EULIMA CONVEXA.

(Pl, I., figs. 9, 9a.)

Shell small, elongate, pellucid white, exhibiting the red dried remains of the animal, smooth, glossy, rather blunt at the apex; whorls 8, a little convex, slowly and regularly increasing, narrowly marginate beneath the slightly oblique suture; aperture ovate, acuminate above; peristome whitish, the outer margin curved forward in the middle, somewhat sinuated above and at the base; columellar margin thickened, reflexed, joined above to the outer lip by a thin callosity.

Length, 5.75 millim.; diam. 2; aperture, 1.5 long, 1 broad.

Holes 9, 12. In 25-51 fathoms.

The whorls are more convex than in many of the known small species. E. amblia, Watson, from between Marion an.l. Prince Edward Islands, has longer and flatter whorls, a longer aperture, and is smaller.”
