In answer to your question, in the specimens of Acteocina that we get from off San Diego, the spire is extremely variable. I suspect that the spire is relatively fragile in the juveniles and the variability in the adults reflect this condition.
The following species of Acteocina are found off San Diego:
• A. inculta (Gould,1856)-embayments
• A. culcitella (Gould, 1852)-shallow offshore,<30m
• A. eximia (Baird, 1863)- deep offshore,>30m
• A. harpa (Dall, 1871)- offshore
The first three species are very common in our benthic samples and the distibutions are well documented. A. harpa is less abundant and thus its distribution is less certain.
