Cyclostrema
''Cyclostrema'' is a genus of sea snails, marine gastropod mollusks in the family Liotiidae. ''Cyclostrema'' is a neuter word, but many authors have considered it feminine, including Captain Marryat himself. A complete revision of the family Liotiidae is under way (2013). Many species, now included in ''Cyclostrema'', will eventually end up outside the family Liotiidae. (pers. comm.) Description The characteristics of this genus are: The depressed shell is white, or uniformly colored. The body whorl is obliquely striate. The spire short. The aperture is circular. The umbilicus is very large with the volutions of the whorls visible within it. The surface contains spiral ridges and is cancellated. Species Species within the genus ''Cyclostrema'' include: * '' Cyclostrema alveolatum'' Jousseaume, 1872 (taxon inquirendum) * '' Cyclostrema amabile'' (Dall, 1889) * '' Cyclostrema annuliferum'' Dautzenberg, 1910 * '' Cyclostrema archeri'' Tryon, 1888 * '' Cyclostrema bibi'' Es ...

Cyclostrema Cancellatum
''Cyclostrema cancellatum'' is a species of sea snail, a marine gastropod mollusk in the family Liotiidae. Description The size of the shell varies between 8 mm and 15 mm. The white, sublenticular shell is flattened convex above, more convex below. It contains oblique radiating riblets, interrupted by an obtuse peripheral rib The interstices of the riblets are finely spirally striated. The umbilicus has a moderate size. (Description by W.H. Dall) The thin, white shell has a planorboid shape with 3½ whorls. The radiating sculpture consists of about fifteen ridges, faint on the base and summit, making small nodules where they cross the fine spirals, and prominent and strong on the periphery between the three peripheral carinae. Other radiations are only due to lines of growth which are sometimes slightly elevated. The spiral sculpture consists of three prominent and strong peripheral ridges, of which the uppermost forms the chief periphery. The others are slightl ...
