special form of Canarium mutabile

[dave r]

Hi Khan, at first glance this would seem to be Canarium ochroglottis betuleti rather than mutabilis. I know the locality is wrong for this species but it is a dead ringer. Is there any chance you could sell or exchange some specimens with me? I am a Strombidae collector and I would love a closer look at some so I could be certain of the species.
Cheers,
Dave

Like I say holas silly but not the area where they became nuclear evidence; qeu I heard the area there were many specimens with aberrations and is already but it is a hypothesis  <span class="petit">--Last edited by xbonet on 2010-04-28 20:06:44 --</span>

I heard than you can tell the difference between mutabilis and ochroglottis from the tiny ridge on the columellar side of the aperture : mutabilis having a full range of "ridges" and ochroglotis lacking in the middle.

Hi collectors,
Is anybody know if this form of Canarium mutabile have a name ?
or anything else about approaching forms ?

This form comes from French Polynesia where it is locally common.
Average size is about 14mm, always with rosy color, no dense pattern (often almost without pattern).
Mostly found in fine white coral sand near reef, in lagoon, shallow waters.
Thanks !  <span class="petit">--Last edited by khan on 2010-05-05 22:48:58 --</span>

That's right conchylinet, ochroglottis has a smooth area on the middle of the columella whereas mutabilis is ribbed for the whole length. Also mutabilis does not have black in the aperture. Size, colour and pattern all say ochroglottis betuleti, locality says not. But it could be a new locality for it!

Khan, the specimens you have advertised on your website are mutabilis but the one posted above looks very different, that is why I thought it was ochroglottis. It is a different shape, colour and has black in the aperture.

Thanks everybody for answering.
Dave, if you are interesting to buy some specimens, you can find it on my website <a href="http://www.khanshells.com." target="_blank"><!-- w --><a class="postlink" href="http://www.khanshells.com">www.khanshells.com</a><!-- w -->.</a>
I am really not sure this can be a form of C. ochroglottis.
This is pictures of aperture from 2 specimens, maybe to confirm Conchylinet's remark.

I am really sorry, I inverted two images. <img src="images/smiley/bof.gif" alt="" border="0" />
I put the good image of <i>Canarium mutabile</i> from french Polynesia (the dwarf and pink form) in my first message.

The picture below represents a specimen from Thailand, that corresponds better to <i>Canarium ochroglottis </i>:

All my excuses.

Now I can re ask my initial question  <img src="images/smiley/dingo.gif" alt="" border="0" />
Do you know the form of <i>C. mutabile</i> from Polynesia ?
(see below)

Thanks a lot.

Hi Khan, that explains it!
As far as I am aware the form from French Polynesia does not have a name.

Right, thank you Dave
