lambis rugosa or lambis arthritica

[spikeybabee]

Hi,

I had some shells posted on eBay that I posted as lambis rugosa as I thought that is what we bought many years ago. I had a user contact me and state that they were in actuality, lambis arthritica, but offered no further explanation even after I asked.

So . . . I am hoping that someone here can help me. I ended the listings that I had and have looked, but can't figure it out.

Here is one of the ended listings:

If the other two listings need to be seen as well, please let me know. I ordered all of these shells at the same time, so I assume that they are all the same.

Thanks so much.

Debbie
