Diagnosis
ReferenceDiagnosis
K. Bandel 2007Growth of the shell is allometric with increasing relative length of the outer lip in comparison to the height of the spire. During juvenile growth the outer lip expands in posterior direction and reaches the apex before the shell is fully grown. During further growth whorls may cover the whole shell and increase the apical angle. Whorls of the spire are rounded and have a fine ornament of low axial ribs and fine spiral lines besides occasional varices. The inner lip is narrow in front and has a callus pad next to the posterior part of the outer lip. Growth is terminated with the outer lip of the body whorls expanded outward and posterior callus pad thickened forming the margin of a narrow fissure to the end of the outer lip on the spire. The whorls of Orthaulax inornatus remain visible and a fine spiral ornament covers the base of the body whorl
