This characteristics was the distinctive feasture in this taxa ( Lundholm & Moestrup 2000). The vermiform silica ridges was shown to both N. navis-varingica and N. linearis on the exterior valve mantle ( Mann 1980; Kobayasi & Kobori 1988). N. linearis have the vermiform ridges on girdle bands, whereas N. navis-varingica own the girdle bands covered with silica warts ( Lundholm & Moestrup 2000).
