Tue present species was described by Mr. Gould in the list given by Messrs. Sclater and Salvin of Mr. EB.
Bartlett’s collections from the River Ucayali. It is closely allied to Z. chionogaster of Peru and Bolivia
but, according to Mr. Elliot, it differs in having the throat spotted with brown, and the tail pale green
tipped with greyish white.

The following is a copy of the original description :—

“Crown of the head, nape, shoulders, back, and upper tail-coverts green ; tail-feathers bluish green, with
green near the end; the extreme tip of all but the two central ones grey, which
gradually increases in extent as the feathers recede from the mniddle, and be

a faint zone of darker

comes most conspicuous on the
outer ones, where it pervades the whole of the outer web; wings purplish brown ; breast greyish white,
with an obscure spot of dull ereen in the centre of each feather, particularly those of the throat; flanks
dull green; lower part of the abdomen and under tail-coverts greyish white ; bill black ; feet dark brown.
Total length 32 inches, bill 4, wing 22, tail 12, tarsus 4.”
