DEFINITIONS

UROSTICTE
(Trochilidae; Ϯ Purple-bibbed Whitetip U. benjamini) Gr. ουρα oura  tail; στικτος stiktos  spotted  < στιζω stizō  to tattoo; "UROSTICTE BENJAMINI.  White-tip.  ...  THIS beautiful species, one of the late discoveries in this lovely tribe of birds, differs in so many particulars from every other member of the family, that I have been constrained to give it a new generic title, and have selected that of Urosticte as indicative of the conspicuous white terminations of the four central tail-feathers; in nearly every other instance it is the outer feathers that are thus marked, and not the central ones, and it is the circumstance of the latter being thus decorated in the present bird which renders it so remarkable." (Gould 1853); "Urosticte Gould, Monogr. Trochil., pt. 6, 1853, pl. [3] and text [= 3, pl. 190 of volume]. Type, by monotypy, Trochilus benjamini Bourcier." (Peters 1945, V, 85).
