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. Rictus 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 than 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 Uni ted 
States species, especially, too, as the P. cinereus, the type, will most probably be found within 
our own territories. 2

two fifths the fifth, or longest. Tail feathers broad, widening to the rounded tip ; the tail moderately graduated ; the middle
