Extra details from original publication
There are specimens from Mexico in the United States National Museum collections which seem identical with this species. They are from fine sandy clay, Rio Buena Vista, just south of crossing of Alazan to Moyutla road, Vera Cruz; fossil horizons 3 and 4; light gray sandy clay, Rio Tuxpan, south side just above Agua Nacida, Vera Cruz, all three lots collected by T. W. Vaughan. This is the most delicate of the various species.

It is very abundant at the type locality and occurs in other parts of the Coastal Plain in the Upper Eocene.
