from The Free On-line Dictionary of Computing (8 July 2008)

derived class
subclass

   <programming> (Or "subclass") In {object-oriented}
   programming, a {class} that is derived from a {base class} by
   {inheritance}.  The derived class contains all the features of
   the base class, but may have new features added or redefine
   existing features.

   The synonym "subclass" is possibly confusing since the derived
   class has a superset of the base class's features.

   Compare {derived type}.
