Asia; the latter, which is called Tengmalm’s Owl, is 
also an occasional but very rare visitor to Great 
Britain. 
The genus Vyctale is followed by other genera of 
small Owls; these are Gise//a, containing a single rare 
species from tropical South America, (G7sella harrisit) 
Microptynx, containing the smallest of the European 
Owls (Microptynx passerina), which is also a native of 
Northern Asia; G/aucidium containing several species, 
all of which are natives of America, and one of which 
(Glaucidium pumilum) is perhaps the smallest Owl in 
existence. Most of these little Owls of the genus 
Glaucidium subsist principally on insects. 
The genus Glaucidium is followed by the genus 
Gymnoglaux, consisting of two species of small and 
somewhat bare-legged West Indian Owls, one of 
which, Gymnoglaux nudipfes, was figured in the “ Ibis” 
for 1859, from specimens obtained in the island of 
St. Croix, and presented to the Norwich Museum by 
Messrs. Alfred and Edward Newton. 
The next genus, Pholeoptynx, contains the curious 
burrowing Owls, which are natives of some parts of 
the American Continent, and also of some of the 
West Indian Islands. These Owls usually inhabit the 
holes made by various rodent quadrupeds, such as the 
Woshee, (Spermophilus douglassii) in British Columbia, 
and the Wishton-wish, (.S. Zdovicianus) on the North 
American prairies.
