Agathotoma Alcippe
''Agathotoma alcippe'' is a species of sea snail, a marine gastropod mollusk in the family (biology), family Mangeliidae. Description The length of the shell varies between 5 mm and 11 mm. (Original description) The minute shell, which is either whitish or pale brownish, is subcylindrical and turreted in shape. The protoconch features a projecting, minute subglobular Apex (mollusc), apex and comprises about 1½ smooth Whorl (mollusc), whorls. This is followed in the teleoconch by approximately 4½ sculptured whorls. The spiral Sculpture (mollusc), sculpture consists of minute, close-set threads that uniformly cover the entire surface.

The axial sculpture is characterized by prominent, slightly protractively oblique ribs (seven or eight on the body whorl), with wider interspaces. These ribs extend over the entire whorl and are prominent at the shoulder, but they are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agathotoma Castellata
''Agathotoma castellata'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains mm, its diameter mm. (Original description) The white, oblong, turreted shell has 6 to 7 whorls, including two in the protoconch. This shell is elegantly formed, with whorls that are narrower at the base than above, giving it a turreted appearance.

Agathotoma Candidissima
''Agathotoma candidissima'', common name Cox's mangelia, is a species of sea snail, a marine gastropod mollusc in the family Mangeliidae. Description The length of the shell varies between 4 mm and 11 mm. The white, oblong, turreted shell features 7 to 8 whorls, with the protoconch missing in the specimen described.

A few faint dots are also present between the ribs, just below the suture. The aperture is elongate-ovate, accounting for approximately 3/7 of the shell's total length. The ou ...
