 robust and not so compressed near the tip.

Remarks. E. browni and E. sororia are closely related, though entirely 

 distinct species. From the material Mr. Brown has so far collected, I 

 should judge that E. sororia is found at rather lower elevations than E. 

 browni, though their ranges meet. At Palomina Mr. Brown found only 

 E. sororia. At San Miguel he took five examples of E. browni and one of 

 E. sororia. The molting season of the two species appears to be differ 

 ent, as the specimens of E. browni shot at different dates in June at San 

 Miguel are all in fresh plumage, while all the examples of E. sororia taken 

 at Palomina in May and the one killed at San Miguel, June 16, are in 

 somewhat worn plumage. The great difference in color between the two 

 series may be in part seasonal ; but E. sororia is probably never very 

 greenish on the upper surface. 



Both El&nia browni and E. sororia seem to belong in that section of 

 the genus called Myiopagis by Salvin and Godnian : * a group I should be 

 unwilling to allow even subgeneric rank.
