Atlanta inflata Gray, 1850

This species has a shell morphology very similar to A. helicinoidea. The two species can be easily identified if the eyes are present, since A. inflata has eye type a and A. helicinoidea has eye type c.

 

Synonyms:

Atlanta quoyana Souleyet, 1852

Atlanta quoyii Gray, 1850

  • The spire is flattened with 4¼ to 4½ whorls and is heavily ornamented with multiple continuous spiral ridges. This can make it difficult to identify the whorls, particularly the second whorl which is often narrow.

  • The spire can be a tan-brown colour, or pink-purple.

  • The keel is tall, sometimes with a yellow-brown base.

  • Adult shell is small, reaching only 1.5 mm.

  • This species has not been found in the Atlantic Ocean.

  • Eye type a, operculum type c, radula type I.
