Description
Original diagnose after Ward (1978) p. 25 [2491]: Alopias known only by isolated fossil tooth. Crown low, triangular, commissurally inclined, inflated and laterally expanded at the base. Root widely divergent and almost entirely covered by the crown. Median groove present, probably well developed.
