Kant Glossary
[L:102] For Kant, concepts are higher "so far as they have other concepts under them, which in relation to them are called lower concepts". Genus and species is defined in terms of this relation between concepts: "the higher concept in regard to its lower concept is called genus, the lower in respect of its higher, species".

Species Definition from Encyclopedia Dictionaries & Glossaries
English Wikipedia - The Free Encyclopedia
In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is one of the basic units of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms  where two individuals are capable of reproducing fertile offspring (hybrids), typically using sexual reproduction. While in many cases this definition is adequate, the difficulty of defining species is known as the species problem. For example, a species complex is a group of closely related species that are very similar in appearance to the point that the boundaries between them are often unclear. Differentiating measures include similarity of DNA, morphology, or ecological niche. Presence of specific locally adapted traits may further subdivide species into "infraspecific taxa" such as subspecies (and in botany other taxa are used, such as varieties, subvarieties, and formae).
