extinction date: last seen in 1966

This milky white, brownish or greenish coloured species once occured in large amounts on the beaches and mangrove stands of the Bermuda Islands, where it could be found above the high-water mark in the burrows of other worm species, smaller specimens were found below the high-water mark. During the moister seasons the worms could also be found in places farther inland.

The former habitats of this species were destroyed above all due to development.

Very few - the last of their species - were found during an intensive search operation in the year 1966.
