Carinaevenly curved, its apex projecting freely for a short distanceand touching or entering between the terga, its base roundedand widely separated from cariual latera; roof stronglyCJnvex, defined by a slight ridge on each side from the Barnacles of the Genus Scalpellum. 117 narrow parietes (holotype) or slightly convex, formingprominent angles with the parietes (paratype).

Inframedian latus small, triangular, set obliquelywith the apex near the surface and the base deeply latus also set obliquely, much broader than high,with umbo in line with upper margin, recurved and slightlyprojecting laterally but hardly posteriorly, not meeting itsfellow below the carina (fig. 5, D).
