Blofeld’s Saint Helena Awl Snail (Chilonopsis blofeldi)
Most members of the genus Chilonopsis (eight species are known) were probably extinct shortly after the establishing of settlements on Saint Helena, in the early 16th century.
The final extinction of so many endemic snail species of Saint Helena was probably caused by the nearly complete destruction of the native vegetation by farmers and their domestic animals.
