Diagnosis Test elongate, conical in the early stage or throughout, or later stage may have nearly parallel sides, microspheric generation with a whorl of three chambers, then biserial, and finally uniserial for the major part of the test, megalospheric test with much reduced early stage of a few biserial chambers, and then uniserial, commonly with numerous low dishlike chambers, but in some species the later chambers are higher and slightly inflated, sutures in the uniserial stage straight and horizontal and may be incised, flush, or elevated; wall calcareous, aragonitic, hyaline, relatively thick, finely perforate, surface smooth to finely hispid; aperture in the early stage as in Conorboides, becoming an arcuate slit in the uniserial chambers, those of successive chambers changing about 65¡ in orientation, reflecting the earlier trochospiral coiling, internally a scroll-shaped tooth plate extends from one margin of the slitlike aperture across the chamber lumen to the preceding septum.
