This species, of which I have seen many examples in the most re- 

 cently imported Bogota coUections, is very closely allied to the T. 

 velia of Cayenue ; but in the present bird the front lores and throat 

 are of the šame fuU blue as the wing-edghigs, and there is no tinge 

 of greenish colouring on the head as in its Cayenne represeutative. 

 The whole colouring is also genevally more intense, and the black 

 collar on the throat is narrovver and less defined.
