Kylix Paziana
''Kylix paziana'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The size of an adult shell varies between 12 mm and 17 mm; its diameter is 5 mm. (Original description) The small, acute shell is pale olivaceous. It contains 10 whorls, of which the first in the protoconch is smooth and the second obscurely peripherally keeled. The subsequent whorls are normally sculptured. The suture is distinct The periphery of the upper whorls is nearer the succeeding than the preceding suture. The anal fasciole is constricted but crossed by the ribs. The spiral sculpture consists of (on the upper whorls 4 or 5, on the body whorl about 14) strong cords with narrower groove-like interspaces, extending from the fasciole to the siphonal canal.

Kylix Panamella
''Kylix panamella'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The shell grows to a length of 14 mm, its diameter 6 mm. (Original description) The small, polished shell is white, with, on the body whorl and in the throat, a livid pinkish tint. The shell contains 10 whorls. The protoconch is eroded, but its first whorl is flattish and appears from above discoid and glassy. The subsequent whorls are glistening, constricted and appressed at the suture. These whorls contain (on the penultimate whorl eighteen) arcuate and protractive axial ribs which extend from the suture to the siphonal canal except over the last half of the body whorl. The constriction which indicates the anal fasciole gives the posterior edge of the whorl a marginate appearance, but does not interrupt the ribs, which are very prominent in front of the fasciole at the shoulder. The whole surface is evenly sculptured by strongly incised, almost channelle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kylix Impressa
''Kylix impressa'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The shell grows to a length of 14 mm.

Kylix Hecuba
''Kylix hecuba'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The shell grows to a length of 11 mm, its diameter 4.5 mm.

Kylix Alcyone
''Kylix alcyone'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The shell grows to a length of 15 mm, its diameter 4.5 mm.
