Scalarituba Weller, 1899

Description.-Intergenic or endogenic linear burrow made in regular and planar or irregular and nonplanar or planar meander patterns. The convex hyporelief, Nereites view, is a series of regular or irregular biserially arranged lobes and pustules. The concave epirelief, Phyllodocites view, consists of a median furrow with lobes on both sides. The median furrow is 4 to 5 mm wide and has a rounded bottom. Narrow ridges, more or less regularly spaced and in clusters of 3 or 4 and bowed in the same direction, cross the median furrow and continue a short distance along the sides. Forward movement is implied as opposite the direction of bow of the peristaltic furrow ridges
