Description
Original diagnose after Ward (1984) p. 66 [2495]: (based on isolated male teeth). In occlusal view the crown is oval, the long axis being labiolingual, sometimes with a slightly concave lingual margin. In lateral view the crown base is inflated, forming a rim which is basally concave. The transverse cutting edge is absent, but there is a well developed labial cutting edge. The root is bilobed and widely divergent.
