Description

It is a very changeable species with quite a lot of varieties. There are often anomalies and monstrosities too. On the external lip the four fingerings, changeable in length and thickness, are a characteristic of this species. Shell solid, sculpture made by flexuous axial ribs crossed by one cord originating some nodules quite clear, two cords on the last whorl originating two fingerings. Sometimes there is one third nodulous cord less broad. Surface crossed by very fine spiral little cords. Internally the fingerings are covered with one groove in their median part. Siphonal canal ends in the caudal fingering. From dirty white to brown, to reddish in colour pattern, but there can be found specimens violaceous too. The typical fingerings are missing in the yuvenile specimens but they are easily recognizable. Embryonal whorls show a smart reticulated sculpture. There were described many varieties in form and in colour pattern. It is easily recognizable from its similar one A. serresianus (Michaud, 1828) the shell of which is slighter, with five fingerings narrower and more stretched.
The adult specimens average measures are around 40-50 mm in height.
