Mr. D. G. Elliot on the Trochilidse. 59 



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. pruiielli, 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 bii'd, 

 and at present the bestowal of a name upon it is practically 

 unnecessary.

Hab. Ecuador; San Buenaventura, Columbia [Bourcier). 



This species was first described by Bourcier and Delattre 

 in the ' Revue Zoologique ' 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.
