Description

provided by NMNH Antarctic Invertebrates

Typhlodaphne strebeli n.sp., Pl. IX, fig. 53

This species differs from the glossy, milk-white purissima in being uniformly warm-buff, more slender, with a smaller protoconch and with flexuous, subobsolete axials over all post-nuclear whorls. Shell elongate ovate-fusiform, with a tall spire, slightly less than height of aperture plus canal. Whorls 6½, including a small, smooth, papillate protoconch of 1½ whorls. Post-nuclear sculpture of narrow, flexuous, protractive, closely spaced axials, commencing just below the slightly concave shoulder, but becoming subobsolete towards the lower suture and on the base of the body-whorl. The axials number from eighteen to twenty-four on the spire-whorls. Sinus subsutural, occupying the shoulder, steeply descending at first and then produced forwards in the arcuate sweep of the outer lip. Aperture narrowly ovate with a rounded, broadly channelled anterior end not constricted and scarcely differentiated. Surface with numerous microscopic spiral lirations, not distinct enough to be counted.

Height 20.0 mm.; diameter 7.25 mm. (holotype).

Height 24.5 mm.; diameter 10.0 mm. (St. 160= topotype of purissima).

TYPE LOCALITY. St. 388. Between Cape Horn and Staten I., 56° 19½’S, 67° 09¾ W, 16 Apr. 1930, 121 m.”

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.
