The name Phonasca humilis, proposed by Dr. Cabanis for the Costa-Rica bird of this 

 form, vras based upon a young male specimen which is said to have the characters of 

 JE. mitiuta, but to be much larger. We do not possess Costa-Rican examples of this 

 bird ; but we have a fair series from other parts of Central America, from Guatemala to 

 Panama, and others from various parts of South America, including Guiana, the home of 

 the typical JE. minuta. We notice a slight difference in size between the Guiana birds 

 and those from other places, the former having a wing averaging about one tenth of an 

 inch shorter ; but, failing other differences, we do not consider this any ground for 

 di\'iding the species. It must be remarked, however, that the bird we have described 

 as the female or young male has rather less cinereous on the throat and belly than 

 true females collected by Whitely in British Guiana ; the difference is not of much 

 importance. 



The names E. strictifrons proposed by Strickland and E. pumila by Bonaparte, in 

 the year 1851, both apply to E. minuta, as Mr. Sclater has long ago shown 2. 



The obvious diagnostic character of E. minuta is its white crissum ; this is only 

 shared in the whole genus by E. annoe, a species at once separable by its rufous head. 



In Guatemala E. minuta appears to be a rare bird, as only one other specimen has 

 reached us from there since the single male example was obtained by Salvin at Coban 

 in November 1859. In Nicaragua Belt secured only one specimen ; but from various 

 points of the State of Panama we have received skins of both sexes from our excellent 

 collector Arce.
