| Dutch Name | Arkvorm Parelmossel | |

| Range & Habitat | The Arc-form Pearly Mussel or Sugarspoon lived in the United States of America. It was found in the states Alabama, Kentucky, and Tennessee. This freshwater species occurred in the Cumberland and Tennessee River systems. The Arc-form Pearly Mussel was found in medium to large rivers in shoal and riffle areas. (Bogan, 2000) | |
| Reproduction | It was a winter breeder. (Bogan, 2000) | |
| History & Population | The habitat of this species has been severely modified or destroyed by damming. Damming along the entire river systems and also pollution had a negative impact on this species. Annual surveys are conducted throughout the whole system and the species has not been collected for over 50 years and probably went extinct in 1940. (Bogan, 2000) | |
| Extinction Causes | Habitat modification and destruction by damming. Pollution also contributed. (Bogan, 2000) | |
