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 suture is distinct and appressed, with the whorls being shouldered immediately in front of it. 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] |
