Original Description

Shell conical with semi-enclosed irregular and very fine meshwork; numerous triangular to polygonal irregular pores. Sagital ring and constriction absent. A characteristic apical opening is located on a right or left side of the apical part next to one or two conical apical horns and forms a triangular cavity which has occasionally a frame extending from one of the apical horns. A few circular to oval basal pores vary considerably in size from 1/10 to 1/3 of the shell width. Three to four feet are made of the meshwork, ca. 1/8 of the shell length and extending parallel to a plane of the cone.

Length (31 specimens): 567 ± 89 µm (2 S.D.); width (36 specimens): 372 ± 42 µm.

Etymology:
a dimunitive of the word tipi (var. of tepee) because of its characteristic shape.

Editors' Notes
This species is large in size and commonly observed at Station PB, but poor preservation in the sediments is expected due to its fragile skeleton.
