_Hypsilophodon wielandi_ Galton and Jensen, 1979.  Based on a femur found in 
the Lakota Formation of South Dakota.  More material may have been referred 
to this species, but I'm not aware of it.  _H. wielandi_ is usually regarded 
as a _nomen dubium_, but I guess it's worth a second look.

While on the topic of ornithopods, Norman (1998) in his description of 
_Altirhinus_ recognised _Callovosaurus leedsi_ as a valid species, and also 
listed _Cumnoria prestwichii_ as a genus separate from _Camptosaurus_.  This 
was news to me.

And how is _Thescelosaurus_ polyphyletic?  Is this because _T. garbanii_ is 
probably not a true _Thescelosaurus_ species?  AFAIK, there's only one other 
species left in the genus: the type, _T. neglectus_.
