these bright birds ; but I have not beeu able to arrange the series 

 before me so as to show that the differences arc in any way localized. 

 Compared with 0. splendidas of the Argentine llepublic, Bourcier's 

 specimen of G. aureiventris, from Bolivia, has a shorter bill and 

 more golden tint on the abdomen ; the crown, too, is more golden. 

 -I am not siire that these colour-differences are normal, but rather 

 due to stain of some kind. C. pliaeton belongs to the long-billed 

 form. 



The Mendoza specimens are intermediate between the two extremes 

 as regards the length of their bills, and vary considerably amongst 

 themselves both in the colour of the abdomen and in that of the 

 crown. 



A larger series of specimens with authentic localities and dates 

 of capture are necessary to determine satisfactorily the status of these 

 forms. 



Count V. Berlepsch tells me that C. egregius, Heine, from Eio 

 Grande do Sul, is intermediate between C. splcndidiis and C. puch- 

 erani, and may be called with equal propriety a " subsi)ecies " of 

 either.
