Description

The small, smooth, bright shell has a turbinate shape. The outlines of the spire are convex, variously maculated with rose color and reddish brown. The four whorls are very convex, and rapidly increasing. The body whorl is produced anteriorly, separated by well impressed sutures. The nuclear whorls are regular. The apex is mammillated. The base of the shell is rounded. The umbilicus is carinated. The aperture is scarcely indented by the parietal margin. The acute peristome is nearly continuous. (original description by Carpenter) [4]

Distribution

This species occurs in the Pacific Ocean off Cape St. Lucas, Lower California.

gollark: There's a SBC with that SoC supported by ArchLinuxARM: https://archlinuxarm.org/platforms/armv8/amlogic/odroid-c2
gollark: It's probably ARM, so you need weird special distros because ARM is a mess.
gollark: It has redundant PSUs but I only have one plugged in so the fault warning light blinks constantly.
gollark: I have never tried my server under full load and it never goes anywhere near full load except during boot, so meh.
gollark: Maybe Starlink. Eventually.
