Xanthodaphne Dalmasi
''Xanthodaphne dalmasi'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Subspecies: ''Xanthodaphne dalmasi nuda'' Nordsieck, 1973 Description The length of the shell attains 9.4 mm, its diameter 4.2 mm. (Original description in French) The slender, fragile shell has a fusiform shape. The spire consists of seven convex whorls separated by a rather well-marked suture. The protoconch consists of 5 whorls. The first is finely reticulated by delicate decurrent cords and by other more insignificant longitudinal ones. The others show below the suture a large area decorated with oblique and not prominent ribs and very recurring fine streaks. Below this area they are reticulated. They are followed by two more or less subangular whorls at the lower limit of the infrasutural zone which occupies a little less than a third of the height of the whorl. This area is decorated with regular and tightly arched lines of growth, more accentuated near the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xanthodaphne Leptalea
''Xanthodaphne leptalea'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 24 mm. (Original description) The shell is of moderate size, rather stout, very thin and fragile, delicately tinted with brown below the chestnut-brown tip. It consists of four obtusely shouldered whorls besides the protoconch. The aperture is long, rather broad, pinched in anteriorly, forming a moderately long, narrow siphonal canal. The outer lip is badly broken, but, judging by the lines of growth, sweeps well forward from the posterior sinus, which is as wide as the subsutural band, and deepest next the suture. The columella is very straight with a narrow, very thin, closely adhering layer of enamel. The subsutural band is broad, oblique, crossed by numerous very delicate curved riblets and lines of growth, most conspicuous just at the suture.

Xanthodaphne Agonia
''Xanthodaphne agonia'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

Xanthodaphne Pyriformis
''Xanthodaphne pyriformis'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 7.5 mm, its diameter 3.75 mm. (Original description) The pyriform, ivory-white, thin, fragile shell has an acute spire. It contains 8 whorls 8, of which 4 form a light-brown protoconch. They are convex, with remote riblets on the upper part, oblique, and with less stronger ones, which cross each other, in the lower part. The subsequent whorls are scarcely convex, with only a trace of being divided into two parts on the upper two. However, the upper part is marked with elegantly curved, conspicuous riblets, being slightly bead-like just below the suture, on a narrow, infrasutural spiral. The lower part of the body whorlshows numerous, faint, spiral striae, becoming stronger on the rather long, slender siphonal canal. Moreover the lower whorls display elegantly waved growth-lines.

Xanthodaphne Membranacea
''Xanthodaphne membranacea'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 22 mm, its diameter 13 mm. (Original description) The shell is broad, short, tumid, and membranaceously thin. It has a short spire of few somewhat tumid whorls, which are parted by a slight horizontal suture.
