MONOGRAPH OF THE OWLS—STRIGIDA. 
straight bill, long legs, very often naked, short toes, short wings, 
live on the ground, good runners. Where we find this character 
we give the third rank, 
These characters are exhibited by Pholeoptyna (A. cunicularia, 
Sceloglaux (T. albifacies), Aenemis (Scops gymnopodus), Ehenop- 
tyna (mewicanus et madagascariensis), Ketupa (B. ceylonensis, 
ketupa, peli flavipes), Scelostria (str. candida), et Bulaca (syrn. 
Indranee, sinense, pogadorum et leptogrammicum). 
Very developed bill, strong claws, long toes, and great voracity, 
give all the subgenera the fourth rank. On account of these cha- 
racteristics, I give Glaucidium (nanum, pumilum, infuscatum, 
ferrugineum) ; Surnia (ulula), Ctenoglaux (scutellatus), Ptilopsis 
(scops leucotis), Urrua (Bubo coromander, orientalis, lacteus) ; Dac- 
tylostrix (Stria castanops et personata) et Pulsatrix (syrn. tor- 
quatum) the fourth rank. 
Very developed banded plumage, long tail, and vegetable nourish- 
ment, are signs of the Galline type. On this account I give 
Taenioptyne (Gl. brodiei) ; Taenioglaua (Athene castaneoptera, 
erythroptera, cuculoides, capensis), Zeraglaua (strenuus, rufus, 
connivens); Megascops (Scops asio, atricapilla, brasiliensis, indica) ; 
Phasmaptynz (Otus capensis), Pseudoptyna (Bubo philippensts), 
Megastrix (str. tenebricosa), the fifth and last rank.
