  A new Vermetidae from the Eastern Atlantic: Vermetus bieleri n. sp. (Gastropoda Caenogastropoda)

  ABSTRACT
  A new species of the worm-snail Vermetus Daudin, 1800, V. bieleri n. sp. (Gastropoda Caenogastropoda), is here described as new for Madeira and the Canary Islands. The species morphologically resembles the Mediterranean congener V. triquetrus Bivona, 1832, from which it is here distinguished on the basis of morphological characters of the shell, the protoconch and the external soft parts. Comparisons of the new vermetid with other similar species are hereafter reported.
