For some older references on shell resorption see:
Crosse, H. & Fischer, P. 1882. Note complementaire sur la resorption
des parois internes du test, chez les Auriculidae. Journal de
Conchyliologie 30:177-181. and in the same volume
____________________ 1882. Note complementaire sur la resorption des
parois internes du test, chez les Olivella. Journal de Conchyliologie
30:181-183.
I apologize for the lack of diacritic marks but my computer does not
like them.
There are many other older papers on the subject.
