genus Bubo. I consider in the subgenus Ketupa—Bubo pelii* as 
the typical species of this subgenus and the whole genus Budo. 
Ketupa gives the whole genus Bubo with the largest forms the third 
rank. 
My arrangement now extends further. 
A. Surnina. 1. Glacidium, 2. Nyctale. 3, Athene. 
B. Strricina. 1. Scops. 2. OTUS. 3. Bubo. 
Enormous yoracity, great development of the claws, often pec- 
tinated on the middle toe, is a sign of the Rapaces or Pelicanide 
type. P 
Immense yoracity, very strong and curved claws, a rudimentary 
cere, like the fourth family Gypaétidae we see in the genus Surnia, 
and we give it the fourth rank. It shows some analogies with the 
true Falco, fourth genus of the Falconine. 
Most enormous voracity, and a pectinated middle claw we find 
yet only in the genus Strix, and we give Sériz in the second sub- 
family the fourth rank. It shows, like the fourth subfamily Gypaé- 
tide, the longest and the most ugly skull. 
My arrangement of the genera now approaches its close. 
A. Surnina, 1. Glaucidium. 2. Nyctale. 3. Athene. 4. Surnia. 
B. Stricina. 1. Scops. 2.OTus. 3. Bubo. 4. Strix. 
Very developed plumage, with a great number of bands, long 
banded tail, and vegetable nourishment, is a sign of the Galline type. 
We find in the Australian species of my genus Zeraglaua, a 
great development of the plumage, very long banded tail; and in 
the last subgenus Zeraglaux (Z. strenuus), Mr, Gould mentions 
having found berries in the stomach. On this account I give Zera- 
glaux the fifth rank. 
In the subfamily Strigine, we find in the genus Syrniwm a very 
developed banded plumage and a yery long tail. It is possible 
that we may find, at some future time, vegetable nourishment also 
Mm the last subgenus of this genus. 
id Ch. Bonaparte takes this species to be a proper genus Megapelia ; but Tam 
(ite certain that it is only a species of the subgenus Ketupa, and that it is a true 
ee by a strong comparison of the wings, legs, and nails.
