rump is more bluish in its tinge, and the wings, with the exception 

 of the extremities of the outer primaries, are deeply margined with 

 pale shining blue, without the greenish hue prevalent in the New 

 Grenadian species. Below, the whole plumage is more bluish in ap- 

 pearance, particularly on the throat and breast, the feathers being 

 much more deeply terminated with the bright colouring, and not so 

 pointed in form as in Calliste niffriviridis. There is also more white 

 on the middle of the belly and vent. 



The prevalence of blue in the plumage of the Venezuelan bird, in 

 comparison with the New Grenadian, induced me to call it Calliste 

 cyanescens.
