276 NAKED* FOOTED NIGHT OWL. 
clothed with sparse bristly plumes on their upper 
surface. In the wings, the longitudinal proportion 
of the quills does not much vary, hut in Teng- 
inalmi the feathers are soft and broad, the two 
first only notched, and the whole wing shewing 
the provision for noiseless and sustained flight; 
in nudipes, the quills are narrow and stiff, the

the structure more adapted for a swift flight. 
The plumage of this species, to a certain degree, 
resembles the last ; the disk is grayish white, 
mottled with liver brown, particularly beneath the 
eyes, but it wants the dull black feathers covering

ending in an oval spot of the same colour ; on the 
back of the neck and scapulars, the feathers are 
white, margined with liver brown, and at the base 
of the same tint; on the nape, the white is most pre-

united webs of one feather lying over the white 
portion of the one before it, gives a clouded 
appearance to these parts, from the light colour 
shining through. The quills are marked with 
yellowish white bars on the outer webs ; on the 
inner, with large yellowish or ochraceous white
