Ampullataria rotunda - after Decloitre, 1952

 

 

Genus Ampullataria Decloitre, 1952

 

Diagnosis: Test ampulla-shaped, covered with elliptical plates just as in Euglypha species. The plates cover each other partly. The main part of the test is ovoid with a straight tubular neck and a smooth apertural border. These neck has a different structure: the plates are irregularly shaped and don’t overlap.
