A question from one of the quiet ones.
In Goto's & Anseeuw book "The Living Pleurotomariidae"
they say that Perotrochus gemma is a form of Perotrochus
quoyanus and not a seperate species. My question is:
Is this accepted as a fact, and if so how is it scientifically
identified?
A. Perotrochus quoyanus gemma
Fischer & Bernardi, 1856
or
Bayer, 1965
B. Perotrochus quoyanus forma gemma
Fischer & Bernardi , 1856
or
Bayer ,1965
Or are they still considered 2 seperate species.
