both webs of the middle pair being dusky; outer webs of all tlie rec- 

 trices edged witli light olive-green. Whole side of head (including 

 superciliary region) and entire under parts rich yellow, becoming paler 

 (canary yellow) posteriorly, on under wing coverts and edges (broadly) 

 of inner webs of remiges; chest and sides of breast marked with broad 

 streaks (more or less cuneate or sagittate anteriorly) of rather light 

 orange-chestnut, the sides and Hanks with still narrower and paler 

 streaks of the same. Bill blackish (in dried skin) with paler tomia; 

 legs and feet brownish.^ Length (skin), 4.70; wing, 2.55; tail (much 

 worn), 2; exposed culmen, 0.48; tarsus, 0.85; middle toe, 0.48. 



Adult female.— Eo. 125901, U.S.KM.; Chatham Island, March 30, 

 1801, C. H. Townsend. Altogether duller colored than the adult male. 

 Above plain olive-green, becoming more yellowish on forehead ; wings 

 and tail as in adult male, but dusky color not so dark, and yellow 

 edgings, etc., rather less sharply contrasted; superciliary stripe (wider 

 and clearer in color on sides of forehead) and entire under parts clear 

 yellow, rather less intense than in adult male, the under parts without 

 trace of orange-chestnut streaks. Length (skin), 4.90; wing, 2.38; 

 tail, 1.80; exposed culmen, 0.42; tarsus, 0.80; middle toe, 0.45. 



Young {malef).—^o. 115904, U.S.N.M.; Charles Island, April 8, 

 1888; C. H. Townsend. Pileuin and hind neck dull gray, the crown 

 strongly tinged with olive-green; rest of uj^per parts grayish olive- 

 green; wings and tail as in adult male, but yellow edgings paler, on 

 terminal half or more of secondaries and ends of primaries passing 

 into dull buffy whitish; under parts dull bufly white, tinged with olive- 

 gray on sides and flanks and with pale yellow on anal region and under 

 tail-coverts. 



1 am unable to appreciate any constant ditferences between speci- 

 mens from the several islands. Immature birds exhibit every interme- 

 diate condition of i)lumage between the earliest stage, with dull white 

 under parts and ashy gray hind neck and the full adult dress, as 

 described above. 



Although said to occur on the coast of Ecuador and Peru, I have 

 not seen a specimen from any part of the mainland. Two adult males 

 collected on Cocos Island by Mr. Townsend appear to be quite identical 

 with Galapagos examples. 



"'Legs flesh color, yellow behind; soles of feet yellow; hill dark brown above, 

 bluish olive below." fAdanis, MS.) Unfortunately it is not stated whether the 

 specimen from which the notes were taken was an adult male or otherwise.
