Original Description
Shell smooth, with deep collar stricture. Length of the two joints = 1: 3, breadth = 1: 7. Cephalis spherical, with an oblique conical horn of twice the length and small circular pores. Thorax flatly, conical, twice as broad as high, with straight lateral outline, and regular hexagonal meshes, increasing gradually in size towards the mouth; bars very thin. Peristome or margin of the basal mouth circular, smooth. Very similar to Theopilium tricostatum (Pl. 70, fig. 6), but without abdomen. Differs from the two preceding species mainly in the conical form of the thorax and the less delicate network.

Cephalis 0.03 diameter; thorax 0.1 long, 0.2 broad.

Etymology: + Latin "costatus" (-a, -um) = ribbed
