Immature male. — No. 115997, U.S.N.M; James Islaud, Galapagos, 

 Ajiril 11. 1888; C. H. Townsend; type of Cactornis hijpolcHc<(, Bidgway. 

 Above plain light grayish olive, the pileum very indistinctly streaked 

 with darker; wings dusky, with pale grayish olive edgings, the middle 

 and greater coverts edged more broadly with dull buffy. A supercil- 

 iary stripe (becoming obsolete above auriculars), suborbital and malar 

 regions, and entire lower parts dull white tinged with pale buffy on 

 under parts of the body, the under tail-coverts more decidedly so; sides 

 of chest very indistinctly streaked with pale grayish. Bill pale yellow- 

 ish brown (the mandible lighter and more yellowish), darker at tip ; legs 

 aud feet blackish browu. Length (skin), 5.70; wing, 2.95; tail, 1.80; 

 culmen, 0,77; gonys, 0.39; bill to rictus, 0.70; width of mandible at 

 base, 0.31; depth of bill at base, 0.39; tarsus, 0.90; middle toe, 0.(;S. 



Adult (?) female. — No. ~)52., collection of Dr. G. Baur; James Island, 

 Galapagos, August 10, 1891. Similar to the immature male, as de- 

 scribed above, but with very distinct and rather broad streaks of gray- 

 ish olive on chest, sides, aud Hanks. Length (skin), 1.45; wing, 2.72; 

 tail, 1.64; culmen, 0.70; gonys, 0.38; width of mandible at base, 0.30; 

 depth of bill at base, 0.39?;' tarsus, 0.92; middle toe, O.GO. 



An immature male from Jervis Island in Dr. Baur's collection (Xo. 

 409, August 8, 1891) is very similar to the James Island specimen 

 described above, but is appreciably more olivaceous above, has the under 

 parts distinctly tinged with pale buffy yellowish, and is slightly smaller, 

 its measurements being as follows: Length (skin), about 4.80; wing, 



' The bill is not tightly closed, and this measurement therefore only approximately 

 correct.
