Definition: A class of objects divided into several subordinate species;
a class more extensive than a species; a precisely defined and exactly
divided class; one of the five predicable conceptions, or sorts of
terms.
Definition: An assemblage of species, having so many fundamental points
of structure in common, that in the judgment of competent scientists,
they may receive a common substantive name. A genus is not necessarily
the lowest definable group of species, for it may often be divided into
several subgenera. In proportion as its definition is exact, it is
natural genus; if its definition can not be made clear, it is more or
less an artificial genus.
