Description
Original diagnosis after White (1931) p. 70 [2532]: A species of Hypolophus known only by isolated teeth (and dermal tubercles). Teeth similar in form, arrangement and size to those of the living H. sephen (Forskal), but sides of crown always sloping inwards and overhanging the root, and median lateral teeth of upper jaw relatively wider. (Dermal tubercles variable in size and shape; larger forms longer than wide, with upper surface ornamented with numerous grooves radiating from a small, much elevated central spine sloping backwards, and large root convex and smooth; smaller tubercles similar but rounded, with vertical median spine.)
