Description

The size of the subfusiform shell varies between 14 mm and 25 mm. The shell surface is chalky white, crossed by horizontal purple to black streaks on the seven rounded axial ribs, that are twisted and swollen at the base of the body whorl. There are also eight or nine spiral riblets. The low spire is globose and consists of two and a half whorls, sitting op top of four body whorls. As each subsequent whorls rises above the shoulder margin of the previous whorl, the sutures are not visible. The body whorl is large and almost spindle-shaped. The ovate aperture has a small anal canal that point slightly backwards. The outer lip is crenulate, but has a smooth inner surface. The columellar lip is callused. The siphonal canal is moderately long and, typical for this genus, fused above, almost sealed below and pointing to the left at its base. [2][3]

Distribution

This species is distributed in the Pacific Ocean along the Galápagos Islands.

gollark: See, us humans have *amazing* abilities when it comes to ignoring things which don't directly affect us.
gollark: Anyway, you could probably make reasonable ethical arguments that I should be vegan instead of vegetarian, but I don't actually care.
gollark: The better argument, I think, is that you can't go around objectively measuring what we "should" do somehow.
gollark: That's like saying "the fact that some people believe the earth is flat is evidence enough that there is nothing objective about the eath's shape".
