FIGURE 5. Comparison of shell morphology of normal (A) and aberrant (B-D) specimens of Rubyspira brasiliensis sp. nov. A. holotype. B-D. aberrant specimens from the type locality obtained together with the holotype, NSMT-Mo 78945. All at the same scale. Scale = 1 mm. Anomalous relative shell length (L2) and width (W2) were measured as shown in A to compare the proportions of these specimens (Figure 6) because of the incomplete conditions of the apical part and outer lip of some specimens. L2 represents the length between the apical margin of the penultimate whorl and the intersection of the basal part of body whorl and aperture in the frontal view.
