I have seen (and I have examined a very large number) the 
throat-mark is green, with sometimes a shading of blue, as 
might be expected. In the specimen before me the throat is 
a dark metallic purple, more like in colour the spot in L. wil - 
soni , but darker. Not wishing to add what might be a doubt¬ 
ful species to a family of birds that already possesses so many, 
and thus increase a sufficiently overburdened synonymy, I 
have never characterized this specimen, hoping to get some 
more examples similar; but thus far I have been unsuccessful. 
It was said to have been procured in Ecuador, which, if true, 
is a new locality for L. prunelli, and my specimen may belong 
to an allied species. It will be sufficient for me to call the 
attention of ornithologists to the existence of such a bird, 
and at present the bestowal of a name upon it is practically 
unnecessary.

This species was first described by Bourcier and Delattre 
in the f Bevue Zoologique 9 for 1846, from a specimen pro¬ 
cured at San Buenaventura, in Columbia. It is apparently 
more abundant in Ecuador, as most of our specimens come 
from that portion of South America. Although allied to L. 
prunelli, it is very distinct from that species, and easily recog¬ 
nizable. Formerly rare, it is now generally observed in large 
collections, and is apparently quite abundant in the districts 
it inhabits.
