Jeusxis Wood-Nymph was discovered by the well-known Polish traveller after whom the species Is
named, at Soriano in Peru. Mr. Elliot writes concerning the present bird:—‘*This is a diminutive
of 7. nigrofasciata; and there is absolutely no difference between the two except in size. The rectrices
of 7. yelski are narrow, but not more so than accords with its dimensions. I compared the type
with specimens of 7. negrofasciata, and could distinguish no difference, save that 7. jelskii was a little
smaller.”

The Plate represents the adult male in three positions, and is drawn from a specimen lent to us by
Dr. Taczanowski.
