Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. B. Knight 1941 | Very small, fusiform, anomphalous gastropods without sinus or slit and withasiphonal notch; whorl profile between sutures flat; sutures at ephebic stages scarcely visible, at neanic stages sharply incised; nucleus of two whorls flattened on top, with strongly arched whorl profile, the first whorl slightly tilted in some specimens; base pointed, extended, anomphalous; columellar lip merging with the parietal lip, very gently arched and with a distinct anterior siphonal notch bordered above on the columella by a highly oblique and obscure siphonal fold, the united columellar and parietal inducturas slightly thickened; outer lip very slightly oblique backward and convex forward; whorls very high at ephebic stages; columella as shown in section very thin, seemingly through partial resorption; ornamentation wanting; shell structure not distinctly double layered; earlier whorls not partitioned off. The holotype measures 4.35 mm. in height, 1.10 mm. in width, and has a pleural angle of about 15 degrees. |
