Vou. II, Pr. 11] LOOMIS—A REVIEW OF THE TUBINARES 127 
abdomen are making their appearance under the cover of the 
down. No. 922, June 25, has exposed contour-feathers on 
the interramal space, malar region, lores, orbita, and sub- 
orbital ‘region. Beneath the surface down, the wings and tail 
have assumed definite form and the body, jugulum, and cer- 
vix have become pretty well clothed with contour-feathers. 
Postnatal down has also appeared. No. 919, October 2, has 
thrown off most of the natal down on the pileum, scapulars, 
wings, and upper tail-coverts, and all of it on the tail. Be- 
tween the chin and crissum the down still persists as an outer 
covering. The greater and middle wing-coverts and inner 
secondaries are edged with brown of a more or less grayish 
tint. The scapulars, too, have paler margins, and under cer- 
tain lights these feathers present a grayish appearance. No. 
918, September 28, is almost entirely free from natal down, 
except on the abdomen and posterior portions of the breast, 
where the contour-feathers are hidden. The general color 
aspect of the upper parts is blackish brown. The wings are 
without conspicuous margins. 
The Expedition series contains one hundred and four speci- 
mens in definitive feather, obtained as follows: January, 
three specimens; February, twenty-six; March, one; April, 
seven; May, twenty-eight; June, eighteen; July, two; August, 
seven; September, twelve. The majority of these specimens 
have more or less feather growth in progress, particularly on 
the body, neck, and pileum. Twenty-nine are renewing wing 
and tail feathers as indicated in the following table:
