(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.

Skimmer
Definition:
(n.) One who, or that which, skims; esp., a utensil with which liquids are skimmed.
(n.) Any species of longwinged marine birds of the genus Rhynchops, allied to the terns, but having the lower mandible compressed and much longer than the upper one. These birds fly rapidly along the surface of the water, with the lower mandible immersed, thus skimming out small fishes. The American species (R. nigra) is common on the southern coasts of the United States. Called also scissorbill, and shearbill.
(n.) Any one of several large bivalve shells, sometimes used for skimming milk, as the sea clams, and large scallops.
