The middle one of the top pic's group 3 is the very rare Archachatina spectaclensis, known to be very nearsighted and requiring large print for reading. No known wild populations exist but many can be found in optometrist's offices.

Hey, Polyped congratulations on all those nice shells, you have done well ! I agree with Coyote that the middle one of group 3 is indeed the very rare and elusive A. spectaclensis, but not only that it seems to be froma nigrescens. Indeed a remarkable find ! What is the diopsis ? ;D

Hi Polyped ! ;D Sorry we teased you yesterday because you left your glasses on the table. Actually it is a good reference to get a size perspective. I got a couple of points on the Archachatina names. 2. The last shell on the right is probably better refered to A. marginata chenchi, the same as your no. 10. 5. Looks more like A. degneri because A. ventricosa and A. ventricosa spectaculum have a very granulose shell surface, and your specimens seems smooth. 7. The nominate species is A. papyracea, with A. papyracea adelinae being a form where the dark banding is reduced or totally lacking in the top half of the body whorl ( like the first two shells in the second row). 9. I think this albino shelled form is better refered to A. marginata candefacta. I have never heard of "A. marginata boetgeri", though Boettger did illustrate an albino shelled A. marginata in 1905. 11. All specimens of A. bicarinata are naturally sinistral, just to clarify cos you put "(sinistral)" Please keep us updated.

9. Archachatina marginata var. boetgeri (apex and columella are red - will be published 2011/2012 in Vienna Museum) ....................................................................................... WOW. Interesting to read the Vienna Museum will be describing a new form of marginata. Please keep us posted on this. It must be the one I mentioned was figured by Boettger in 1905, well over 100 years ago. Seems to me it must therefore be pretty rare ! How many you got Polyped ?

Hi ! On the Achatina picture : What is the difference between N°. 11 and N°. 12. ? They both look pretty much the same, except those in the top row are larger. For example see the 2 with blue ring. Also on the top row what is the difference between N°. 14 & N°. 15 ? Sorry the quality of the photo does not show enough details to understand the separation you made. Thanks ! Attachments:
