Atlanta lesueurii Gray, 1850

This species has a similar shell morphology to Atlanta oligogyra. The main identifying feature is the deeper sutures of the spire. Juvenile specimens can be difficult to identify from Protatlanta souleyeti, which also has very few whorls in the spire.

 

Synonyms:

Atlanta primitia Smith, 1888

  • The spire is very small, with only 2½ whorls and has no ornmentation.

  • The sutures of the spire are deep, so that the individual whorls can be seen.

  • The adult shell is colourless and up to 6 mm. Only a single adult whorl is formed, giving the adult shell an elongate shape.

  • The keel is tall and inserts a short way between the final and penultimate whorls.

  • Eye type b, operculum type b, radula type I.
