 the primaries white very faintly tinged with yellow. 



Tijpe.— V. S. N. M. 212,479. Male. Polynesia: Marquesas; 

 Nukuhiva, 15 September, 1899.

 deep olive to dark olive, this color merging into a broad margin of 

 light yellowish olive; neck, back, and scapulars between yellowish 

 olive and dark greenish olive, this color changing to light yellowish 

 olive on the tips of the feathers on back and scapulars, on rump 

 changing to deep colonial-buff; upper tail coverts light brownish 

 olive with margins more yellowish ; feathers of wings and tail fuscous 

 black; primaries edged with light yellowish olive; secondaries edged 

 broadly with colonial-buff and primaries and secondaries tipped with 

 marguerite-yellow; wing coverts fuscous, margined broadly with 

 colonial-buft'; rectrices tipped with marguerite-yellow, the tips 

 broader on the external feathers, lessening in extent, especially on the 

 inner webs, toward the central pair; outer pair with a very narrow 

 obscurely indicated paler margin for distal half; under surface, save 

 abdomen, barium-yellow to citron-yellow; center of abdomen white; 

 lores whitish; superciliary stripe, malar and auricular region, and 

 bend of wing strontian-yellow; under wing covers naphthalene-

Measurements. — Seven males wing 98.6-103.0 (100.5) ; tail 86.2-

Remarks. — This species is represented by nine skins, two mummies, 

 and an alcoholic specimen secured at Nukuhiva, 15, 16 September, 

 1899. The series is remarkably constant in coloration, there being 

 no tendency toward albinism such as is often found in the island 

 inhabiting species of this genus. The seven birds that have the sex 

 determined are males. 



No specimens of Conopoderas niendanae (Tristram) are aA'ailable for 

 comparison, but an excellent description is found in the Catalogue 

 of birds in the British museum, 1883, 7, p. 526, and with the original 

 description of Canon Tristram (Ibis, 1883, p. 43) is given a colored 

 figure that shows the characters of the bird distinctly. In this plate
