Description

The length of the shell attains 136 mm, its diameter 52 mm.

The turreted, fusiform shell is white. The epidermis is more or less assumed. The spire is elongated and acuminate. The shell contains probably 10 whorls with seven whorls remaining. These are convex, slowly and regularly increasing. They contain oblique and flexuous ribs (with their upper part and lower part fading away) and strong and close spiral lirae. The body whorl is somewhat swollen. The aperture is elongate and measures about half the length of the shell. The siphonal canal is short. The columella is nearly straight. The outer lip is not incrassate and shows a wide, but not deep, sinus at the suture. It is prominent and arcuate in the middle. [2]

Distribution

This marine species occurs in the Bay of Bengal.

gollark: Also, I'm semi-pointlessly asking again: anyone want an Ender Mailbox? I have them sort of half-working (needs fixes and lots of refactoring...). The idea is that you can send mail through ender chests to other people, somewhat securely and possibly automatically.
gollark: All shall be furnaces.
gollark: Alternatively, I'll just make it dump into every ender chest channel so it won't shut down until it makes about 440000.
gollark: Well, anyway, I assume you've shut it down, I'll implement safeguards against this eventually.
