Ch. — Head with a full though short depressed occipital crest. Bill broad , much depressed ; sides nearly straight ; greatest 

 width equal to the length of culmen. Rictua with short bristles. Nostrils oval, margined by membrane, except below. Tarsus 

 shorter than the middle toe, scutellate ; a few feathers on its upper extremity anteriorly ; outer toe a little longer than inner, 

 about equal to the hinder ; hind claw not half the total length of the hind toe. Tail longer than the wings ; slightly forked, 

 but the lateral feather nearly .20 of an inch shorter tlian the next ; the feathers narrow linear. First primary about one fourth 

 the longest ; the second and third much graduated and acuminate ; the fourth longest and rounded. 



I introduce the description of the genus Ptilogonys here to show its relationship to the United 

 States species, especially, too, as the F. cinereus, the type, will most ^probably be found within 

 our own territories. -
