  Nemertina  \Nem`er*ti"na\,  n.  pl  [NL.  See  {Nemrtes}.]  (Zo["o]l.) 
  An  order  of  helminths  usually  having  a  long,  slender,  smooth, 
  often  bright-colored  body,  covered  with  minute  vibrating 
  cilia;  --  called  also  {Nemertea},  {Nemertida},  and 
  {Rhynchoc[oe]la}. 
 
  Note:  The  mouth  is  beneath  the  head,  and  the  straight 
  intestine  at  the  posterior  and  They  have  a  very 
  singular  long  tubular  proboscis,  which  can  be  everted 
  from  a  pore  in  the  front  of  the  head.  Their  nervous 
  system  and  blood  vessels  are  well  developed.  Some  of 
  the  species  become  over  one  hundred  feet  long.  They  are 
  mostly  marine  and  seldom  parasitic;  a  few  inhabit  fresh 
  water.  the  two  principal  divisions  are  Anopla  and 
  Enopla.
