Description

The height of the shell reaches 1 mm. The shell has a heliciform shape. The thin spire is short, narrowly perforate, and semi-pellucid. It has a white color with a caducous rather thick pale olive epidermis. The spire consists of three whorls, the first ? (abrupt), the second a little convex, somewhat planulate above and radiately arcuately plicate. The body whorl is large, having a thin double carina (slit fasciole) a little above the middle, radiately arcuately plicate above the carina, below it with stride of growth. The large aperture is irregularly circular, and very slightly expanded at the basal margi. The peristome is continuous. The deep, narrow slit is situated between the two thread-like keels. ([5]

Distribution

This species occurs in the Southern Indian Ocean off Kerguelen Islands.

gollark: Thus far testing has not gotten any actual attack to work due to the sheer badness of RPNCalc string manipulations but we think it may be possible.
gollark: It turns out that it has literally no sanitisation of output and does innerHTML a lot.
gollark: Important announcement: RPNCalcV4 has been shown to possibly be vulnerable to XSS attacks. Please do not execute untrusted input with HTML-looking things in it.
gollark: I retroactively disagree with the editated version.
gollark: Yes, I agree completely.
