with pale olive-brownlsli on sides and flanks. Maxilla light tawny, 

 darker and more brownish terminally, especially on cnlmenj mandible 

 ligliter, approaching ochraceous-yellow; legs and feet grayish black. 

 Length (skin), 4.G0; wing, I'.GS; tail, 1.7S; cnlmen, 0.67; gonys, 0.32; 

 width of mandible at base, 0.33; depth of bill at base, 0.42; tarsus, 

 0.88; middle toe, 0.63. 



Aclulf female f. — Same collection, etc. Similar to the supposed imma- 

 ture male, but rather darker and much grayer above, with dark streaks 

 on pilenm broader and lighter, margins of wing-coverts light brownish 

 gray on middle row and faintly buflfy grayish on greater series ; under 

 parts much less yellowish, the color being buffy Avhite, tinged with pale 

 brownish laterally, where very obsoletely streaked (rather broadly) with 

 pale brownish gray; bill not quite so bright in color. Length (skin), 

 4.45; wing, 2.65; tail, 1.65; culmen, 0.64; gonys, 0.33; width of man- 

 dible at base, 0.34; depth of bill at base, 0.44; tarsus, 0.90; middle 

 toe, 0.02. 



Another supposed adult female in Dr. Baur's collection is similar in 

 color to the one described except that the whitish of the face and under 

 parts is slightly more yellowish. It is also slightly larger, its measure- 

 ments being as follows: Wing, 2.73; tail, 1.70; culmen, 0.68; gonys, 

 0.32; width of mandible at base, 0.34; depth of bill at base, 0.44; 

 tarsus, 0.87; middle toe, 0.61. 



The specimens above described were skinned from alcohol, and it 

 was found imi)ossible to determine their sex, having been eviscerated 

 before their preservation. It is therefore possible that the supposed 

 immature male is in reality an immature female. It certainly is not a 

 very young bird. That the other two are adult females I think there 

 can be no reasonable doubt. 



This bird is so closely related to C. habeli of Abingdon Island, that I 

 have hesitated long before separating it; but the decidedly broader 

 culmen and somewhat difl'erent shape of the bill and the slight, though 

 apparently constant, color-characters mentioned seem to warrant its 

 recognition as a local form.
