quite concealed, whereas in T. viridis the ends of the feathers 

 only are white, the black basal portions showing conspicuously. 



Specimens referred to T. vemisfus, 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 

 perhaps a variable character. 



Compared with examples of T. vi?'idis from Bahia, Prof. 

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

 the u]q)er 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 the tail 

 feathers, they agree with T. viridis. 



These conq^arative differences with T. viridis are very simi- 

 lar to those pointed ont by Dr. Cabanis ; as lie makes no allu- 

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

 the same in botli. 



Specimens exactlj' corresponding with those from Archidona 

 are in collections received b}^ Prof. Orton from Mr. J. Haux- 

 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 f 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.
