Subject: Question concerning Zoila friendii vercoi Schilder, 1930.
> Hello,
>
> I have a question for the Cypraeidae experts out there. In my
> collection, I have the
> following specimen (with data from original label):
>
> Zoila friendii deep water form
> Gray 1831
> Cervantes Island, Western Australia
> Found by diver at 20 metres on sponge
> 83mm
>
> I've compared it with the following typical specimen (with data from
> original label):
>
> Zoila friendii Gray 1831
> Garden Island, South Western Australia
> By diver, on sponge, at 20 meters.
> 79mm
>
> The specimen from Cervantes Island is much more inflated in appearance
> than the typical the Garden
> Island specimen. Furthermore the Cervantes Island shell has a bluish
> dorsum with overlying
> brownish spotting, the margins are lighter in color (edged with dark
> brown) and noticeably
> spotted. The anterior canal is less rostrated than in the Garden Island
> shell. The base of the
> shell is brown with light tan near the margin and extremities.
> I see from maps that Cervantes Island is farther to the north than
> Garden Island. My
> questions are as follows:
>
> 1. Do the known ranges of Z. friendii friendii and Z. friendii vercoi
> overlap?
> 2. If so, by how much?
> 3. Do Z. friendii friendii and Z. friendii vercoi occupy the same habitat
> within the same range?
> 4. My Cervantes Island specimen seems to fit the criteria for vercoi as
> listed in Lorenz and
> Hubert. Could my Cervantes Island specimen be a vercoi?
>
> Any help you can provide will be greatly appreciated. Thanks in advance
> and I'll look forward to
> hearing from you soon. :)
