56 The Official Guide to the 
Palawan in the Indian Ocean; the beautiful Owls of 
the American genus Czcaba, C. nigrolineata, and C. 
huhula, the former from Mexico and the latter from 
the Upper Amazon should not be passed over. 
Case L. 
introduces us to the genus Syruzwm, among which 
should be noted S. a/lenz from Florida, and S. occ- 
dentale, a single specimen obtained in California. At — 
the bottom of the case will be seen a fine series of 
the European Brown Owl (S. a/zco), much persecuted 
by game preservers, but still found in our own woods 
as well as dispersed over most of the continent of 
Europe and some parts of North Africa and Asia. 
The Ural Owl is, as its name indicates, from the Ural 
Mountains. 
Case LI. 
commences with the Lapp Owl, a magnificent species, 
of which there is a grand series, for the most part 
collected in Lapland by the late John Wolley; these 
are followed by the equally beautiful Snowy Owl 
WNyctea nivea (scandiaca) an inhabitant of most of the 
northern portions of Europe, Asia, and America, 
and occasionally visiting Great Britain, and even our 
own county; local specimens will be seen in the 
British collection. ‘Then follow the Owls of the 
genus /Vycta/a, including Tengmalm’s Owl, an occa- 
sional visitor to Britain; it has occurred three times 
in Norfolk, but its true home is the forests of 
Scandinavia and Russia. Guzsella harrisi, Harris’s 
Owl, is a rather uncommon species from Bogota, South 
America; a pretty little owl known as Whitney’s 
Owl from Lower California; and this is followed by 
Microptynx passertina, the smallest of European Owls.
