Original Description
Shell subspherical or hemi-spherical, with irregular small circular pores with polygonal frames, bearing a sharp three-bladed apical horn. Distinct peristome, from which extends three terminal feet; as extension of L, L and D. Feet stout convexly curved outward, three-bladed in section without notches or branches.
(Based on 7 specimens) Height of cephalis 62-80 µ and maximum width of cephalis 72-110 µ Distinguishing characters (rw): This species is similar to Cladospyris tribrachiata Ehrenberg (1875, pl. 21, fig. 8) but the former is distinguished by possessing an apical horn and three feet without notches or branches. T. simplex is distinguished from T. cassidus as described under that species.
Etymology: simplexis derived from the Latin, meaning simple.
