Description

(Original description) This delicate, small shell has an elegantly fusiform shape. It is rather narrow, and gradually attenuate upwards. Its color is white, semidiaphanous. The shell contains 7-8 whorls 7-8. The whorls of the protoconch are smooth, white, and globose. The third whorl is elegantly but microscopically decussate. The remainder are angled a little below the sutures, delicately semitransparent, regularly cancellate. The interstices are quadrate. The longitudinal ribs of the body whorl are slightly oblique. The aperture is oblong. The outer lip is incrassate. The sinus is well defined, broad but very shallow. The columellar margin is fairly straight. The siphonal canal is short and a little recurved.[1]

This marine species occurs in the Indian Ocean off Réunion

gollark: What? Why is that a config file?! You should be defining routes in your code.
gollark: Yes, that is a bit weird and not ideal.
gollark: In JS many config files are just JS.
gollark: But the thing is, YAML has rules of some sort, which you have to understand in many weird edge cases, but they're too complicated to memorize or something.
gollark: English is not machine-parseable. Unlike Lojban. Lojban config file WHEN?
