This  kind  of  slug  is  nocturnal^  but  very  active.  Its
slime  is  abundant  and  stains  linen  of  a  yellow  colour.
It  appears  to  be  fond  of  breads  cooked  vegetables^  and  all
sorts  of  kitchen  refuse.
It  is  probable  that  the  L.  flamta  of  Miiller  may  be  a
variety  of  Arion  ater,  because  he  describes  the  shield  as
not  having  any  concentric  wrinkles^  although  in  the
same  description  he  also  notices  a  yellow,  slug  which
seems  to  belong  to  the  present  species.  This  is  the
L.  variegatus  of  Drapamaud ;  and  its  shell  is  probably
the  lAmaceUa  cancava  of  Brard.
