Description
This is a narrow cytharoid species, evidently a near ally of the protean Paraclathurella gracilenta, Reeve, 1843. The granulately cancellate third whorl hints at identity with this, and also the form of the aperture and outer lip. But the mature shell is more abbreviate and considerably smaller. As E.A. Smith points out, there is much variation in the colour; some specimens are white, others reddish, and we have examples from Hong Kong of a dark greenish brown. [2]
Distribution
This marine species occurs in the Persian Gulf and off Japan.
gollark: Clearly I need to find somewhat bad memes matching *my* political alignment.
gollark: That seems like more of an argument against political instability and dividing up long-lived political union things than against not having communism.
gollark: I have to admit I do like the "concrete and large things of glass" aesthetic, although generally it could use more colors.
gollark: If doing nothing creates more evil than some sort of complex evil-creation system, then a good evil maximizer would decide to switch to doing nothing, if it was made aware of this.
gollark: Probably less bad stuff, though, than an organization which is actively trying to do bad stuff and is somewhat good at it.
