The present species was described by Mr. Gould in the list given by Messrs. Sclater and Salvin of Mr. E.
Bartlett’s collections from the River Ucayali. It is closely allied to L . 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 o f the original description—
“ Crown o f the head, nape, shoulders, back, and upper tail-coverts green ; tail-feathers bluish greeu, with
a faint zone of darker green near the end; the extreme tip o f all but the two ceutral ones grey, which
gradually increases in extent as the feathers recede from the middle, and becomes most conspicuous on the
outer ones, where it pervades the whole o f the outer web; wings purplish brown; breast greyish white,
with an obscure spot of dull green in the centre o f each feather, particularly those of the throat; flanks
dull green; lower part o f the abdomen and uuder tail-coverts greyish white; bill black ; feet dark brown.
Total length 31 inches, bill i , wing 2 i, tail 1£, tarsus i .

LEUCIPPUS VIRIDICAUDA, Berlepsch.
Berlepsch’s Whitethroat.

C ount von B e r le fsch has described this species as being different from the Peruvian L . leucogcster by
reason o f its uniform tail-feathers, these never being margined with white, as well as by its shorter bill.
The“typical specimen was obtained by Mr. Henry Whitely at Huiro, in Southern Peru, and Count von
m m remarks concerning it:— “ I have sometimes looked npon this as being the young of L . leucogaster
j a m . but Dr. Taczauowski assures me that he has had many specimens o f / / . leucogaster under his
eyes, and amongst them young birds which already showed the white marks on the inner webs of the outer
rectrices, of which L . mndicuuda has not the slightest trace.”
Dr. Taczauowski thinks the Huiro bird quite distinct; and we do not dissent from the opinion of our best
authority 011 the birds of Peru. [R B S ]
