Description The length of the shell attains 14 mm, its diameter 5.5 mm. The biconic-claviform shell has about two whorls in the protoconch and five weakly convex whorls in the teleoconch. The shell shows 10 to 12 axial ribs on the early whorls and 9 to 11 on the penultimate whorl. The ribs only occupy the lower two-thirds of the whorl, the remainder being simple. The spiral striation is fine; that towards the base of the body whorl is a trifle coarser. The aperture is oblong. The siphonal canal is wide. The columella is slightly convex and has a moderately thick callus. The shell is orange-red with darker red spots in the intervals on the whorls.

	Psittacodrillia Albonodulosa ''Psittacodrillia albonodulosa'' is a species of sea snail, a marine gastropod mollusk in the family Horaiclavidae. Description The length of the shell attains 8.3 mm, its diameter 4 mm. The small, dark-red shell contains six convex whorls and, contrary to the other species in this genus, the apex is not papilliform but slightly depressed. The shell has 10 axial ribs on the whorls. The body whorl has only 6 or 7 ribs, the last part without ribs. The white marks on the ribs is continued as a white band on the smooth part, but it is superficial and not deeply seated. The shell shows spiral striae over whole whorl, 5–6 on the sulcus, 14-15 (or more) below (visible in worn specimens only between the ribs) and c. 15 stronger and more widely spaced striae on base. The aperture is oblong-ovate. The outer lip has a thin border. The columella is upright and shows a small callus.

	Horaiclavidae Horaiclavidae is a family of predatory sea snail Sea snails are slow-moving marine (ocean), marine gastropod Mollusca, molluscs, usually with visible external shells, such as whelk or abalone. They share the Taxonomic classification, taxonomic class Gastropoda with slugs, which are distinguishe ...s, marine gastropod mollusks in the superfamily Conoidea. In 2011 this family was split off from the family Pseudomelatomidae (formerly the subfamily Crassispirinae McLean, 1971) by Bouchet P., Kantor Yu.I., Sysoev A. & Puillandre N. in their publication "A new operational classification of the Conoidea". It forms a clade together with the family Clavatulidae. It has many characters in common with the family Pseudomelatomidae, except the smaller shell with a low Spire (mollusc), spire, the short siphonal canal and a weak or absent spiral Sculpture (mollusc), sculpture. The radular formula is 1-0-0-0-1, but some species in this family lack a radula. Genera Genera within the famil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
