Einiosaurus procurvicornis and Achelousaurus horneri are two new
"to-be-named" species of ceratopsian dinosaur, closely related to
Pachyrhinosaurus.  Scott Sampson presented these two at the SVP meeting in
Seattle last year.  I don't know when the official publication comes out.

Einiosaurus is the dinosaur refered to as "Styracosaurus makeli" in
_Dinosaurs: A Global View_ by Czerkas and Czerkas.
