The distribution of the coverts of the dorsal aspect of the 

 wing agrees with that in other Owls: they form obliquely 

 transverse rows sloping from without inwards instead of 

 being arranged in quincunx. 



The rounded form of the expanded wing shews this bird 

 to be a wood-haunting species. 



8emiplum.ee, Plumce, and Filoplumee : — 



All these agree in their general distribution with what 

 obtains in Owls generally. 



Podotheca. — Clothed with feathers down to the aero- 

 podium, which is invested with reticulated scales, among 

 which filoplume-like feathei's are scattered. 



Claws. — There are no claws on the wing : those of the 

 foot are large, rounded, and curved. The mesial border of 

 the claw of the third digit is produced into a flat, cutting, 

 and slightly serrated edge. 



Uropygium napiform, and not tufted. 



Apteria : — 



Apterium capitis (PI. II. fig. 3). — The apteria of the head 

 are represented by the bare spaces surrounding the eyelids, 

 the spaces on the sclerotic ring of the eye, and a very broad 

 conspicuous space extending on either side of the head from 

 the apt. colli laterale, and terminating on the crown of the 

 head above the middle of the eye. 



Apt. colli laterale. — Traced from the base of the neck this 

 may be followed forwards to the symphysis of the lower jaw, 

 and upwards to the region of the middle of the eye. 



Apt. trunci laterale, spinale, mesogastrm, crurale, and alee 

 superioris and inferioris do not differ materially from those 

 of Asio, and may be studied in the accompanying figures. 



II. Description of the external Ear. 



As will be seen by the figures (PI. II. figs. 1-3), the 

 aperture of the ear (a.e.) is small, oval in outline, and 

 markedly asymmetrical with regard to the aperture on the 

 opposite side of the head. 



On the right side (PI. II. fig. 2) this aperture lies
