Description

The length of the shell attains 6 mm, its diameter 1.5 mm.

(Original descriptio,) The minute shell is white, or with faint yellowish flammules. It contains six brilliantly polished, slender whorls. The nepionic shell is small, depressed and smooth. The subsequent whorls show about ten axial riblets, slightly flexuous near the suture and becoming obsolete anteriorly. The peripheral part of the body whorl is smooth or destitute of spiral sculpture, which on the base and the siphonal canal is well developed and consists of fine striation. The notch is short, subcircular, leaving no fasciole. The outer lip is slightly thickened, not lirate within.[2]

Distribution

This species occurs in the Gulf of Mexico and the Caribbean Sea; in Puerto Rico at depths between 46 m and 101 m.

gollark: Some very rough ideas for how to detect similar images:- remove blank space at top/bottom/sides and do the rest of these- run OCR over the text and check for matches- split image up into chunks, reduce the color space a lot, count how many times each color appears, check for similar chunks in other images- run edge detection on them, get locations of edges, fuzzy matching of those- ML-based object detection?- some sort of locality-sensitive hashing for image data
gollark: Probably, but I don't know what software or have any idea how it works.
gollark: Or look at how the repost detection bots do it.
gollark: Really? I'll have to look into this then.
gollark: There are probably freely available machine-learning-y things for it, I guess? And you could definitely read some of the *text* in them.
