Diagnosis
ReferenceDiagnosis
P. Broenniman and R. Todd 1954The general outline of the test is subquadrate. The major portion of the test is represented by the three-chambered final volution. The early portion of the test is distinctly trochoid. It is only slightly smaller than the antipenultimate chamber. The subglobular and appressed chambers of the final volution increase rapidly in size, and the end chamber is equal to or only slightly smaller than the preceding part of the test. The ultimate and penultimate chambers are added perpendicularly to the preceding oral face. The initial spiral is indistinct and the spiral side is much like the umbilical side. The umbilicus is very shallow. The arcuate main aperture is situated at the intersection of the umbilical sutures; the smaller. also arcuate. accessory aperture is opposite the main aperture on the spiral side. Additional accessory apertures of the early spiral are visible only in large and well-preserved specimens. The main aperture is bordered by large pustules. The well-defined sutures of the end stage are straight. Those of the initial stage are slightly curved. The walls are finely perforate and the surface is covered with strong and rather uniform pustules. The species coils to the right and to the left. The length of the test ranges from 0.35 mm to 0.6 mm.
