The exact size, configuration and dentition of the basal margin is characteristic and affords a means for separating the species. The absence of the right lateral ridge has seemingly effected a slight shift in the position of the right subumbral canal. Its insertion on the circular canal lies just above the right lateral tooth (mentioned below), but thence it bends rather sharply ventrad and comes to lie below the right ventral wing. It follows the sinuous course of the latter toward the apex where it joins the apical canal in a normal way. The other three canals are in their usual position. There are five robust triangular oral teeth which are usually ser- rated. The two lateral ones curve inward toward the opening of the.
