colombia, and probably eastern Ecuador, 

 belong to other forms. The absence of racquets on the middle rectrices is 

 evidently only a subspecific character, as this occurs sometimes in other 

 races which normally have well-defined racquets. 



The Bolivian bird has been described as a new race. Electron platy- 

 rhinicliKni iucdianiim:, Avhich is similar to FAcctron platyrlnjnchum pyrrho- 

 hicinuiii. l)ut is supposed to have the chin spot more bluish, the posterior 

 under parts and exposed surfaces of .i'emiges somewhat less bluish, and the 

 rufescent areas of chest slightly darker and didler. These differences are 

 apparently individual, an opinion in which Mr. Todd himself now concurs.
