it may be at the same time very tame (Brehm). This Owl makes grimaces which 
usually much entertain the spectator, and possesses the remarkable faculty of dilating 
the feather-wreaths to such an extent, that over each eye is formed an elevated pro- 
tuberance, which gives the appearance of two little feather-horns. Its flying is like the 
Otus vulgaris, but the strokes of the wing follow more quickly (Nawmann). It lays four 
round white eggs, which Brehm describes as with smooth surface and few pores. 
One of these was 1 inch 5 lines long, and 1 inch 23 lines broad.

It has nearly the same dimensions (wings 164, tail 96) as N. funerea (wings 163, 
tail 100-103). The only difference is a darker colour on the upper parts, and this is 
the reason that the white spots are more distinct. The character ‘‘ longer tail” is not 
correct. 
This is certainly not a true species.

Diagn.—The nostrils are situated on the margin of the swollen short cera (Plate 
LVI. fig. 3). Ear-orifice small. Wings moderately long, reaching nearly to the end 
of the short tail. ‘Toes naked, with a few bristle feathers. The emarginations on the 
lower jaw not so distinct. These birds are very nearly connected with the first genus 
(Glaucidium), and the fifth genus (Ieraglaux), and are spread over the whole world. 
Subgenus a. Cephaloptyna. 
Diagn. —The first wing-feather shorter than the tenth. First, second, and third very 
clearly emarginated, fourth not so distinctly. The plumage not banded, but much 
spotted.

Descr.—A little larger than Athene noctua, with larger head and stronger bill. Front, 
a stripe over the eye, the whole chin, belly, tarsi, and under wing-coverts pure white. 
The lorum-feathers mixed with blackish bristles, and with black shafts, reach to the end 
of the yellowish bill. Ear-coverts brownish-rufous, spotted at the end of each feather.
