Anybody got an idea what species this is ? It came from an old shell collection, the only data is West Africa. Length is 134mm. Attachments:

I would guess a cinnamomea, but its just a guess.

Thanks for the tip Frisen.
But following up on your lead I read cinnamomea is an Archachatina, to be exact : Archachatina cinnamomea Melville & Ponsonby, 1894, native to south Africa.
The specimen in my image is definately an Achatina sp., not an Archachatina. Check out the excellent link Paul made on this homepage - its in the Quick Links in the grey box on the left "Achatina or Archachatina ?".
Anybody else got any ideas ?

Yes i know its a Archachatina, but from shell shape and colour i would still say they look quite alike, ofcause I might be totally mistaken. How come your so sure its an achatina? - I mean Compendium of landshells says one of my snails are extinct, but you already this  What size is the shell? /F. |

Attachment: Achatina sp. 134mm West Africa CPR.jpg The answer for size is in the caption for the photo : 134 mm. Thats medium size for an Achatina. The answer for Achatina...or.....Archachatina.....is in Paul's link ( see www.petsnails.co.uk/ ) |

The answer for Achatina...or.....Archachatina.....is in Paul's link ( see www.petsnails.co.uk/ ) hi Peter, the are similar to the small shell you got from me, suggested A.iostoma (with a little bit redish apex)... but only similar, this isn't species from your pic... Maybe is your A.stuhlmani? pics of the alive snails:     this species below is originated from Congo  C U Peter |

Hey Polyped, thanks for the tip. Sorry I'm late but it took time to find a specimen of Achatina stuhlmani for comparison. Eventually I got one which came from North Kivu, Zaire ( now Congo ). The size of the shell is 140.5mm - quite similar to that of my Achatina sp. without data. But what I noticed is that the surface of the stuhlmani is minutely granulose; the other one is quite smooth. Also some differences in the early whorls. I post here a pic of the early whorls of stuhlmani .....and in the next post I'll post a similar pic of those from the unknown species. Attachments:

Quite apparent is the difference in color. But just how variable can the color be ? Both have darker brown markings. Also noticeable in this second image is a subsutural ramp, absent in the image of A. stuhlmani spire. Again can this be accounted for by the variability withim a species ? Attachments:

"Brunni" this specimen was bought as an Achatina stuhlmani. If the ID was correct, would this photo help you to rule out A. stuhlmani? Attachments:

Thanks Nacre for this image. Nice snail you got there. Can I ask you to look at the underneath of the shell and tell me the colour of the parietal wall and the columella ? ( see "Identifying your snail/species" tab on the homepage if you are unsure of these terms.) I take it the color of the shell all over and inside the aperture is white ? You sure thats not a A. fulica radotzi you got there ( i.e. an albino-shelled fulica ) ? The animal of your snail looks almost identical to one posted by Ratzleopard under the tab "Achatina Fulica (and jades too)" in "Species Pictures for Website ". I hope Ratzleopard doesn't mind, but I copied that pic to here.. Attachments:

I hope Ratzleopard doesn't mind, but I copied that pic to here.. Hi "Brunni" I know the parts of the snail, take my word for it But I can't look at the shell, nor remember how it looked like. The snail was one that I kept many years ago and I thought it might be of some help. I can't tell for sure it wasn't an Achatina fulica rodatzi, because you'd have to dissect the animal and compare the sexual organs (if I don't recall wrong) in order to make a 100% accurate ID. But my personal believe would be no, not an A.fulica rodatzi. Take care and have a nice weekend! Best wishes Fredrik /Fredrik |

Hey Fredrik
That photo you posted of a possible A. stuhlmani.....or an A. fulica rodatzi.............that you kept many years ago. Where is he now ? Is the shell available for study ?
Hey, I'm not going to be dissecting no snails, I have enough problems putting a worm on a hook when I go fishing. But if the shell is around I'd really like to see it. I'm looking for an albino fuli shell for my shell collection. Send me a PM about it.
But I think I have solved the problem of what my shell is = see next post !

Here's another picture on my shell ( I cleaned it up a little since I posted the first picture ). It agrees with the Poppe image in size, shape, colour, extent of brown flammules, rose aped and subsutural ramp. What would be necessary to clinch this identification would be to see an image of the type specimen. It is in the British Natural History Museum. Anybody can help here ?  Attachments:

Thanks Heydihoo, that would be great. I used to have a link to Cathy Wey whom I believe was in charge of the Molluscan section at the museum, but I can no longer find it. Any help is therefore greatly appreciated. I also hear the Cardiff Museum has a good collection of Achatinidae...would anybody know ?? |
