Varicospira Kooli

Stromboidea


Original description of Varicospira kooli by Moolenbeek & Dekker, 2007:

  • "Shell slender, rather solid with about 9 whorls. Lenght 23.2 mm, width 9.5 mm. Protoconch of two rather blunt whorls, followed gradually by a sculpture of only axial riblets. After about 10 axials riblets, gradually fine spiral grooves appear in between two axial riblets. The ribs are always more prominent than the spiral ribs. On the penultimate whorls about 32 rather strong axial ribs are crossed by 9-11 spirals grooves. Bodywhorls with 13 axial ribs, which are complete on the dorsal side, followed by about 16 axial riblets, only visible just below the suture. The greater part of the ventral body whorl is (glossy) smooth with hardly visible minor spiral grooves. Columellar callus strong. Anterior canal short and upturned. Posterior canal open, long, weakly curved (opisthocline), ending two whorls beyond the bodywhorl. Outer lip (varix) strong, heavy, with only a few axial growth lines and with three tiny denticles near the anterior canal. The strong outer lip is slightly curved with a hardly visible “stromboid notch” and with about 17 ridges on the inner side and two or three hardly visible denticle-like ridges on the upper columellar side. Colour creamy tan with irregular brown blotches finally ending in three indistinct brown spiral bands on bodywhorl, more pronounced on the upper part of the cream coloured varix. Ventral part of body whirl with a central band of fine zig zag marking. Aperture (inside) slightly translucent apart from the white inner varix and the white columellar callus. Anterior canal violet. Posterior canal creamy with dark brown edges."
