plete prenuptial moult and my observations indicate that breeding 
does not begin until the adult plumage has been acquired.

(Las Barrancas) to L^rbana or about the mouth of the Apurie River. 
An adult male had the eye sepia brown ; bill, blackish slate above, 
plumbeous below: feet, slaty. The colors of an adult female were: 
eye pinkish cream color ; bill greenish drab with a dusky line along 
ridge of culmen ; feet pinkish; flesh white. 
On May 10, 1898, I took a nest of this species containing one 
nearly fully fledged young and one addled egg. The nest was placed 
among the tops of a thick clump of canes, about 2.13 m. above the 
ground. It is a large loose structure of broad grasses, sedge and 
twigs without a particularly soft lining. The single egg reminds one 
of a large Carpodacns egg. being light greenish blue, with a few minute 
purplish black spots near the tliick end. It measqre^ 24 x 17.5 mm.'
