 398. P. nut'talli. (To Thos. Nuttall.) Nuttall's Pook-will. $ ? , adult : Assuming the 

 upper parts of a beautiful bronzy-gray ground color, this is elegantly frosted over with soft 

 silver-gray, and watered in wavy cross-pattern with blackj these black double crescents enlarg- 

 ing to herring-bone marks on the scapulars and inner qniUs. Four middle tail-feathers patterned 

 after the back ; others with firmer black bars on motley brown ground, and short white tips. 

 Primaries and longer secondaries bright tawny, with pretty regular black bars, and marbled 

 tips (the half-opened wing viewed from below is curiously like that of the short-eared owl.) 

 A large firm silky-white throat-bar. Under parts grounded in blackish-brown, giving way 

 behind through oehrey with dark bars to nearly uniform ochrey. It is impossible in words to 

 give an idea of the artistic blending of the colors in this elegant little night-jar. The sexes

 much shorter than the extremely long, pointed, stiff, and thin-bladed wing, with 1st primary

 heavily colored. Not strictly nocturnal. Remarkably volitorial.
