F o r our knowledge o f the existence of this species we are indebted to the researches of Mr. A . R . Wallace
and Mr Edward Bartlett, the former having obtained examples at Bahati, on the Rio Negro, and the latter
on the river Huallaga in Eastern Pern. It is most nearly allied to the Polytmus midmimus of this
Monograph (see vol. i. Introduction, pi. lxxxv., and vol. iv. p. 231, and 8vo edition of Introduction, p. 127),
but differs from that well-known bird in its under tail-eoverts being pure white. ^ ^
The specific appellation assigned to it first appeared in Messrs. Sclater and Salvin’s I List of the Birds
collected by Mr. Wallace on the Lower Amazon and Rio Negro,” and subsequently in the same gentlemens
1 Catalogue of Birds collected by Mr. E. Bartlett on the river Huallaga, Eastern Peru.” B H j
Mule. Entire npper and under surface pale flowery green, with the exception of the head, which is brown
and the crissum, which is white; wing-coverts golden green ; wing purplish brown ; tail bright green ; bd
light fleshy brown. Total length 3 f inches, bill I, wiug 2 i, tail i , tarsus A.
Female. Much smaller than the male, but similarly coloured, except that the three outer tail-feathers on
each side are tipped with white, like those of the female o f Polytmus mridissimus. [ B B S ]
