Webster's 1913 Dictionary
  1. Note: In the mouth of bloodsucking leeches are three
          convergent, serrated jaws, moved by strong muscles. By
          the motion of these jaws a stellate incision is made in
          the skin, through which the leech sucks blood till it
          is gorged, and then drops off. The stomach has large
          pouches on each side to hold the blood. The common
          large bloodsucking leech of America ({Macrobdella
          decora}) is dark olive above, and red below, with black
          spots. Many kinds of leeches are parasitic on fishes;
          others feed upon worms and mollusks, and have no jaws
          for drawing blood. See {Bdelloidea}. {Hirudinea}, and
    3. (Surg.) A glass tube of peculiar construction, adapted for
       drawing blood from a scarified part by means of a vacuum.
    {Horse leech}, a less powerful European leech ({H[ae]mopis
       vorax}), commonly attacking the membrane that lines the
       inside of the mouth and nostrils of animals that drink at
       pools where it lives.
  2. \Spe"cies\, n. sing. & pl. [L., a sight, outward
    appearance, shape, form, a particular sort, kind, or quality,
    a species. See {Spice}, n., and cf. {Specie}, {Special}.]
    1. Visible or sensible presentation; appearance; a sensible
       percept received by the imagination; an image. [R.] ``The
       species of the letters illuminated with indigo and
       violet.'' --Sir I. Newton.
             Wit, . . . the faculty of imagination in the writer,
             which searches over all the memory for the species
             or ideas of those things which it designs to
             represent.                            --Dryden.
    Note: In the scholastic philosophy, the species was sensible
          and intelligible. The sensible species was that in any
          material, object which was in fact discerned by the
          mind through the organ of perception, or that in any
          object which rendered it possible that it should be
          perceived. The sensible species, as apprehended by the
          understanding in any of the relations of thought, was
          called an intelligible species. ``An apparent diversity
          between the species visible and audible is, that the
          visible doth not mingle in the medium, but the audible
          doth.'' --Bacon.
    2. (Logic) A group of individuals agreeing in common
       attributes, and designated by a common name; a conception
       subordinated to another conception, called a genus, or
       generic conception, from which it differs in containing or
       comprehending more attributes, and extending to fewer
       individuals. Thus, {man} is a species, under {animal} as a
       genus; and man, in its turn, may be regarded as a genus
       with respect to {European}, {American}, or the like, as
    3. In science, a more or less permanent group of existing
       things or beings, associated according to attributes, or
       properties determined by scientific observation.
    Note: In mineralogy and chemistry, objects which possess the
          same definite chemical structure, and are fundamentally
          the same in crystallization and physical characters,
          are classed as belonging to a species. In zo["o]logy
          and botany, a species is an ideal group of individuals
          which are believed to have descended from common
          ancestors, which agree in essential characteristics,
          and are capable of indefinitely continued fertile
          reproduction through the sexes. A species, as thus
          defined, differs from a variety or subspecies only in
          the greater stability of its characters and in the
          absence of individuals intermediate between the related
    4. A sort; a kind; a variety; as, a species of low cunning; a
       species of generosity; a species of cloth.
    5. Coin, or coined silver, gold, ot other metal, used as a
       circulating medium; specie. [Obs.]
             There was, in the splendor of the Roman empire, a
             less quantity of current species in Europe than
             there is now.                         --Arbuthnot.
    6. A public spectacle or exhibition. [Obs.] --Bacon.
    7. (Pharmacy)
       (a) A component part of compound medicine; a simple.
       (b) (Med.) An officinal mixture or compound powder of any
           kind; esp., one used for making an aromatic tea or
           tisane; a tea mixture. --Quincy.
    8. (Civil Law) The form or shape given to materials; fashion
       or shape; form; figure. --Burill.
    {Incipient species} (Zo["o]l.), a subspecies, or variety,
       which is in process of becoming permanent, and thus
       changing to a true species, usually by isolation in
       localities from which other varieties are excluded.
Biology Dictionary
 Definition: Groups of populations (which are groups of individuals living together that are separated from other such groups) which can potentially interbreed or are actually interbreeding, that can successfully produce viable, fertile offspring (without the help of human technology). [Ernst Mayr, 1969] The species is the most fundamental unit of evolution and is the most specific taxonomic level.
  1. A classification of related organisms that can freely interbreed.
  2. the largest natural population whose members are able to reproduce successfully among
