Obs. A P. cyaneocapilla, Halm, differt corpore velutino- 

 nigerrimo nee dilute brunneo-nigro, et minime cserulco la- 

 vato ; fronte nigro nee eseruleo ; pileo cseruleo intensiore sed 

 ubique magis restricto. 



Hab. Panama et Veragua. Type in mus. H. v. B. no. 

 751, Veragua {Ribbe coll.). 



The bird above deseribed was already known to some 

 writers on the birds of Panama and Veragua, but has 

 been taken to be the same as P. cyaneocapiUa, Hahn, 

 whieh name applies to the bird from Upper Amazonia. To 

 my mind it is easily distinguishable from that species (which 

 I have from Sarayacu, Eastern Ecuador, coll. Buckley) by the 

 intensity and uniformity of its black plumage, being of a 

 velvet-black, whereas in true P. cyaneocapilla the plumage is 

 brownish or greyish black, with a strong wash of blue on 

 the uropygium and abdomen. P. velutina has also a distinct 

 black frontlet; while in P. cyaneocapilla the blue of the cap 

 is produced to the bill, is also more extended laterally and 

 behind, and shows a somewhat lighter tint. 



Messrs. Sclater and Salvin, when preparing their article on 

 the birds of Panama (published in P. Z. S. 1864), had already 

 noticed the differences, saying : — " Plumage blacker, and head 

 of a rather brighter blue, than in specimens from the Peru- 

 vian Amazons; '' but they did not describe this form as a 

 different species. 



I have not yet been able to examine the bird from Bogota ; 

 but I have little doubt that it is the same as that from Upper 

 Amazonia, viz. P. cyaneocapilla, Hahn.
