Up to the present time we have not found the first subgenus in 
the first genus Glaucidium. 
The first subgenus in the second genus Nyctale will be found in 
the Museum of Leyden. The species was mentioned to me verbally 
by Prince Ch. Bonaparte. 
The first subgenus Microglaux of Athene, and the first subgenus 
Microptyna of Surnia, are the smallest in their genera, and haye 
the first wing-feather shorter than the tenth. The first subgenus 
in the genus Zeraglaux, with the same characters, is yet undis- 
covered. In the second subfamily Strigine, Pisorhina (manadensis) 
has certainly the first wing-feather shorter than the tenth, because 
all the subgenera Pseudoscops, Lophostrix, Phodilas, and Ovecaba 
have the same characters, and also naked toes with scales. 
The subgenera of the second rank have asymmetric ears, longer 
Wings, only emarginated towards the end, and broad felted inner 
webs; they are nocturnal, 
With these characters, I give the second rank to the subgenera 
Nyctale (acadica, funerea) ; Athene (noctua, meridionalis, brama ; 
Nyctea (8. nyctea) ; Spiloglaux (boobook, maculatus, marmoratus 4 
Nove zelandiw) ; Scops (ephialtes, senegalensis, pennata) ; Otus 
(vulgaris, americanus, zonurus); Bubo (bengalensis, maximus, asca- 
laphus, africanus, virginianus); Strix (punctatissima, jlammea, 
perlata, delicatula) Syrnium (nivicolum, aluco, cinereum, nebu- 
losum et uralense). 
The characters of the subgenera of the third rank are—long,
