only the holotype

Original diagnose after PLEDGE, 1992 [1918]: An Echinorhinus with relatively high and erect main cusp; mesial and distal secondary cusps pointing upwards and divergent; mesial cusp slightly larger than distal one; and a pair of minute basal cusps mesially and distally. The specimen differs from all described species (Pfeil, 1983 [1886]), except E. cookei and E. pfauntschi, in size and orientation of main cusp; from all species, except possibly E. blakei, in orientation and size of mesial and distal secondary cusps; and from all species in relative positions of mesial and distal secondary and basal cusps.
