Diagnosis Test elongate fusiform, circular to oval in section, initial end pointed and commonly with a basal spine, inflated chambers in a twisted biserial arrangement, increasing rapidly in relative height as added, final pair occupying over half the test length, sutures slightly oblique, depressed; wall calcareous, optically radial, perforate, pores of medium size, surface smooth; aperture a broadly oval interiomarginal opening occupying most of the apertural face, one margin with a low rim, the other bending inward to form an internal toothplate like that of Stainforthia, spoonlike in form and nearly closing the apertural opening, the free part almost reaching the opposite apertural rim but not protruding above the apertural level. Pliocene to Holocene; Europe; North America; Atlantic; Pacific. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
