PELICANIDiE. 
Succeeding the family of the Auks, very limited in 
numbers in every part of the world, and comprising 
only seven species that can rank as British, we 
pass to the group of the Cormorants and Solan Geese, 
of which we possess only two forms, represented hy 
three species. These birds are still prominently 
aquatic, seek their whole food under the water, and 
are extremely voracious ; some breed gregariously 
on precipitous rocks in the vicinity of the sea ; but 
the Cormorants often travel inland, and perch and 
sleep on trees ; the latter form the 
Genus Pualacracorax, Brisson. — Generic cha- 
racters. — Bill long, straight, slightly com- 
pressed, maxilla terminating in a powerful 
hook, furrowed laterally to the tip ; nostrils 
basal, concealed, base naked ; wings rather 
short, second or third quill longest ; legs placed 
behind ; tarsi short, strong, but ample ; four 
toes, all connected, the outer longest, others 
gradually shortened. 
Types. — P. carlo, #c. Cosmopolite. 
Note . — Undergo a seasonal change ; migrate par- 
tially inland in winter ; perch on trees ; capable 
of domestication ; trained to fish.
