Description

This marine species occurs off Papua New Guinea.

Description

" The length of the shell measures 4 mm, its width between 2½ and 2¾ mm. The small, white shell has an oval shape and is imperforate. It is rather smooth, with very fine growth-striae and a few riblike varices on the body whorl. The whorls number about 6, of which the two apical ones are mucronate, the other whorls are convex with a deep marginate suture. The aperture is subovate. Its upper angle is moderately acute. The right margin is thin, slightly expanded, regularly flexuous, stronger so near the upper part. The columellar side is slightly arched, a little thickened near the base, with a thin layer of enamel on the body whorl. The operculum is thin and horny.

The species vary slightly in shape, some specimens being more swollen than others, which may depend on sex. The varixlike striae on the last whorl are remarkable," [2]

gollark: The problems I think are problematic are mostly stuff like "intellectual property is somewhat weird and broken", "pricing of some goods (housing, mostly) is weird too", "education frequently doesn't work as well as it should", "there are big technology/surveillance monopolies which are not good", and "government decision-making is pretty poor".
gollark: Blame it for not redirecting to HTTPS like my *cool* website.
gollark: Well, they have short descriptions of many of the ideas on the website.
gollark: I have not actually read any of it. I just said it seemed interesting as an idea.
gollark: There's this interesting book (http://radicalmarkets.com/) - I haven't read it, but I have heard lots about it - apparently it has policy proposals for reworking markets to do some stuff more effectively, which is what I'm interested in.
