Description

The length of the shell attains 5 mm.

(Original description) The small shell is yellowish, with a pale siphonal canal. It has a blunt smooth protoconch of two whorls and 3½ subsequent whorls. The periphery is slightly behind the middle of the whorl. From the distinct suture the surface slopes flatly to the subangular periphery, the rest of the whorl is rounded. The spiral sculpture consists of uniform fine threads with narrower interspaces over the whole surface. The axial sculpture consists of (on the body whorl 15) narrow rather sharp ribs with much wider interspaces, obsolete behind the shoulder and on the base. There are also fine incremental lines which roughen the spiral threads. The anal fascicle is inconspicuous, the anal sulcus feeble. The aperture is simple. The outer lip is sharp. The axis is pervious. The columella is attenuated in front. The siphonal is canal short.[2]

Distribution

This marine species occurs off California, USA.

gollark: More properly known as a geometer, actually.
gollark: So *that's* why my Earth detector said the planet ceased to exist a few days back.
gollark: Oh, I'm using the European bismuth scale.
gollark: It scores 94.3 on the standardized bismuth bismuthness scale.
gollark: I don't know what tuff is, that's definitely bismuth.
