Description
The height of the small, milky-white shell attains 6 mm, its width 2.25 mm. It has an ovate-fusiform shape. It contains 8 whorls. The body whorl is bicarinate. A very beautiful spirally carinate and lirate species. The short canal and wide sinus proclaim it rightly placed in Microdrillia and the acute carinae are peculiar. The aperture is oblique and oblong. The columella contains no plications.[2]
Distribution
This marine species occurs from the Gulf of Oman to Transkei, South Africa
gollark: It is also really hard and has one long-standing bug which you have to manually patch.
gollark: Krist is not distributed/decentralized. Anyone can run a node, given that they're willing to go through the horrible, horrible configuration and meddling involved (it's unsupported and thus quite irritating), but they won't network together.
gollark: You can't just "disable the anti-siri protection".
gollark: But seriously, READ THE SAFETY NOTICES. https://osmarks.tk/p3.html#3-1
gollark: I suppose it's okay as you don't have a ██████ Siri instance *anyway* and we probably got rid of all the extant ones.
