Description

The length of the shell attains 5 mm, its diameter 2 mm.

The small, white shell has an ovate-fusiform shape. It is very elegant in form, fusoid towards the base. The shell contains six whorls. The three whorls of the protoconch are seen with a lens to be very finely cancellate. The species is remarkable for its acutely angled ridge surmounting the upper portion of the whorls of the spire. The longitudinal ribs (14 on the body whorl) and spiral lirae are extremely pronounced, the interstices being squarely and deeply cut. The siphonal canal is wide and open. The aperture is oblong. The outer lip is incrassate. The sinus is wide but not deep. The columella is rather straight. [2]

Distribution

This marine species occurs in the Persian Gulf and the Gulf of Oman.

gollark: Oh, NOW it pings me somehow?
gollark: You have a reasonable point that you can be nice to people inside a conversation but (possibly inadvertently) non-nice to those outside it. I think niceness within conversations is more important, as people outside them can more easily choose not to participate in them, but this doesn't work excellently. Banning discussion of anything some people do not like reading is *a* fix for some of this, but I don't like the tradeoffs, given the wide range of things in this category. Isolating that elsewhere is also not good for various reasons I indicated before. A generalized rule-4-y approach could end up doing basically the same thing as preemptively banning it, and people seem dissatisfied with "ignore the channel for a bit". Thus, I'm unsure of how the issue can be solved nicely and it's worth actually investigating the options.
gollark: What a strange name.
gollark: You are to wait while I:- type- think- move a mouse cursor around somewhat- get distracted by unrelated topics repeatedly
gollark: Too bad, you are to wait.
