(n.) 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.
(n.) 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.

Lemur
Definition:
(n.) One of a family (Lemuridae) of nocturnal mammals allied to the monkeys, but of small size, and having a sharp and foxlike muzzle, and large eyes. They feed upon birds, insects, and fruit, and are mostly natives of Madagascar and the neighboring islands, one genus (Galago) occurring in Africa. The slow lemur or kukang of the East Indies is Nycticebus tardigradus. See Galago, Indris, and Colugo.
