Although it averages slightly narrower, there are specimens of Herbstii (No. 470 in our collection, see table) as narrow as some of those from Brazil, referred to this species by Miss Rathbun (in Coll. Yale Mus.). The lateral marginal teeth are a little less oblique and less concave in front, but in some specimens this distinction fails ; indeed, the teeth of opposite sides of one specimen may sometimes differ considerably in outline, or about as much as the species differ in this particular. But in this form the teeth are more thickened at base above, and are rather more granulous at the edges. The fourth and fifth teeth are more squarrose, and the tips are turned upward. The third tooth often differs but little from the
