Typhlodaphne strebeli Powell 1951

Typhlodaphne strebeli is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.^[1]

Description

The size of an adult shell varies between 15 mm and 30 mm. The elongate, ovate-fusiform shell has a buff color. It differs from Typhlodaphne purissima (Strebel, 1908) by being slender, having a smaller protoconch (1½ whorls) and showing flexuous, closely spaced, subobsolete axials (numbering 18 to 24) over the 5 whorls of the teleoconch. The shoulder is slightly concave. The narrowly ovate aperture has a rounded anterior end. Across the shell run numerous microscopic lirae.^[2]

Distribution

This marine species occurs along the Tierra del Fuego.
