Description

The length of the shell varies between 7 mm and 11 mm.

The small shell has a warm yellow brown color. It has a blunt short smooth protoconch of a 1½ whorl, followed by five or more subsequent moderately rounded whorls. The suture is distinct, appressed and moderately constricted with three or four fine spiral striae on the fasciole. The spiral sculpture consists of (on the penultimate whorl between the fasciole and the succeeding suture about six) fine equal, equally spaced threads, with narrower deep interspaces, forming minute nodules where they cross the ribs. On the body whorl the threading continues hardly altered, to the end of the siphonal canal. The axial sculpture consists of (on the penultimate whorl about 35) narrow ribs with subequal interspaces, extended from the fasciole to the siphonal canal, forming a very uniform reticulation over the whole surface. The aperture (the outer lip defective) is rather wide. The inner lip is erased. The whitish columella is short, stout,. The siphonal canal is very short and wide, hardly differentiated from the aperture.[2]

Distribution

This species occurs in the Sea of Cortez, Western Mexico; off the Virgin Islands; St Vincent; Aruba; off Western Africa and in the Alborán Sea, Western Mediterranean Sea.

gollark: Fortunately, all the genes for tails are still there but commented out.
gollark: Reject cat eyes, use octopus eyes. Or maybe cuttlefish.
gollark: If you change one base pair it probably shouldn't affect more than one protein.
gollark: Each gene makes one protein in normal circumstances as far as I know. A protein is a sequence of animo acids, which are defined by 3 base pairs each.
gollark: Some things are simple and controlled by one gene, like basic hair color and some genetic diseases, but others are horribly complex and have a ton of related genes and environmental factors, like intelligence and height.
