Cuass II. RED THROATED DIVER. 
These birds frequent our seas, lakes, and 
rivers in the winter. On the 7’hames they are 
called sprat loons, for they attend that fish 
during its continuance in the river. They are 
subject to vary in the disposition and form of 
their spots and colors; some having their necks 
surrounded with a speckled ring; in some the 
spots are round, in others oblong.

gant than that of the others. The weight is three 
pounds ; the length, to the tail end, two feet; to 
that of the toes, two feet four inches; the breadth
