Need some opinion..

[paul monfils]

Hi Raffy,

There isn't a lot of difference between the two, and like everything in taxonomy it comes down to a matter of opinion whether C. cordigera deserves full species status. I tend to follow Rockel, Korn & Korn (Manual of the Living Conidae), who do recognize C. cordigera as a species. Their descrïption states:

"C. cordigera closely resembles C. nobilis. The latter species differs mainly in its non-tuberculate early and carinate later postnuclear whorls, and its coarse alternating brown and white spiral lines within the larger solid brown areas of its last whorl".  Not exactly a long list of criteria for separating the two!

This is an open forum. No-one needs permission to ask or answer a question.

Regards,
Paul
