, found in Lower Carboniferous sediments in Europe, and named by Hyatt, 1893. The shell of ''Lophoceras'' is evolute, large, with a slight impressed zone on the inner rim.

The suture has an angular ventral saddle, broad shallow lateral lobe, and a dorsal lobe. Except for growth line, the shell is smooth.
