Original Description
Symmetrically elliptical cortical shell stout (its breadth 0.72 its length), having a squarely truncated osculum (its breadth 0.4 equatorial breadth); this osculum surrounded by a fringe of sepaloid spines; triopyline medullary shell obscured by extreme density of outer shell; pores of cortical shell similarly circular and of the same size, closely set and very small (less than 2.2µm); polygonal meshwork raised and lacking sepaloid spines.
