Gastropoda - Euomphalina - Euomphalidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|J. B. Knight 1941||Very small, subturbinate, minutely phaneromphalous gastropods, without a sinus, slit, or selenizone; whorl profile gently arched between sutures, rounded below on the final whorl; sutures moderately deep; nucleus simple, dextral, not sharply marked off from the succeeding whorls; base rounded, minutely phaneromphalous; columellar lip thin, gently arcuate, slightly reflexed about the umbilicus; parietal inductura very thin or wanting; outer lip gently oblique backwards from the upper suture, nearly straight; ornamentation fine revolving lirae that are frequently of unequal strength owing to the intercalation of new lirae on the later whorls; shell thin, of two distinctly different layers. The holotype measures about 3 mm. in height and 2.2 mm. in width, with a pleural angle of about 41 degrees.|
