Provanna is a genus of sea snails, marine gastropod mollusks in the family Provannidae.[1]
The species was named after Dall's first wife.
This is a very old genus with species already existing in Cretaceous seep deposits off Japan (93 - 100 million years ago). The Caribbean and the Pacific fauna were isolated about 3 million years ago by the closure of the Central American Isthmus.
