Actinella promontoriensis Waldén

Madeiran Actinella Snail (Actinella promontoriensis)  

This species was endemic to the island of Madeira.

The species is rare in the fossil record, first appearing in Late Pleistocene deposits, the youngest shells could be dated to an age of about 200 years, thus this species apparently disappeared sometimes in the early 19th century. [1]
