 ascending and convex, the edges sharp and inflected, the tip obtuse, but like 

 the upper thin-edged. Head rather small, oblong; neck of moderate length; 

 body full. Feet rather short, stout; tarsus roundish, feathered, bare and 

 reticulated behind. Toes of moderate size, covered above with numerous 

 scutella, laterally pectinated with slender projecting flattened scales; first

 those on the head very short, on the sides of the neck anteriorly at its lower 

 part and across the fore part of the breast, small, very short, broad, stiff, and 

 imbricated like scales; higher up on the sides of the neck a tuft of feathers 

 having their shafts elongated, bristle-like, and terminated by a few filaments. 

 On each side of the lower part of the neck in front is a large bare space 

 capable of being inflated into a hemispherical sac. On the fore part of the 

 breast the feathers, although long, have the shaft thickened and elongated; 

 the rest of the feathers are of ordinary structure. Wings rather short, con- 

 cave, much rounded, the primaries stiff and very narrow, so as to leave a 

 large interval when the wing is extended; the third, fourth, and fifth quills 

 longest. Tail long, graduated, of twenty stiffish feathers, each tapering to a 

 very elongated point.

 inner webs nearly plain brown. The throat and fore part of neck whitish, 

 longitudinally spotted with brownish-black; a narrow white band across the 

 throat; the sides of the neck and fore part of the breast white; the elongated 

 shafts of the tuft-feathers black; the sides variegated like the back, with a
