That's _Einiosaurus_ -- _Einiosaurus procurvicornis_, to be exact.
_Achelousaurus horneri_ has bosses like smaller versions of the ones in
_Pachyrhinosaurus_ and is named after Achelous, a character in Greek
mythology who turned himself into a bull and had one of his horns torn
off (by Heracles?). Hence _Achelousaurus_ refers to the hornless
dinosaur, while _Einiosaurus procurvicornis_ is the "bison
lizard with the forwardly curving horn."
