Description

The length of the shell varies between 8 mm and 15 mm.

(Original description) The shell is six-whorled, with a length of 5.75 mm. The protoconch is clear brown, with three whorls, on most of which there are scalar ridges which are much more closely and regularly set than in Benthomangelia bandella, and do not resemble lamellae. There is only a trace of an antesutural revolving rib in the earlier whorls which vanishes entirely in the later ones, and with it, of course, the tendency to raised points of sculpture. Though its place is marked by a white opacity in the otherwise rather translucent shell. There are thirteen longitudinal ribs on the body whorl, which extend on to the anterior fourth of the whorl instead of vanishing, and are more evident and sharper where they cross the band. While the revolving ribs are less regular and extend partially over the notch-band, which is thus rendered much less conspicuous than in B. bandella. The notch is also less marked and the spire has a stouter aspect.[2][3]

Distribution

This species occurs in European waters, the Northwest Atlantic Ocean (from New Jersey, USA, to Southern Brazil), off the Azores in the Gulf of Guinea and in the Gulf of Mexico.

gollark: Hey, I *said* (GNU[+/])Linux, isn't that good enough for you, Stallman?!
gollark: Yep!
gollark: Also, though this is more personal preference, (GNU[+/])Linux (distributions) has (have):- a package manager useful for general use (the windows store is not really this)- a usable shell (yes, I'm aware you can use WSL, but it's not very integrated with everything else)- lower resource use- a nicer UI (well, the option for one; AFAIK Windows does not allow as much customization)
gollark: I've seen Candy Crush randomly installed on a Windows machine as well as random unwanted gaming-related services, there's advertising for OneDrive in the file explorer IIRC, control over updates is pretty limited though I guess you can do a bit, and by "spying" I don't mean anything targeted but just that it reports quite a lot back to Microsoft.
gollark: <@151391317740486657> So telemetry/spying, in-OS advertising, uncontrollable updates, random useless programs being installed, and that sort of thing don't happen to you?
