the difficulties as to their distribution vanish, and V. leucotis 

 is traced over a wide tract of country, embracing the 

 Guianas and the valleys of the upper part of the great basin 

 of the Amazons. We are thus left with three species of 

 green Vireolanius : — V. leucotis, with the range already indi- 

 cated; V. eximius, of which skins occur in trade-collections 

 sent from Bogota and which probably comes from the valleys 

 which trend into that of the Magdalena ; and V. pulchellus, 

 of Central America.

A single male specimen of this species is in Mr. Whitely's 

 collection. We are unable to discover a name for it. It 

 clearly belongs to the P. mystaceus section of the genus, in 

 which the crown of the male is either yellow or rusty red. 

 There are no strongly defined black marks about the head, 

 as in P. coronatus and its allies. 



PiPRITES CHLORION. 



Dr. Cabanis's description of this species (Arch. f. Naturg. 

 1847, i. p. 234) was based upon a specimen from Cayenne. 

 Mr. Whitely now sends us birds which must doubtless be 

 referred to this species. These differ from the species of 

 Colombia and Ecuador, which we have hitherto supposed to 

 be the same as the Guianan bird, in having the whole of the 

 under plumage except the throat grey, instead of uniform 

 yellowish olive. It is evident, therefore, that the more
