Bad cowries - conchylinet - 03-03-2012 Hello, I need help with the cowries below. They are from Indonesia (and beached condition) Thank you Pierre A- 42 mm B- 76 mm C- 32 mm Re: Bad cowries - Emma - 03-04-2012 Hello Pierre! I'd say the first and the third are Mauritia arabica (I have some in similar condition from Papua New Guinea). If you cover the top of a Mauritia arabica in acid it is purple (I was given one, I haven't done this myself); you also see this purple covering in other cowries (annulus, if I am not mistaken). With regard to the Bulla stage, I'm not so sure, I'd suggest Chelycypraea testudinaria; I don't think it is tigris this time. But, as always, I am not sure of the location of C. testudinaria so somebody will probably correct me. I hope this helps, Best wishes, Emma. Re: Bad cowries - Emma - 03-04-2012 The first one may be Mauritia arabica immanis. I have a similar beach-collected one from Australia. I say this because the immanis form is more "compact" in my opinion than the normal arabica arabica. Re: Bad cowries - conchylinet - 03-06-2012 Thanks a lot Emma, I am ok with testidunaria as it is found in the area. Pierre Re: Bad cowries - dave r - 03-07-2012 Emma, arabica immanis is endemic to the Western Indian Ocean, they are not found elsewhere. Also I do believe it is a species in its own right now.. Re: Bad cowries - Emma - 03-08-2012 Thanks Dave, I'll post a picture. I felt sure mine was an arabica imanis imanis by the shape and the specimen is definetely from Australia. Emma.

So, it's probably better I post a photo on the forum. Best wishes, Emma.
