quite concealed, whereas in T. viridls the ends of -the feathers 

 only are white, the black basal portions showing conspicuously. 



Specimens referred to T. venustus, Cab., by Mr, Cassin, are 

 in Prof. Orton's collection, from Archidona, Ecuador; they 

 agree quite well with Cabanis' description, except in being of 

 the same size as T. viridis, not " somewhat smaller," and that 

 the abdomen is deep orange'; he says, "belly yellowish-orange;" 

 in describing T. viridis, he has, " belly orange," but this is 

 perliaps a variable character. 



Compared with examples of T. viridis from Bahia, Prof. 

 Orton's specimens are more of an azure instead of violet-blue, 

 the upper plumage more golden, the rump less violet, being 

 mixed with green ; the middle tail feathers are green, without 

 any shading of blue, and the abdomen and under tail coverts of 

 a deeper orange ; in the extent of white on the end of tlie tail 

 feathers, they agree with T. viridis. 



These comparative differences with T. viridis are very simi- 

 lar to those pointed out by Dr. Cabanis ; as he makes no allu- 

 sion to the ending of the outer tail feathers, I infer they are 

 the same in both. 



Specimens exactly corresponding with those from Archidona 

 are in collections received by Prof. Orton from Mr. J. Ilaux- 

 well, at Pebas on the Upper Amazon ; also, I have an example 

 from Bogota. 



The new species differs from the specimens above spoken of 

 as T. venustus, in the head and breast being of a deeper blue, 

 the rump intensely violet instead of greenish ; the middle tail 

 feathers, instead of being green, are more blue even than those 

 of T. viridis ^' the greater extent of white on the outer tail 

 feathers distinguishes it from this as well as from T. viridis ,' 

 the orange coloring below is of a deeper color than in either 

 T. venustus or T. viridis.
