type image: T. tripodiscusOriginal description: Shell campanulate, smooth, as broad as long, with deep sagittal stricture. Cephalis compressed, with irregular roundish pores; two or three pairs of larger annular pores on each side of the ring. Basal plate with four large pores. Galea with two very large opposite holes (an occipital and a frontal opening). A slender free perpendicular columella connects the uppermost part of the sagittal ring with the strong three-sided pyramidal apical horn. All three feet of equal length, half as long as the ring, three-sided, prismatic, divergent, with three dentated edges.
Remarks on original description: Haeckel listed Tholospyris tripodiscus under the subgeneric name Tholospyrium, but did not include the subgeneric name in the species name.[comment from RadWorld database]
