Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. O. Cernohorsky 1971 | Species of Notadusta differ from Notoluponia in features of a declivious labial lip in the anterior region, the prominent posterior canal and the smooth columella which is not crossed by the columellar teeth. | |
| L. Dolin and P. Lozouet 2004 (Ransonia) | La coquille (Fig. 5a-5c) est oblongue, a bards peu calleux, arrondis. T .a spire est saillante au centre d'une aire pseudombiliquee. Le canal siphonal est profond, formam un pontet court, annulaire, clans le plan de la sole ventrale. Le pli terminal est legerement courbe, formam un meplat presque horizontal, en croissant de June, borde par un funicule en position longitudinale, lui conferant un aspect lamelleux. La lame interne est courte et maigre, plongeant a la verticale. La fossula est etroite mais en cuilleron, legerement concave, portant comme I' aire columellaire de gros denticules funicules rejoignant les denricules de la levre interne. La denriculation de la levre interne est limitee a I' aire columellaire par I' angulation abrupte. I:arete adapicale de la Jevre interne forme une callosite massive. Le canal exhalant est court, formant un pontet a peine marque. La levre externe presente un rerrecissement pince en son quart anttrieur. |
