Species / Dolomena Abbotti


Original Description of Dolomena abbotti by Dekkers & Liverani, 2010 :

  • "Description: Shell of medium size (average between 25 and 38 mm), solid, with a largely flaring outer lip, body whorl somewhat squarish in appearance because of the knobbed angulated shoulder and the second row of nodules between the shoulder and the siphonal canal. Shell dull. Spire with 9 whorls plus final whorl. Protoconch very small, about 2.5 whorls, glossy and smooth. Postnuclear whorls decorated with spiral threads leading to spiral lines on later ones. Distinct axial ribbing generally occurs on later whorls; knobbed on the shoulder. The sculpture does not get a cancellated structure as the axial sculpture is dominant. Final whorl with distinct spiral ribbing crossed by axial ribbing, with small to rather large knobs on the shoulder. On the ventral side the ribbing gets obsolete and the shield gets glossy and smooth. Outer lip flaring, attached to the penultimate whorl at the shoulder, then abapically curving outside and adapically again curving into a slightly forward pointing tip of the outer lip. There is a deep furrow along the entire outside of the lip, about 4 to 8 mm. from the border, which climbs up to the suture to form a big ridge. Columella with heavy callus, white and shiny, in old specimens with a silver gloss at the outer edge of the callus. Inside of lip thickened, white and with a silver gloss in old specimens. Inside of aperture white with numerous lirae leading deep into the mouth. In the mouth, the lirae get a brown colour. On the side of the columella, the adapical part has about 6-8 lirae forming little knobs at the posterior end. There are also some 10 lirae on the abapical end. All these lirae are of the same colour as the columella: white. The stromboid notch in the outer lip is deep, generally deeper than the sinus of the siphonal canal."

Locus typicus: off Phuket island, Thailand, Andaman Sea

Habitat: "Dredged in 6 to 44 fathoms on muddy sand or broken shells bottom (Abbott, 1960). It probably lives in silty-muddy bottoms at 10-50 m."

Etymology: "The species is named in honour of R. Tucker Abbott, author of many shell books, and the first modern author who monographed the family Strombidae"
