Ecuador have the crown a shade darker blue, but this is not 

 quite constaut. Specimens from Chiriqui and Costa Rica 

 have large bills and rather long wings. Ten males from 

 N.W, Ecuador and one from Yuntas, S.W. Colombia, are 

 distinguished by their much smaller bills aud considerably 

 shorter wings. The tail is also a little shorter than in 

 Chiriqui skins. Four adult males from Antioquia and three 

 from Panama (McLeannari) are intermediate in size, but 

 have the small bills of the southern race. Very likely the 

 birds from south of the isthmus constitute a different form 

 worthy of a name, but I should like to see more specimens 

 from Panama before separating it. 



The following measurements shew the differences in size 



very clearly : —

1 In the Library of the Zoological Museum of Munich there is a copy 

 of Hahn's work with the original wrappers of the livraisons preserved. 

 On the wrapper of livraison xv. 1826 is printed as the date of issue, and 

 Spix's name P. coronata, published in 1825, has therefore the priority. It
