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 UcayaH. 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 of the original description : — 



"Crown of the head, nape, shoulders, back, and upper tail-coverfs green ; tail-feathers bluish green, with 

 a feint zone of darker green near the end ; the extreme tij) of all but the two central 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 of the outer web ; wings purplish brown ; breast greyish white, 

 with an obscure spot of dull green 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 3| inches, l)ill i, wing 24, tail U, tarsus i."

LEUCIPPUS VIRIDICAUDA, i?er/.y>.c/^ 



Berlepsch's Whitethroat. 



Leucippus viridicauda^ Beiiepsch, Ibis, 1883, p. 493. — Tacz. Orn. du Perou, i. p. 399 (1884) 



Count von Berlepsch luis described this s|)ecies as beiiig* different from the Peruvian L, leucogaster by 

 reason of 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 

 Berlepsch remarks concerning it : — " I have sometimes looked upon this as being the young of Z'. lencogaster 

 (Tschudi) ; but Dr. Taczanowski assures me that he has had many specimens of//, 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. mridicauda has not the slightest trace." 



Dr. Taczanowski thinks the Huiro bird quite distinct; and we do not dissent from the opinion of our best 



authority on the birds of Peru.
