Dear friends
This question is for all the people that are interested in cassids or in
European molluscs. From some months ago I have been studying the cassids
from Canary Islands and I found that the species Semicassis (S) granulate
granulate doesn't exist in Canary Islands, all the specimens that I found
that are similar to this species are lately confirmed to be a undulatum
(using opercula studies). If I haven't in a mistake that’s confirm that
Semicassis granulate undulate isn't really a subspecies because there is an
special segregation, so Semicassis undulata can be considered a specie
itself. For ensure my hypotesis I need some collaborators from canary or
people that have Semicassis granulata from this place, with o without
opercula. Can anybody help me?
Regards
Antonio Agüera

Asunto: Re: A few Conidae Questions

Apropos of DNA studies. Can anyone help me?
I live in Lanzarote, Canary Islands. We use to find a small-medium Conus,
called Conus guanche.
according to the Lauer's work, the Conus guanche is found in Tenerife and
the Lanzarote's species belongs to ssp. Conus guanche nitens.
It makes a lot of morphologic and morphometric comparisons to reach the
results but ... here is my problem.
We find a lot of specimens that grows much more than his biggest size for
nitens, and also the spire shape is not the same in every cases. Till I know
the Conus guanche is not reported from Lanzarote, but only ssp. nitens
Anyone knows any work studying the DNA of this species and its status?
Thanks
Javier López
